Well all the normal stuff appears to check out OK, I think Ross checked the fuel pump too.

The gaps in insulation on the wires of the CAS plug didn't fill me with a lot of confidence.. neither did the butchery at the ECU plug end!

ok well dat suck's well at least u know thow's bits work

well it's worth a try changing it over. see if u can find some1 with a spare loom and ecu.

if all good then u can buy with out worrying about wasting money.

what ever it is i think its some sort of electrical prob. just going to take time to work out

the pump was priming but i didnt check fuel pressure, dont have a gauge.

its just one of those fun electrical problems :rolleyes:

Shame about the fuel pressure test, I still think it is a poor earth with the FPCM (fuel pressure control module).

Especially if the looms have been butchered.

Solder/twist on a wire from the fuel pump earth to the body of the car and let me know what happens so i can sleep easier :P

bogan way of testing if fuel pressure is causing the problem (assuming theres plenty of flow from the pump) is to slowly clamp the return line with some pliers (fat ones so you dont damage the line) and see if it improves.

otherwise theres a fairly cheap fuel pressure gauge on just jap that'll come in handy more than you think. i'd lend you myne but some prick smashed it up

Well I dunno, I just resealed the four split wires and took the bigass battery outa my V8 to try but still no good.. I can't help but think we'v overlooked an important factor, when the keys are turned to 'power' in the ignition, u don't hear the fuel pump prime, or if it is, it's alot quieter. Back in the day(a few weeks ago) you would hear it buzz loudly for a good 4 or 5 seconds. What could this mean?

Oh, and it's got worse, Mike. A struggle to even start now.. :'(

I havnt tried swapping a working fuel pump in yet, knight. I also better stress the problem has taken the car from fine to unstartable in the space of 12minutes gentle running time. :s

It turns over and after 6ish seconds it starts coughing like it wants to start, a few secs later it might start and as Bubba said, runs like a tractor..

I would try pump. it sounds like it might not be getting fuel.

My stagea dose not like starting first time in the morning and i am shore its to do with low fuel pres. When i started it in the morning it would fire and run but run like it was missing or not getting enough fuel then stall. after i start it again or give it a rev it comes good.

So i have fitted a 040 and it is a little better but still run's bad for about 10 sec's before the rev's pick up. I have a hks fuel reg i will be fitting soon as 1 of the stock 1s might be bad

runs like a tractor maby it thinks its a sr lol

It could be the fuel pump itself or it could be the wiring the ECU to the FPCM.. the exposed copper near the ECU was worrying.. as was the exposed copper on the CAS wires..

How'd you go fixing the wires Jesse? I wouldn't bother chasing other things like actual fuel pump etc until you know the wiring is all good..

how did you fix the wire? just put tape over them? The thing you need to check is if the cover is cracked that the copper inside is not as well. If may look fine but use the multimeter to double check.

Again more than happy to help but with weather and stuff need to do it in a shed as we will remove alot of stuff from the car.
