Pulled the tank out to replace fuel couplings and fuel filter. Charged the battery, cleaned all connections etc.
Key in, dash lights on, fuel pump spun up....moment of truth....starter spins....no brrromm broom!!?? :?
Bike has been off road for about 3 wks while I waited for parts from US - Australia.
Yes there's petrol in the tank.
Please help.

since you had the tank off...try repowering the bike a few times in a row... IE trun on, let fuel pump do its thing, turn off and repeat. Then crank fro a while... it may just not be getting fuel.. or somehow you didn't get the fuel connectors reattached right??? just making guesses...
gooruck!
WELCOME to the site
check the stickys at the top of each forum they are full of information for the various tigers and topics
see this thread here tank removal (http://tigertriple.com/forum/index.php/msg,32393)
perhaps you have a vent line or fuel line hooked up backwards
something to check seeing how you had the tank off for awhile ..............
To eliminate the possible vent line mix up just open the filler cap. If there's a slight noise of a vacuum being filled as you do that, there's your problem, although it should have run for a few minutes to cause the vacuum before cutting out if this really is the problem. Next try to start her with the filler cap undone. If she runs that confirms it.
There's really nothing else tank related to cause this because if the pump winds up and then cuts out that proves the connectors are good and the fuel line is pressurising properly (if it wasn't you'd soon spot the fuel leak anyway). Any other mistakes would throw up an ECU fault but it would still start.
Oh, and the fuel couplings probably have one-way valves in them. you did install them the right way round, eh?
Thanks for the help guys. Man am I glad I found this site!
I've got the MIL illuminated (Malfunction Indicator Lamp). As I don't think the shop will let me borrow their diagnostic tool then I may have to buy my own. I'll have a listen with the petrol cap open.
Quote from: "Bixxer Bob"Oh, and the fuel couplings probably have one-way valves in them. you did install them the right way round, eh?
They don't have one-way valves just shut-offs (that is, apart from the Triumph replacement metal couplings that apparently don't have them so piss fuel everywhere when you take them off).
I can confirm they can go on either way round as I've had them both ways on mine (04) with no problems.
Just a couple of (unlikely) possibilities:
1. I once tried vainly to start mine until I realised it was in gear with the side stand down. It'll turn over with the clutch pulled in (which of course you always need to do) but won't fire.
2. Your bike may have a tip-over switch (under the seat). This may have been tripped.
3. Kill switch?
Quote from: "iansoady"3. Kill switch?
Pulled this one myself on a recent ride with others. Having never used the kill switch I didn't think of looking there when the bike wouldn't start. I must have brushed the switch while getting off the bike. Felt like a fool when a guy came over and pushed the switch and the old girl fired right up....
.. just a note that later model 955 Tigers only have one fuel connector... dam hard to get that one wrong... lol

Yep, I'll admit to flattening the battery on mine before I twigged that one, not long after I bought her
Actually the CPC fittings are sold either with valves that close when you disconnect the fittings, or without them. I have hooked up my fittings backwards before and the bike ran fine till I took the tank off the next time and discovered the problem. :shock:
The vent hoses on the other hand are different. one has a back flow valve, and the other one is straight tube.
Quote from: "EvilBetty"Actually the CPC fittings are sold either with valves that close when you disconnect the fittings, or without them.
True, but I understand the ones Triumph provide for the recall don't have the valves.
QuoteThe vent hoses on the other hand are different. one has a back flow valve, and the other one is straight tube.
Not all - mine doesn't.
Correct, the Triumph metal replacement male fittings are not valved.
The valve in the overflow / vent tube apparently is a rollover valve on newer Girlies.
ROLL OVER VALVE - US & CA ONLY SERIAL NUMBER 260568 AND HIGHER
I think "US & CA ONLY" may give us a clue........
Quote from: "iansoady"I think "US & CA ONLY" may give us a clue........
Mine has one in the vent line. black cylinder 2" long pipe in at top out at bottom
without it a lot of juice will spill out of that tube when the tiger takes a nap

