Re: Coils 1 & 4 not sparking
Try a new power transistor, and if thats not it your going to have to trace the signal wire that signals the coil to fire which should be a red wire. Check from the coil back to the ecu for any problems. Then check the pin out on the ecu for coil 1 and 4 and if theres nothing there your ecu is the problem.
