Title: Fuel pump problem 2005 Girly
Post by: Fross on November 09, 2014, 10:57:52 PM
Hi everyone, I know I've not posted for a while but I do read what's going on now and again. Now I need help. I have a fuel pump problem that all started with a blocked petrol cap drain. I've been noticing that every time I refuel there is water that runs into my fuel tank when I lift the cap. I tried to blow out the drain hole but couldn't it was seriously blocked. I stupidly ignored the problem until last week when I rode down the road and the engine kept cutting in and out, so much so that I returned and had to use one of my trusty old Nortons instead. I presumed that it was the water in the tank causing the rough running. Today I removed the fuel tank in order to drain it of fuel and water, plus unblock the drain pipe. All this I did without problem.
Once it was all back together I put in 10 litres of fresh petrol and now the engine won't start.:icon_cry: I thought that as I'd emptied the fuel rail supply tube it might take a while to get the fresh fuel to the injectors so kept trying all afternoon, but nothing. The pump used to make that screeching noise that others experience when I first turn on the ignition, but not today. In desperation I removed the fuel pipe from the tank, then connected a piece of hose pipe to see what I get when I turn on the ignition. Absolutely nothing. If I suck on the hose, fuel comes out, so I figure the fuel is there but the pumps not pumping. I tested the pumps electrical connector for power and have 12+ volts at the plug when the key is turned. I've tried wiggling the connector in case there's a bad connection but can't get the fuel pump to run.
Have I missed something or does it look like my fuel pump is kaput? Could it be that the deteriorating fuel pump was my cutting out problem and not the small amount of water in the tank? :icon_scratch:
Any advice will be welcome.
Regards, Fross

It was difficult to tell how much water was present when I drained the tank but I don't think it was enough water to cause the problem.
I'm going to connect 12 volts to the pump connections directly from a battery and if it doesn't spin then I will replace it. I can't think of any other way to test it.

I can't remember if they come apart, but it might be worth checking whether it's just blocked by a bit of crud that'll have been disturbed when you emptied the tank

I've not had chance to investigate further this week. My plan is to remove the pump and bench test it before paying out for a replacement. I suspect the fuel filter has never been changed from when the bike was new so most likely it'll need replacing too. I will post what I find.

I'm still very puzzled and have a very sick Tiger. :icon_cry:
Today I connected test leads directly from the battery to the fuel pump connection and you hear the pump running (a good sound, not screeching). In this state the engine fires but runs very rough as if it's too choked, it cuts out when the throttle is closed (no tick over).
When I reconnect the pump connector (which only reads 11.6 volts with ignition on) I cannot hear the pump run (the battery is fully charged and sits above 12.7 volts). Engine starts once but cuts out very quickly and no longer fires until I reconnect my "pump direct to the battery leads" to put fuel pressure into the fuel rail.
Anyone any idea's whats gone wrong and what I should do next? :icon_confused:

Hey Fross !! Just my thoughts, check big fuse at side of battery box, fuel pump relay or a bad earth somewhere  :^_^

The fuse might look ok but there has been issues with them !!

Good luck

Hi KK, I think you're right I hadn't thought about the basic stuff. I haven't done resistance checks on the wiring to check ground etc. Although looking at the wiring diagram the ground wire from the pump goes straight into the ECM for some reason? I guess it controls it via the ground wire. I'll check all connections in the ignition circuits, plus main fuses.
Unfortunately because the bike's kept outdoors I don't get many opportunities now it's dark so early. :icon_frown:

Sorry not very helpful but I think you're on the right track with Kenny's hints. It's amazing how much poor connections can drop the voltage.

Yesterday I tested for good/bad earth and found nothing but good earth at all crucial points. After playing around with the fuel pump cable connector and carefully cleaning the terminals I discovered it WAS a faulty connection causing the fuel pump not to run. Once this was rectified the fuel pump hums nicely for a couple of seconds every time the ignition is turned on. Fuel pump problem now resolved and engine now starts and but runs terrible (just as it did before I took off the tank back in November).

I have today connected my laptop and erased these two error codes:-
P0230 - Fuel pump relay default
P1231 - Fuel pump relay open circuit or short to ground
(I presume these only appeared because of the bad connection problem that I've now resolved.)

