Help No fuel pressure (FIXED)

[metalguru]

Help please guys, just completed head gasket replacent on my 885 tigger and went to start it and turned over real nice got oil pressure but no go. Further investigations revealled when ign is switched on the fuel pump will run for a short time and then stop. When the return fuel line was detached from the tank and ign switched on no fuel came out. Even held valve open in feed connector and switched on...Nothing. Any ideas please, thanks alot. Sorry forgot to say it's an 01 with 99 date stamped all over it, must have hung around a bit, and is, yellow with an open standard can and remapped to suit.

Wasn't that what happened to Silver Tiger in Devon, he broke down on the road and an AA man diagnosed no fuel pump running.

I think he bypassed the relay and got it home like that. Seem to remeber that it was an ECU fault.

If your hearing the pump run when you turn the key on though that would sound like it's working, but you would think that you'd have fuel spitting from your connector.

FYI, once when working on mine I connected the lines backwards and ran that way for a day or two.  Bike ran normal.

Everything else I can guess at wouldn't make since (fuel filter clogged, etc.) for the work you performed.  Might be worth opening up the fuel pump plate though and making sure all the lines are connected to the pump and filter.

I've never had my TB's or fuel rail off to see if anything else might have caused your problem during reassembly.

Thats what has baffled me, it was working fine when I rode it into the w/shop, carried out work on an unrelated part, the tank stood for about 1 day. Can the connectors mess up in 1 day? Tried changing the conns around, even opened the tank conn valve manually expecting to get soaked in arabs finest but nothing. Let you know what transpires. If it is of interest the reason for doing the head gasket was that a former 'engineer' that had the bike put at least 1/2 to 3/4 litre too much oil in it and when ridden in a 'sporting' manner it blew oil out from head gasket. now back together with Yamabond. Expensive yes but well worth it as I used to build engines with it and never had a casing leak.

YAHOO sucess, took the tank off yet again and removed the pump housing found the delivery pipe had blown off the filter????? Why it should happen now is questionable butb in a way good that it did and not on the way to somewhere. Hope my findings are useful to other guys out there.
Many thanks for your help.

Glad that was all it was. Isn't there a clip to hold it on?

Yes there is the standard clip that holds all the pipes in place but after last adventure might be good to replace with stainless worm drive clips. Considering only 3 bar pressure these 'should' be sufficient. Food for future mod I think. By the way have fitted 100/90 H4 lamps so not only can I be heard but seen aswell. Headlamp beams are much improved for the cost of £10 the pair from ebay.
