Sorry it took me so long to respond, I had to travel 5 days and 5 nights by mule to get to the nearest town that has electricity and inter net....J/K
I had that problem too, I cleaned, checked and retightened the ground from the battery and engine block, changed the cam sensor, removed and tested the alternator (good), jiggled the ignition switch and key release lever, reset the factory alarm, checked all the plugs, tested and changed the starter-relay switch, and it didn't even crank.
Have you tried to remove the aftermarket alarm if you have one viperman27 ? Mine had a hot spot that melted the harness a bit and that caused a wire from the A/C to get hot and melted through the casing and ground to the car.
If that was the exact prob, I don't know, but it starts now. I was supervising the work and there was a grounded out wire from the A/C that was bypassed and replaced and it runs now and Gerald is my friend again...LOL
Keep us informed.....GL
