20let help

[chris gsi]

Finally got to the stage to start my car and it won't start.:cry:

The story is its a c20let conversion in a mk1 1.2 shell, if it makes any difference. I have followed the wiring guide in the article section and the fault I'm getting is no spark and no injector feed. I have been through the loom and have checked the 12v feeds to the ecu, the switched feed and checked the earths and all seem good. I have fitted a new coil and fitted a good crank sensor and still no joy. I have an ebay fuel pump relay fitted and the pump just runs when the ingition is turned on-I'm sure it's ment to prime and then run when the engine is running. Would a dodgy relay cause the fault, of it not starting?

thanks chris

Is the pump working when cranking? Can't remember which engines but some Vauxhall's prime when you put the ignition on some only work when cranking/engine running. Been a while but on XE/LET isn't it possible to get the knock sensor and another sensor poss ICV plugged in the wrong way round.

Shouldnt run with igntion on the relay on them does ecu and fuel pump and a comon fault for failing id be trying that first. Pumps dont prime on let,s wen igntions on either they just stanrt wen cranking

Thanks for the replys,I rember getting the knock and icv round the wrong way before dave but unfortunately made no difference. I also changed the distrubtor as I had a spare new one still no joy,I will order a fuel relay from work on Monday just to rule that out

I believe I have found the problem, the loom from the crank sensor has fallen apart ��
