Cheers mate, I didn't realise there was a fuel pump ecu as well, I'm having problems with the alarm in my car shutting off the fuel pump, at least I'm pretty sure its the alarm anyway.
Basically I can sometimes start the car and it will run fine untill I switch it off, but other times it will start and I can see the fuel damper with the screw on top die down and the engine will stop.
I know the alarm is faulty so I was assuming I hadn't disconnected all the immobilisers yet and was trying to find were else it had been wired to, but does that symptom sound like the fuel pump ecu to you guys?
Cheers
Ben
