hi, i am doing a vr6 coversion into my mk2 but it won't start,was running in donor car(92/93 vr6).i paid tsr to convert engine loom as it has gone in a 1988 mk2 and i wired it up as per their instructions.i got power to ecu(constant and ign. on live) and is now earthed direct to battery, but i still haven't got power to puel pump relay.Are ecu's known to go down? any idea's would be useful.