Now back to the original "rough running" problem. :icon_scratch:
I started the bike to let it warm up without touching the throttle (if I touch the throttle I know it would just misfire and stall). Two screen shots as it warmed up below.
Capture1

Now the fan has come on, picture below.
Capture3

I now open the throttle to see what happens and it straight away runs rough with black smoke coming out the exhaust. I am holding the throttle open to prevent it stalling. Picture below.
Capture4
(http://i1374.photobucket.com/albums/ag420/Fross/Tiger%20995i/Capture4_zps5345c2ea.jpg) (http://s1374.photobucket.com/user/Fross/media/Tiger%20995i/Capture4_zps5345c2ea.jpg.html)
I am now trying to hold the engine at idle speed, it is running very rough and the throttle is held partly open. Picture below.
Capture5
(http://i1374.photobucket.com/albums/ag420/Fross/Tiger%20995i/Capture5_zpsd1bf39d1.jpg) (http://s1374.photobucket.com/user/Fross/media/Tiger%20995i/Capture5_zpsd1bf39d1.jpg.html)
This last screen shot is where I opened the throttle to increase engine speed before closing the throttle to see if it would idle. It stalled instantly just after the screen capture. Picture below.
Capture6
(http://i1374.photobucket.com/albums/ag420/Fross/Tiger%20995i/Capture6_zps98ea42a4.jpg) (http://s1374.photobucket.com/user/Fross/media/Tiger%20995i/Capture6_zps98ea42a4.jpg.html)
I'm now at a loss at what to do. :^_^ I have no error codes. The engine runs so rough it can not be ridden.
Can anyone see anything way out in the sensor figures because I don't know what I should be looking for?
Should I try reloading the Map? (it is the standard "10172Map.hex")
I hope someone can advise me. :bowdown
Thanks for reading and Happy New Year to you all. :wave

Air leak somewhere, it's only a guess but I know nothing about the tune side of things but whenever mine has run like a bag of spanners that's what the problems been.

Check the vacuum lines carefully, any cracks or splits get new on there, the IACV on the top of the airbox is then next thing, check it cycles via the tune programme if it's sticky in any way then it'll run rough, either new or some lube that's dry, NOT WD40!
Title: Re: Fuel pump problem 2005 Girly
Post by: Fross on December 29, 2014, 07:57:00 PM
Hi John, thanks for your suggestion.
Just to recap on how this problem all started. During October I noticed that the engine was becoming slightly rougher running very gradually each time I rode. At the beginning of November I decided to do a 12 minute reset to see if it would improve things. It was the next day after the reset that it ran terrible when I tried to ride down the road, as if the reset had made things ten times worse. It was then I thought it must be water in the fuel tank as described earlier in my posts. Removing the tank started the fuel pump issue which is now resolved. The vacuum pipes were all replaced with quality silicone pipes some time ago.
When I start the engine from COLD all is FINE so long as I touch NOTHING, it all goes wrong as soon as the throttle is touched.  :icon_scratch:
This morning when I connected my laptop before I started the engine I ran the fuel pump test, cooling fan test and idle stepper motor test which all sounded like they all worked correctly. :^_^
Title: Re: Fuel pump problem 2005 Girly
Post by: Bixxer Bob on December 29, 2014, 11:38:52 PM
For starters your O2 sensor reading is showing rich mixture, confirmed by the black smoke and needing to hold the throttle open to get some air into it.  Also, the baro reading looks high but could just be the weather.  Check your local weather report and see if the baro reading is similar, or whether there's something on the bike throwing it out.  If the ECU sees a false "high baro" it'll calculate that there's more oxygen in the air than there actually is and so put more fuel in hence being rich.

I still favour a remap; fully charged battery and laptop on mains, blow in 10173 (TOR can). It works ok with a standard can so is worth a try.  Remember to read and follow the TuneECU guide exactly because you want it to reset the trims as well. If it runs ok after a remap, you can then try 10172 if you want.  Another thing, remind me, is your 2005 a "post VIN" like mine?  If it is you need an "Adaptation" not a 12 min tune.

