1995 Ford Thunderbird Question: no fire from two of four towers on coil pack
I have no fire from two of four towers on one of my coil packs. I did a test on the three wires that plug into it and the tan and green wire(with my 12 volt test light clip on positive battery terminal and probe end on the wire) does not flash but the tan and blue wire does I also checked the other coil pack wires and they both flash. I also checked for the positive wire and it shows ok on both. I went to the ignition module to check for the same signals on the tan+ wires and all are flashing except for the tan and green like on the coil pack. Thanks for your help so far. Do you have any insight on what to do next? - jdean
Well at this point, I would have to think you need an ignition module. You have tested the output ground to the coils and only one does not work. All of the tan/+ wires should have a common ground at the ignition module, so it cannot be a ground problem. Since you have checked for ground at the coil pack and right at the module connector and did not find any on the tan and green wire. It is very rare, but there are times when the wires break at the plug connector and it is under the wire insulation. so it is very hard to locate. If you verify that the wires from the ignition module to the coil pack is intact, then you will have to change the ignition module. If that does not solve your problem, then you have a unusual problem and we would have to get really deep into it. Good luck. - irvtech
