Is it possible that a dead battery, even on a jump, would not have the proper voltages to make the PCM function. Still have the crank wont start problem. Have replaced the Crank Position sensor, still no spark; I have voltage measurements on the sensor connector. The engine quit while driving and has never restarted.

Problems with the vehicle electronics generally begin to show when system drops below 9 volts. Check your volt meter while craning the engine to see if that may be your problem.

It is below 9 volts with the key in the start position without cranking. So are you saying while jumping the car could still not get enough voltage to the computers and not allow spark to happen?
