Yeah well thats where im really stumped on this, i have checked continuity from injectors to ecu and thats allgood but when i spin the CAS by hand only the coils fire. Ive tested the signals from the CAS for the 1 and 120 degree signals and confirmed that is working correctly and even tested it at the actual pins on the ECU as well. The fuel pump is priming and i have checked that the lines are the right way round.
