I have the seats out at the moment as I was trying to find the demister box.

I haven't disturbed anything but have checked it's all plugged in correctly though.

I ran a 12v feed straight to the pump yesterday and the car started and ran for about 10 seconds then cut out. Is there a chance that if the ecu doesn't get a return signal from the pump it will shut the ignition/injection down?

It's a deeply irritating problem. I don't dislike electronics and am usually fairly good with them but this is really pi**ing me off now.

I have followed the fuel pump diagnostic part of the ecu manual but parts of it require the car to be running in order to establish there is a ground which I haven't been able to do obviously. Finally it says to check for 12v at the connector for the pump and if there's not one then reinstate the wire between pin 87 of the pump relay and the pump. Well I have done this but there is no point as the pin of the relay doesn't have 12v itself. Bizarrely the pin is not part of the earlier diagnostic checks but that seems to be 'a' if not 'the' problem.

Any advice would be massively appreciated otherwise it looks like the car will be off to a garage (which I can't afford) to troubleshoot. It's probably a waste of time sending it to anyone other than coupe/integrale specialists so labour costs will be stupid plus the cost of getting the car there!!

I've only had it back 3 weeks since the gearbox was rebuilt and to say I'm frustrated is a massive understatement.
