went out to the car the day 94 wrx sti and it wouldnt start its just turning over its not firing no fault codes found either! it was sound last nite let it cool down and went out the day it just sounds dead

 

Maybe just damp around the points with the cold weather?

This happened to me a few times last winter on the freezing days and there was nothing at all wrong with the car. Had to turn it over for over a minute on one occasion before it would start, and another time I flattened the battery doing it.

Think it might be made worse by turning it over and letting the key off before it fires up properly. Both times it happened to me, that's what I had done.

Hope this is of some help.

 

its not even firing its just turning over cant even smell petrol does the fuel pump usually make a hissing sound

 

Yeah it will be turning over nice and healthy, but just not bursting into life?

 

Put the key in the ignition & turn it as far as you can just before cranking it over. Stick your head in the boot & you should hear the fuel pump buzzing/hissing (i.e: priming itself).

If there's no buzzing then fuel's not getting through as the fuel pump's not working. Run through the simple things first such as check fuse & give the fuel pump a little thump (if it is buzzing then could be a few reasons such as the filter's blocked, wiring, ecu playing up e.t.c).

 

the other nite i was out went round the garage and when i went back to the car it started but it was cutting out as soon as it fired it done this prob bout ten times then it eventually went took a couple o seconds to get goin as if it was struggling a we bit

 

cheers cushti any idea where the fuse for the pump is everything is in japanese its a nightmare! is it a in tank pump?

 

Yeah that sounds more like a fueling problem as Cushti said.

 

Yes, it's an in-tank pump but easy to get to & change (if you do need to change it then I'd put in a Walbro 255 which are only about £70 & an upgrade on the original). Just lift boot carpet & there is a plate with several screws to undo & it's under there.

Is the fuel pump buzzing with ignition turned on?

 

cheers terzoalan im goin to take run out to c if i can hear the fuel pump ill let you no in a couple o minutes

 

ye just checked the fuel pump not hearing it at all

 

check the fuses it is prob a 15amp fuse

 

fuel pump in the boot cushti got a big boot install massive sound system this is turning into a nightmare

 

just checked fuses there all fine is there a fuel pump relay anywhere

 

what alarm/immobiliser is in the car?

 

ye its a clifford alarm and immobiliser you need to type a code into the immobiliser when the ignition is on then all the lights come on when you do that then you start it

 

I don't know about relays or electrics at all but then I've never ever had an electrical problem with mine in 3 years (touch wood). I imagine there is a relay for it - do a search on here.

This is a total long shot but your big boot install may have loosened the wiring going to the pump. Your mentioned earlier that you went round the garage & managed to get it going after a couple of minutes - how was it running after it had got going?

 

it was running fine when i got it goin and when i got back to the house it was starting no bother yesterday it was fine today wouldnt start at all! when i got it goin i was pumping the throttle as it was splutering after a couple of seconds it cleared and was fine since then

 

what side of the boot is the fuel pump on

 

It's on the right side looking in from the back of the car.

 

This happend to me yesterday, ended up leaving the car at work over night.
got one of the lads to have a look at it yesterday, took the fuel line off next to the fuel pump and tired to crank the car to see if fuel was coming through, not a drop!
he said either my alarm is stoping the pump from working or the pump is nackered!
got to work thismorning tired the car and it fired up first time! god knows what happend! might try to get to the fuel pump and have a look at it!

just came back to the house there just by chance tryed to start the car and it started first time!!

 

there is an electrical connector under the back seat for the fuel pump../ they corrode.. sound just like your problem..

 

Also, the relay is under the dash bolted to the driver's side A-Pillar.
Mounted on a bracket holding 3 relays - the centre one (brown) is for the fuel pump.

Worth testing for live at the relay, and seeing if it's switching correctly.

 

thanks guys i will check it out after work the day!!

 

checked the plug under the back seat the day cant see any corrosion although 1 of the wires have been cut out and rejoined but it looks alright the relay seems to be fine the car itself was orite earlier on when i turned it off it wouldnt start again it just keeps firing and cutting out

 

If its hit and miss id be looking at the Alarm/Immobilizer, relay maybe sticking or on its way out,
Seems to work fine then after u had set the alarm it stopped working.

 

Mine had similar probs.

It would only just start then soon as the throttle was pressed it stalled.

A friend parked his up over night then nothing.

Both where fuel pumps.

Its a very easy change.

 

does anybody no where i could get the wiring with the 2 plugs that goes from the pump to the block conector at the top of the tank for a walbro pump

 

or the spade conectors for the block conectors