Also, can you get a screen shot of the test page as well?  Need to look at the IACV steps and the idle fuel trim.

For what its worth, mine runs like a bag of spanners on it's own ECU but runs fine on my spare ECU, but I haven't had time yet to see what the difference is, or whether I just have a faulty ECU.

Watching hopefully to see if I can glean some info to fix mine.  I really wish I had a buddy with a similar machine so I could swap parts.  I had two Suzuki DR350's and solved a lot of problems between the two by swapping parts.  It's also how we troubleshoot aircraft in the Navy sometimes.

Most of my stuff is applied logic and I often wonder when I start theorising about how the electronics work whether anyone in-the-know from Triumph or Sagem would nod sagely or laugh their socks off.

My main theory for a lot of these woes, and I've been through it three times now that I can think of, is the weak battery might churn the engine over properly, but can't give enough volts to the ECU for it to work properly.  Once the ECU is on low volts there's no predicting what goes on inside as it needs 12.5 volts to save the latest trim settings as it shuts down when you turn the bike off.  I think this leads to settings that are way off the mark and that, coupled with poor sensor readings also caused by low volts, results in rough or non-running.  A clean remap setting the trims to factory settings gets it running and then the ECU can sort the trims out using the O2 sensor in closed loop running.  An adaptation helps accelerate this process. 

Interestingly,  Chris Canning and I both fond an improvement in how the bike ran after fitting an MOSFET reg/rec which lifted the stator output from barely 12.7v to 14.7v which might suggest there's some evidence that good volts are essential.

Sadly, I can't give you a magic answer to your current predicament.  Each time I've been there the solution has always been, good volts, a remap, coax it into life and then ride it.  If you can give me the screenshot of the TEST page on Tune ECU so I can see the Idel trim and IACV steps we might make a little progress. 

I'm sure that when I compare the settings on my two ECUs I'm going to find wildly differing settings.  I'll try to do that today and get some base figures for you.

Thanks BB, yes I can confirm my Tiger is a "Post VIN" (higher than # 206547).

I've just checked for atmospheric pressure at Met office who state 1040 over UK last night and their forecast at mid day today say it'll be around 1036 so we do have high pressure over UK presently. But I will hopefully connect laptop again later and compare the readings and get screen shot of the test page too.

Re. Battery voltage. I totally agree with you about that. When I connected my laptop yesterday to the bike I rigged up a spare car battery onto the bike battery to make sure it won't loose voltage. I also have the bike lights off. I was concerned that the voltage maybe too high when the engine was running. If you look at my 6 TuneECU screen shots you'll notice the voltage in the bottom left corner fluctuates between 14.2 - 15.3 volts which I think is unusual and I can't believe the TuneECU readout is accurate! In order to check this I'll connect my multi-meter to the battery when I next connect up to the bike to compare readings.
Title: Re: Fuel pump problem 2005 Girly
Post by: Fross on December 30, 2014, 12:34:01 PM
Hi BB, I've searched/read your article about "adaptive tune" instead of the "12 minute tune" and found it interesting. I have performed the "12 minute tune" on a few occasions since I've owned my Tiger and always believed it improved the bikes running. Have I been fooling myself?

The way my bike is running presently I will not be able to follow the "adaptive tune" procedure, because once the engine has reached temperature and I blip the throttle to 3k revs it will just stall when the engine revs come back down.

I've now downloaded from the TuneECU site the 10173 map you suggest, I'll give it a try, I presume I then need to carry out a TPS reset, wish me luck.

"Also, can you get a screen shot of the test page as well?  Need to look at the IACV steps and the idle fuel trim"
I can start the engine first to get this, but does it make a difference if I load a new map etc. with a bike that's already warmed up?

Engine doesn't need to be running for those readings, just take a shot of what they read when you turn it on.  The steps fluctuate anyway so was just interested to se the last stored value.
Title: Re: Fuel pump problem 2005 Girly
Post by: Fross on December 30, 2014, 04:03:56 PM
UPDATE
I connected up laptop and loaded the 10173 map. All OK. I reset TPS following these instructions:-

1. In the Test mode, double-click Reset TPS.
2. Turn off the ignition.
3. Turn on the ignition.
4. Start the engine and let it idle for one minute without touching the throttle.

