i cut the injector wire next to the ecu scart and put my one test lead in the live on the injector scart and the other on the wire coming out of the ecu where i cut it and i got 12v from the ecu as it was sending a earth out. and nothing coming down the loom. so the looms fine.

i'm stuck on what to do now i dont know if ive buggered it by fitting the wasted spark stuff as i never used it before i fitted the wasted spark stuff.

any advice
