bump for help please

bob269

same thing has happened to my 94 wrx sti. It splutters now and then as if its about to kick in.

I've cleaned the cam sensor but still no difference.


Maybe somebody out there can solve both our problems

mine wont even splutter!

ive tryed the old ecu in it (im running the same ecu as standard but with a scoobyecu in it so i have a spare) but no joy.

ive checked the fuses next to the battery and ive checked the fuses in the box in the drivers footwell. it there a seperate fuse for the fuel pump?

Try squirting abit of cold start in to the intake as the engines turning over, it may give it the kick it need to get it started. Mine has the same problem and starts by doing this then once its warm will start first time I think it's the water temp sender thats at fault I need to get a new one and try it.
Let me know how it goes

bob269

You can tell if the fuel pump is working it should make a slight buzzing/clicking/whirring sound when you switch the ignition on.

I'd say fuel pump, same symptoms happened with mine and turned out to be pump

Is the check engine staying on? If so check what error code the ecu is giving out, this way you'll know exactly what sensor is faulty. http://www.saxonfields.freeserve.co.uk

bob269

The light stays on mine but it aint flashing any codes up

I've also got this light staying on if anybody knows what it means, (sorry for the crude drawing)

bob269

Happened to me a few months back however it was just the power to the fuel pump connection, this is located under the back seat on the driver side, if you need to get to the pump there are access panels in the boot. (thanks to the guys on here that helped sort that problem quickly)

ryn004

It won't flash any codes unless you conenct the read memory connectors:
1. Turn ignition OFF
2. Connect read memory connectors (jumper 5) [black connectors]
3.Turn ignition ON (Engine OFF)
4. Engine Check lamp turns on
5. Code is indicated by Pulsing lamp
6. If Code is OK then Turn ignition OFF & Disconnect Connectors
7. Check ECU Code
8.Turn ignition OFF & Disconnect Connectors
9. If there is a fault Check Appropriate Sensor

ryn004

By the way the connectors are found beneath the dash near the drivers footwell. More info on: http://www.saxonfields.freeserve.co....iag%20Page.htm

bob269

Thanks, i'll give it a go

i have that and check engine light but not a falshing one. if i turn the car over and then release the ket so the ignition is still on the battery, engine and that pic you drew is on. i think they all do it?

as for the fuel pump ill have a look tonight. did you mean just the connection or does it have a seperate fuse or a trip switch?

also if the fump has gone wouldnt it have given me signs before this?

bob269

Theres a spade connector going in to block which joins the fuel pump under the back seat, this was arcing out on mine. It's worth checking this before you get a new pump.

I had a couple of instances where it wouldnt start first time, then one day it just wouldnt start at all.

This was my original post, the guys on here pointed me in the right direction very quickly

Looking at the photo on that site it's showing 2 black plugs, do you just plug these together?

ryn004

yep. there should also be a set of green conectors i nteh same area. The green ones will be used when you come to reset the ecu.

bob269

Just tried it and got a constant flashing light which i assume means the ecu is reporting no errors, so i'm back to square one

There is fuel getting to the engine btw.

ive removed the rear seats and removed the covers on both sides. ive had the misses turn the ignition on so i can sit in the back and listen to the fuel pump. i cant hear a thing. i dissarmed the immobiliser turned the key once, couldnt hear anything. then turned the key again, couldnt hear anything at all. either its my pump or its a wire leading to it. im having a mate come round asap with his multimeter.

wah

Geez mate you not having much luck

I had the same problem with my95 wrx wagon..I dont quiet know it this was the solution or if it was just a coincidence but i connected the green connections up under the steering and turned the ignition on...left it for 15 seconds or so, then turned ignition off, disconnected the green connections and she cranked over and that was that

there is power going to the pump as ive checked tonight so i think its the pump thats had it

take the out let pipe of the fuel filter crank the engine over to see if fuel comes out

if no try the other side if the filter if not

try the fuel pump itself if not

it must be your pump or a feed to the pump


REMEMBER TO DO THIS WHILE U ARE NOT SMOKING !!!!!!!!!!!
