I'm having trouble getting the Ford diagnostic computer to communicate with the PCM on a 2000 LS V6. The car was struck on the right front in an accident and everything mechanical/body has been repaired. The air bags on the steering column, passenger seatback and dash blew and have been replaced. The engine will not crank using the key but will start and run by jumping from the battery to the starter solenoid. We have followed all of the diagnostic procedures listed in the Ford shop manuals but can not get the diagnostic computer to communicate with the PCM. We have changed to another PCM and instrument cluster with the same result. There is a security light on which we can not cancel because we can not communicate with the PCM. Has anyone had a similar problem or do you have suggestions to solve this puzzle? Grateful for anything.
