92 sc DOHC center two cylinders... replaced the coil that wasnt firing.. didnt resolve the issue. i know its that one because with out the plug wires connected there it doesnt spark. i checked ALL my fuses... but randomly it will start up and fire great but within 5 minutes goes to not firing... i was messsing with it one day pulled a wire off electricuted myself... then it worked for a week flawlessly! already replaced my ects too...also no check engine light i know the bulb works i just replaced it.. any ideas??

Remove the coils and module and clean the pad underneath the module and on the transmission. This is where it gets it's ground.

If you have further problems, suspect the Crankshaft Position Sensor. My 97 was doing almost the same things once.
