Are you loosing spark? If you are, I need you to remove the 14 pin connector to the single module engine controler (SMEC) (with key off) and check all pins but specifically pin 12 and 14 to make sure they are not corroded and or bent. Chances are the smec is bad and causing this.
If it looks good, remove the coil positive terminal and connect a jumper from the battery to the positive on the coil. Momentarily ground pin 12 to produce spark.
If spark is produced, replace the SMEC. If there is no spark, use a jumper to ground the coil neg. If no spark is produced, either you have a broken wire in the harness or the coil is bad. I have a feeling the SMEC is the cause of the problem.
Let me know what you find.