I let the engine run without touching the throttle till the fan came on (running fine all the while). Then blipped the throttle it picked up clean and sounded great. My instant reaction was  :eusa_dance"great it's fixed" I blipped it again and disaster  :BangHead no pickup it just miss fired and spluttered to a stall. I looked at the laptop and saw the error code:-

P0122 Throttle position sensor low voltage (short to ground or open circuit)

I started the engine again and watched the TPS gauge in the TuneECU screen as I opened the throttle the engine misfired and stalled but the gauge did not move. I twisted the throttle wide open and realise it doesn't read until wide open starting at 40% and reading 79% when full open. I was getting no gauge reading when opening the throttle about the first ΒΌ turn.
It all makes sense, that's why its been running perfectly each time it starts from cold, only goes wrong when I touch the throttle, because the sensor doesn't know the throttle is being opened. Seems to me I need a new TPS. Please let me know what you think? Hopefully it's a  :thumbsup

When I order a new TPS I also need to order a new electrical connector for the fuel pump. Does anyone know if these are available separately? I'm guessing they only come with the loom?
Title: Re: Fuel pump problem 2005 Girly
Post by: John Stenhouse on December 30, 2014, 04:14:08 PM
Well it makes sense to me. By the way the value for flat out is correct it seems they don't go to 100% only 70 to 80.

I've just been looking at the TPS from below the tank, until I get the tank off I can't tell for sure but it looks very close to the frame tube. Can anyone say whether it can be removed without having to remove the throttle bodies first? :icon_scratch:
Title: Re: Fuel pump problem 2005 Girly
Post by: Bixxer Bob on December 30, 2014, 11:38:07 PM
Nope, the TBs have to come off.  So you're now into another little project.  Look in the stickies for my "How To" on changing the TPS.  You'll need a new throttle body gasket and while you're doing it it's a good idea to replace the chocolate torx screws with stainless steel allen bolts.  If I remember right, I put the sizes in the sticky.

I find the TPS reading lags a bit sometimes so make double sure by just turning the ign on, not starting the bike, and slowly opening the throttle.  If you get the same result as just now you're on your way.  Good luck!  :thumbsup

BTW, I had a TPS fault years ago, but I only managed to find mine by using an occiloscope because it was failing rather than failed.
Title: Re: Fuel pump problem 2005 Girly
Post by: Fross on December 31, 2014, 12:14:26 PM
Thanks BB, I've now read your very helpful instructions. :icon_study: On your advice I hooked up again this morning to double check. The TPS meter read different today, it reads 7% with throttle shut. As soon as I start to move the twist grip it goes straight to zero. While twisting open very slowly, a couple of random numbers appear (e.g. 19, 26). Once at 40% position the increase is almost sequential all the way to 86% (higher reading than yesterdays full throttle). The same result (in reverse) when slowly returning the twist grip to its stop.
I did this several times with same result each time.
I erased the error code (P0122 Throttle position sensor) but it comes straight back.
I can't help wondering why this error message didn't appear until I loaded a different map and tried to reset the TPS? :icon_scratch:
Tried to call my local Triumph dealer this morning to see if they have what I need, but they must be closed today.
I will post here what happens once a new TPS is installed. :icon_salut:
Many thanks for everyones help.

The reason I asked you to try with the engine off is to eliminate the possibility that the laptop was taking time out from the readings to do other things then updating the display when it had finished.  It does look as though you have a damaged potentiometer track inside the TPS so, hopefully, you'll have it sorted when the new one is in place.

Regarding it not showing before,  my experience is that once the ECU has been upset by a low battery anything is possible.  My first experience of this was my local Triumph dealer doing a simple remap on my bike, before I knew anything of how these things work, and giving it back to me not running.  Hours of reading, deduction and some money for Tuneboy (TuneECU wasn't around then) and I'd worked out what was going on.  I took it in for a remap after fitting my Blueflame.  My battery was weak so the new map didn't take.  Confused by this the dealer tried valiantly to fix it by trying other maps but nothing worked properly so I was asked to take it home and book it in the following week for investigation.  The ride home was awful.  It wouldn't tick over and needed a big handful of revs to get  it to pull.  It was also very reluctant to start.  I took it back on the agreed date and the following day it was even worse, it wouldn't run at all and he showed me the injectors not firing.  I then started to learn about fuel injection.  To cut a long story short it turned out that a new battery and a remap got it running again. 

