This unit was a mess. I have pulled the engine harness and made repairs where needed. I have added grounds in needed areas. The new TMAP did fix the engine codes, its clear now. I still have a intermittent no fire. Cam/Crank pulse with is good back to ECM. This machine has had a RE-man ECM, New Coil, Ignition Module, Cam & Crank Sensors, Point to point OHM out of every pinned ECM to connector. Its been a real challenging machine. It will run perfect, multiple starts, turn it off, go for a start, crank.....no fire. Power control relay makes and energizes systems as it should. Any ideas would be great. I need a data patch cord so I can see what the ECM is missing.
