I've got a 91 ranger with a 2.3 in it. I can't get spark from #2 & 3 on the lower coil. Have switched the coils around and the problem stays at the lower coil. The top one is firing on all 4 with both coils. Have pulled the Ignition Control Module off and had it tested, they tested it 3 times and it passed each time. The truck doesn't run rough and has good power, but I'm just trying to figure out why there is not spark on the 2 plugs of the lower coil. Any thoughts or ideas of what to look for?