OK! plug in the OBDII into bike and USB to my laptop. Freeware program installed and run "Scantool". DTCs (Diagnostic Trouble Codes) showing on ECM:
P0230 = Fuel Pump Primary Circuit
P0463 = Fuel Level "A" Sensor High
P1231 = Open cct or short cct to earth
P1611 = Low level fuel indicator lamp short cct to earth / open cct
Ok so found that for some reason there was a melt down in wires on the plastic connector from the alternator to the rectifier - nasty. Changed that, re-run OBDII no P1611, other codes still apparent.
I have 12V on fuel pump plug when IGN is on and it spins up to pressurise to 3bar (guessing that's the pressure without a guage).
Trying to trouble shoot with reference to the service manual, it's really difficult to trace wires for continuity with-out pulling apart the wiring loom??
I've made sure that the metal fuel couplings are not blocked by depressing the valves inside and on the plugs - petrol is expelled.
Any ideas PLEASE!!!
:?
From the Tiger manual:
P0230 = Fuel Pump Relay Fault
P0463 = Fuel Sensor High Input
P1231 = Fuel Pump Relay Open Circuit
P1611 = Low level fuel indicator lamp short cct to earth / open cct
I'd ignore the fuel level ones. However, the fuel pump ones will stop it starting. Are these stored DTCs or current ones?
Most of the bits & pieces are permanently live (eg the injectors) and the earth is switched by the ECU. A cursory look at the circuit diagram indicates the same is true of the fuel pump, so merely seeing a voltage at it won't tell you anything useful.
I suppose you could check whether the pump is running by detaching the top (return) connector from the tank and see whether fuel is pumped through but I would be very very careful about doing this. In fact personally I wouldn't.
Thanks Ian,
Yes DTCs are new not stored. I cleared them and they came up again.
The service manual warns not to disconnect any fuel lines while in operation - I will heed this advice, don't need anymore problems.
Also took the RH side of the fuel line, there's a big o-ring sealing it in. Checked that there were no blockages. Checked all the fuel hoses for blockage.
Is there any chance of air bubble blockages?
The bike doesn't even seem to gurgle when I turn it over, can smell fuel from exhaust pipe.
Just had a look at my Haynes book of lies wiring diagrams, and all the injected Tigers, with or without fuel pump relays, have supplies connecting to the alarm connector block - a well known source of electrical gremlins. I'd check you've not got any corrosion in that area, it's under the tail cover.
Have you checked that the relay hasn't given up on you? Put 12v across pins 4 and 6 and it should audibly click and close the circuit across pins 1 and 8 (don't ask me why they aren't just labelled 1,2,3 and 4)...
cheers bixxer bob. I've checked the alarm unit and all seems ok. I've been studying my wiring schematic aswell. Bike has been off the road since a few weeks before Easter!
No relay on my Girly for fuel pump. Could it be to do with the fuel pressure regulator? I've pulled the tank out again and it's getting de-moralising. :(
I just re-read the thread and noticed that you've checked the pump works and that you can smell fuel in the exhaust, so we can assume the fuel is getting through.
Have you checked your plugs are sparking? I'm assuming you've not disturbed them...... but if you've got fuel, there has to be another reason for no start. It's hard to fault find without being hands on :roll:
IT'S WORKING!! :P
Realised that when I replaced the handle bars with pro-taper bars the throttle didn't seem right and when I hooked up the diagnostic tool the throttle was reading at 39% open.
I dismantled the RH instrument cluster and released the cable. Tank back in and BROOOOOOM!!! She purred away like nothing was wrong! I was ecstatic!
The only problem I have is the little 'o' rings i bought are a few mm too large and won't seal the quick couplings so have to find the right ones.
So the Tiger won't start if the throttle is open.
Thanks to everyone for your help!
Matt :oops:
Glad it's done. The manual says don't touch the throttle when starting and explains that if you do, the ECM may misinterpret where the closed throttle position is but, if I recall correctly, it doesn't say it won't start. Nevertheless, it's one to chalk down in the knowledge base; it's certainly a new one on me although, to be fair, if we'd known about you changing the bars as well.... :roll:
Go ride and enjoy!! :lol:
As always, if it won't start but was running perfectly previously, start by looking at what you've done in between.
You're lucky it didn't jam when you were riding......
I suspect if the throttle's open when you're trying to start the ecu will supply too much fuel as it'll be looking at throttle position - the opposite of clearing a rich mixture on a carbed bike by kicking it over with the throttle wide.
The handbook does suggest that in very cold conditions starting may be easier with the throttle open a bit which supports this view.

Autozone has some Viton o-rings in a variety pack in the HELP! section. 2 of them will fit the fittings like a glove. I think they rings themselves were a color other than black.

yes indeed most home mechanic problems are self inflicted , in the old days of my 67 bonneville whenever it would malfunction I would always look at the last repair or item I messed with and the problem would be at hand ..........
