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.

Update... Took off both coils and switched them.. Working fine for two days do far..

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

so. replaced my CPS, still not firing. all my fuses are good. still crap.

so still no go on all 4 cylinders.... bad pcm? it came unplugged somehow.. plugged it back in and car ran great for 5 minutes.,.. but now when car is off sometimes clicks and my left trun signal blinks with the clicking...

so maybe its not my pcm that i unplugged.. what type of computer module is on the drivers side of the center console that controls some of my electronics??
