I have replaced camshaft sensor. Crankshaft sensor. ECM replaced. Mass air sensor replaced. I'm getting the code still and now won't start at all.

Hello,

This could be a problem with the wiring or the connector going to the Camshaft Position Sensor (CMP). I have included in the diagrams below a troubleshooting flowchart on how to track down your vehicle's problem from the manufacturer. Please go through it and get to us with what you find out.

Thanks,
Alex

Hello again,

What you want to do is make sure that the wiring is away from your vehicle's ignition source. It should be shielded as well because it can pick up rf signals from the ignition coils as they collapse and falsely report this back to the Power-train Control Module (PCM) AKA, "computer".

Thanks,
Alex