Due me not remembering as well as I used to it took me a while when confronted with similar symptoms recently to remember the injectors not firing was an indication of the battery / map problem.

Working on what I think is a similar issue here:

Note his video clip and mine sound very similar, except I know what was wrong with mine.

Just checked my readings today and with the engine off, in test mode TuneECU reads the TPS accurately from 1% to 78% (you never get 100%) so you seem to have nailed it.

I've uploaded a couple of screenshots for reference, ignore the difference in baro readings between Tuneboy and TuneECU, they are different units but are roughly the same.  You'll note that your O2 reading is rich compared with mine, in balance it should read 0.46v Rich would be 0.8-0.9v lean would be 0.05-0.1v  they generally read one of these three if they're working right.

I'm still waiting for the new TPS to arrive but had some time this morning so removed the throttle bodies. It wasn't difficult just fiddly, all the six screws came undone OK without damaging the Torx screw heads. Also the two 4mm TPS Torx screws came undone easy. I will replace the screws with Allen heads anyway and can confirm what's needed are six 6mm by 30mm screws for the throttle bodies and two 4mm by 25mm screws for the TPS. I think it'll be more difficult trying to get the bodies back on without damaging the new gasket, so great care and patience will be required. :icon_wink:

In the mean time, scrape the old gasket off.  Be careful to not let any go down the cylinder intakes (I blocked mine up with a ball of masking tape, sticky side out so anything tended to stick to it) and careful not to score the mating surfaces. I use the end of a 6" steel rule but then I come from a generation of machinists who considered the 6" rule to be the ultimate universal tool, long before Leatherman thought of it  :icon_mrgreen:

The masking tape idea is great. :eusa_clap I didn't use anything special to remove the old gasket, most of it pulled off, what was left I scraped away with my finger nails, then finally used a cloth with some brake cleaning solvent.
I've chased up my parts order and they've said I should receive them tomorrow. :thumbsup

Hi everyone, I finally got time to put the bike back together and it started and ran OK, revved up nicely but didn't idle.
I connected up my laptop and started TuneECU, reloaded the correct 10172map into my bike, double clicked "reset TPS" which as I understand resets the throttle closed (zero position). I started the engine and waited a few minutes to let it warm up without touching the throttle, then blipped the throttle and it picked up instantly coming back to a nice 1200 rpm. I then switched off the engine then switched the ignition back on (waited for TuneECU to reconnect) and watched the TPS gauge as I slowly opened and closed the twist grip. The gauge rose and then dropped as it should, only reaching 77% at full throttle and returning to 0% perfectly. I am yet to road test the bike but will post here when I have.
:wheel
In conclusion, I would suggest to anyone who suspects their TPS is faulty to carry out the simple TuneECU test.
Interestingly, when I took both my Transit van and my Kawasaki for their MOT's yesterday morning I happened to show the removed TPS (it was in my pocket) to my MOT man and he said it looks just like the ones fitted to some Ford Fiesta's. I wonder if the same item is used on many other vehicles?

In answer to is it fitted to other things, without a doubt.

Anyone remember the Toyota recall a few years ago about cars that took off by themselves? A mate works for them and said the part at fault was bought from a supplier from whom Toyota took 75% of their production. The other 25% went to other manufacturers........never saw any other re calls did we?

That has no relevance, sorry, glad it's fixed.

Happy New Year all.

It's an old thread but seems relevant. My 1999 886i Girly started up fine last week, but today, not a sound from the fuel pump after turning on the ignition...

Can anyone tell me where to find the connector block between the fuel pump and battery so I can check some voltages and clean the contacts? Is this a tank off job?

Thanks in advance for any help.

if I understand you correctly,

it is a seat off job, you will see the connector on the left side of the tank, close to fuel ports.
