Just to let you guys know, I have finally solved the problem with my girlfriends 2002 Cruiser. It had run hot and warped the head. After rebuilding the head and putting things back together, It would not crank unless you un-plugged the cam sensor. Took it to a local dealer. They said the timing was off. They didn't know! Got it back from the dealer and it would crank (As soon as starter engaged) but when it came up to temperature it would cut off. When you tried to start it acted like the timing was off. Keep getting P40 code. Cam sensor circuitry. I had to change BOTH the cam sensor, and the crank sensor. Seems to be running fine now. So, in my opinion, if you change the cam sensor, always replace the crank sensor too. It will save you a lot of headaches!
Thanks for your support and suggestions!!!
