So.........I should be here writing about how I've just had new seimens injectors, a walbro and valve springs installed and now running 270rwkw and its sweeeeet! :biggthumpup:

Well it was for two days however today while cruising over to a mates house (and just cruising I was) my car decided to just die out of no where.

I pulled to the side of the road and tried to start it again, no go!

Now, I had let the fuel get lowish, the trip meter said I had 75km left......hang on maybe the new pump is sitting a little higher and there is no fuel getting to the pick up. So after getting some more fuel in a jerry and going back and filling up I tried to start it again. Bingo straight away it started, idled for 5 seconds then died again. hmmmmm tried to get it to start again for the next 5 mins but no go

The question I now would like to ask is - when I turn the ignition on, shouldnt I be able to hear the fuel pump whining, ready to start? I can't actually hear the pump at all, though when I first got the ute back I noticed that the walbro seemed noisier than the factory item.

I will ring the workshop who installed it tomorrow, but would like to know if my thinking is along the right lines.

btw. I have checked the fuel pump relay etc with my multi meter and it is fine so I can assume that power should be getting to the fuel pump.

any suggestions would be great

cheers

did you replace the fuel hoses when you changed the pump?

I think you're on the right track mate, get the pump checked out asap. Did you buy the pump yourself or did the workshop supply it too?

that is definately a lack of fuel supply causing the problem, check for faulty wiring, kinks in fuel hose both externally and internally, clogged fuel filter, pump failure

Hi guys thanks for the quick replies.

Judd, I had a workshop do the work so I'm not too sure exactly what they have done when installing.

Senna, The workshop supplied and fitted the pump. I was going to buy a pump myself, but decided to let them supply it to hopefully avoid something like this happening as I've heard theres a few non genuine pumps going around. I could have purchased one $80 or so cheaper but thought the warranty from the workshop was worth more!

ETM, yeah my gut feeling is that there is no fuel getting to the engine.

I have taken the tub out and was going to do some investigating, but dont have the time atm. I reckon its the pump though, only because I can't hear it priming up or anything when I turn on the ignition..............just not sure if I'm imagining hearing it before?

Oh btw, I've towed the car home, it will not start at all.............just in case you thought it was a temperamental prob.

Possibly a bad join on the wiring on the fuel pump, or incorrect (non submersible hose) hose fitted to the pump.

you can hear my walbro prime when I start it. The only reason I said about the hoses is that if you dont use submersible fuel hose it can bust.

Yeah thought it could be heard on start up.

I would think that the right hose has been used as it is a reputable workshop.

atm I'm thinking that it is either a faulty pump or as ratter said, a bad connection in the wiring somewhere.

I'll let you guys know when its sorted.

Lucky its not my daily!

Hey guys, all sorted. had the mechanic come over on tues night and we pulled the pump out and sure enough it was 'seized'. Picked up a new one tonight (free of charge of course) and installed it............and its all good again! Went for a strap, damn these things are good with a litlle bit of tuning haha!

thanks for the responses! This forum is a gold mine of information, even though I post very little I have been floating around reading them for the past 4 years and have learnt so much!

Cheers again!

.............now for some more mods

Cheers
