| Ignition Module problems |
The "pcm"-pump control module located on the injection pump that is in charge of operating and coordinating pump operations fails after 30,000 to 40,000 miles. This causes the vehicle to stop running--no brakes or steering similar to ignition switch problem in other vehicles. Gm likes to get 1,400 to fix, after the tow. Thanks charles tomlin a better fix needs to be made here rather than installing another defective part. This problem happens in all the 6. 5 diesel motors.
