No spark at leading coil but do at trailing coil
 

Hey guys I’ve been looking through the forums for days and can’t seem to find anything on my problem. I don’t know if anyones on here still active. But I am getting spark from my trailing coils but not my leading. Checked the spark plugs, wires and all good. I checked the ohms for both coils and the distributor and they were within the FSM specs.

I did redo my main grounds. I redid the ground to the ECU to engine as well as the battery ground and power wires and then this problem occurred. So if someone can help me that would be awesome!

does the leading coil get power? sometimes the harness is a little tight and it can pull the plug apart too

yea i get 12v at the black and yellow wire

Swap in a known good coil? If your voltage is good, wires are good, and plugs are good, that points to the coil being bad
