I have a 2003 Chevy Cavalier that has not ran in over a year due to anti theft system I believe. Everything seems to work as far as radio, door locks, key fob, etc.. But the car will not start. I used the procedure for the 10 min with key on but the lights on the dash never did go out but still stayed on, antitheft light. When I hook up a scan tool, Actron CP9580A, it tells me no modules present. I tested the grounds circuits at dlc and they where good. Also tested the circuit 1807 for continuity. From the C100 connector to the PCM resistance was 1 ohms so I am going to replace, splice, a section of the wiring from the pcm to the C100 connector. I had also previously replaced the PCM that was freshly programmed. No fuel pressure, engine turns over, compression on all cylinders 175, antitheft light always on solid. If I jump the relay I can get fuel pressure but still no start. Any ideas? I know if I get this thing going I want to disable the passlock for sure.
