HELP

Hi mycar has been off the road for a while, i generally turn her over twice a week. Stupidly ive failed to notice how low she was on fuel lol - how this was possible with an impreza i dont know? Anyways, i know think the fuel pump (walbro only installed recently) has gone pop as no fuel is being pumped around the car. Is there any advice as to what i can do, whether theres anyway of saving the new pump, could it be that the filter on the pump has got loaded with sedement from the bottom of the engine or is there a chance that the pump has seized? Im hoping or good luck as i havent had any yet with this car Regards Gareth

Re: HELP

Check the relay too and try your old standard pump to rule out the new one

Hi shambles, I haven't checked the relay will do, sadly disgarded the old pump as was original. Weird, car ran perfect last weekend, however this wkend just passed didn't wanna play? I have to admit, I installed a fuel pressure reg but removed this straight away when car didn't start, which makes me think pumps seized?

Hi bugeye, tbh I can't hear the pump, although didn't listen out for it? I removed the immobiliser last year in prep for installing thatcham system, this was by-passed by a specialist mechanic so wouldn't think this wld be the issue although I will check. I heard that its not wise to allow the fuel levels in impreza's to drop below qtr of a tank otherwise the pumps can seize? How true this is mind? Regards Gareth

Re: HELP

they dont seize(not sure where you have read that) but they do suffer from fuel surge/pick up issues at lower then quarter of a tank but thats when your on it and the fuel is splashing from side to side, when sat idle it wont make any difference.

Re: HELP

That's positive news about the pump not seizing. I have put ample amounts of fuel back in the tank so I know there's fuel in there now. Could the lack of fuel getting to the filter be down to a large air lock possibly? Regards Gareth

Re: HELP

Hi checked fuses none have broken, just out of interest, if it were a relay problem which relay is it for the pump? Also which fuse is it, I don't seem to have a manual? Any other suggestions, former owner said that with the walbro pumps, the hose from the filter on the pump can sometimes come away from the pump, not sure what he meant really but guess will have to get the pump bk out and see?

are you definatly sure its fuel pump? one quick check is to take hose off fuel filter under bonnet and turn ignition on, make sure a friend holds hose into bucket or something, this will show if fuel is moving about, worth trying before digging pump out

Hi wodoo, that was the first thing I tried, no fuel coming through? This has happened before, prev occasion was immobiliser, however removed immobiliser so cannot be this. Also prev occasion the connection plugs melted through poor connectivity so had to wire feed direct to pump. This has worked fine for the past 12 months the cars been off the road? Regs Gareth

Re: HELP

I think its the sock filter that fits on the end of the pump (the pick up filter) it could have came loose and came off did you use your original one off the subaru as heard that they better than the walbro ones JollyGreenMonster.co.uk

Re: HELP

Hi guys,

The saga continues! ve pulled the pump ot tested positive feed, my live feed screwdriver tool lights up when ignition is on, but doesnt stay on, i presume this is right? The pump isnt making any noises at all? The sock filter was the walbro one, however fitted correctly and hadnt come loose? One other thing it might be worth mentioning is that i fitted a fuel pressure reg on the front of the car, i spoke to a scooby owner at the Bulldog rally last weekend who said that if the pressure isnt set as to the same as something (he did tell me what, but cant remember) then the engine cuts out? Im not sure thats relevant in this case as im certain that the pum is cream crackered as they say. Any suggestions as to the fuel pressure regulator bit? Also anyone know of any good pump reconditioners as like i say this walbro pumps hasnt even been used on the open road yet!!!! Cheers Gareth
