Ive recently come across a wiring issue with my C20LET management loom, the fuel pump relay will not power the fuel pump. The relay is getting power as it should but has no ground actuation, so the live feed will not switch to ground, on terminal 3 on the ECU plug. Ive tested the loom twice now and found no fault, all is as it should be, even the screened earths. For those of you out there who done this type of conversion maybe able to help me. Ive had a new ECU and even had that tested, and thats ok, new fuel pump works ok in another car. ive looked aroun on the net, some say it maybe the crank sensor???????? but im not sure, can anyone please help me.
