Hey Nash
thanks for the reply. I failed to mention it but I did indeed try that. I got the new coil and it fired right up on all 4. All good now! Bad luck i guess with the 3 test coils I had must not be good either. I removed the pins from the connector and taped the exposed wires just in case the signal was somehow arcing to the other exposed wires.
Success!
getting down to the nitty gritty. bypassed the main harness with new wires and i’m getting signal directly out of the ecu on the test lead and also through the main harness at the connector to verify the wire wasn’t bad, tried swapping the coil to another cylinder again and it’s not firing. I think conclusion is coil pack. I’ve ordered a new one and will update on Friday! The most recent video about ignition coil testing showed using the led test light, this helped me verify the signal wire was indeed firing off. instead of firing the parts cannon, i’m firing the tools cannon! thanks Matt!
I’ve also ordered new connectors and wire leads to redo the ignition harness to repair the exposed ends.
Hey guys. Thanks for the replies. Kind of forgot about the place. Opps.
Still having this issue but it’s getting more weird.
Correct, this is COP.
Ran through full fsm diagnostics and everything checks out. Continuity, coils have resistance “except 0 and infinity”. There are some exposed coil plug wires but appear to be in good condition. Tried the wiggle and nothing changed.unplugged while running to verify spark and no change.
The weird part is the only coil not firing is the #2. If I moved the coil to another cylinder it works fine. The #2 plug looks ok, continuity on the wires looks good, new crank/cam sensors. Their wiring looks good and checks out.I’m at a total loss why only the #2 would not fire. It uses a common grounding circuit for all of the coils through the ECU so if the sensor or ground were damaged none of them would fire. I thought it may come down to the ECU but I had a spare and tried it and #2 remains elusive. Gonna start looking at harness repair, try to run new leads and see if maybe they are indeed damaged.
Any other ideas greatly appreciated.
