  • Yes, I would look at the ignition control module. I had this problem 3 months ago and that was my answer.
  • Which side of the passenger side or driver? also when you get in and turn key to on position, the check engine light should be on, and when you start to crank it 1 sec later it should go off to verify your Crankshaft Position Sensor is working properly. coils for the left side is primary, ECM control driver side spark on and off at ramdom. everytime you do any replacement on truck please erase memory,or your still be running in memory code. I don't check this site much please let me know if you got this problem solve.
