THREAD LOCK ALL THE THINGS!
Guy from OMEX has obviously been very helpful. Odd how its working now. I guess a poor battery connection could have reduced power to the ECU when cranking?
Quote:Hi Sam,
I agree, this would imply there are two issues.
You said the fuel pump remains on when starting the car, does it continue to run when the starter is released and power to the ECU still on? Which cylinder(s) is filling with fuel?

Quote:Hi,
It appears you are powering off the ECU when your ignition switch is in the cranking position, a common fault is the ECU has been connected to an auxiliary pin of the ignition switch which loses connection when cranking.
I still don’t know why the injectors and fuel pump are turning on altogether, this would suggest the ECU has three internal faults. Have you checked the wiring harness for faults?
Would you like me to test the ECU for you? If you do decide to send it to us please include a letter explaining why you have sent it, return address and contact details.
