Wiring and PCM issues
2006 Cobalt SS S/C with a 2.0L Ecotec.
Bear with me, it is an absolute mess. To start off, the car was throwing multiple codes, evap sensor replaced, O2 sensor replace as well. -Still threw codes, followed wiring harness, found numerous wires that were shorted out (not receiving ~12volts). -Soldered and wrapped new sections of wires to PCM. Still throwing codes. -(Something happened, father is a mechanic, he found a loose wire to nowhere, closed circuit. Car went into I believe theft mode?) -No dash lights (Check engine light, brake light, etc.) except for the security light coming on when I turn the key on attempt to start car, nothing happens. Security light then turns off -Looked up how to do a security relearn. Attempted that. But the security light does not remain on, which leads me to believe problem is elsewhere. Maybe the PCM? -Changed PCM to a ZZP 1.0 PCM. -Car will still not turn over nor start, dash lights still out, minus the security light coming on only when key is turned on, goes off after a few seconds. -I have checked fuses have yet to find any bad ones. .. I am at wits end with this car, any advice on what to do would be greatly appreciated. |
double check ecu connectors are on tight and the fuse block is screwed down tight, could also have a ground loose somewhere.

Checked both, able to bypass crank sensor and start the car, still no dash lights |
Sorry to hijack post but I'm having similar issues. Dose any know where to buy a complete wiring harness? From PCM to all the sensors and connectors in engine.
