Can you give the year of ecm and motor
Zedn Can you give me the year or 8 digit number on the back of the ecu and the motor you are working on. I have full access to gm info. I am using a gto 2005. p0807doesn't show. there is only power wire in and out to ecm. There is a larger slot in the crankshaft to tell the sensor with #1 cylinder is either at TDC or 50 degrees before. You are going to get an high low voltage with the crankshaft sensor. Need this info for the correct diagnosis. The motor should also run with either camshaft sensor or crankshaft sensor disconnected and run in a backup mode. What is the fuel pressure?? Rick
