I replaced the coil, ICM, spark plugs, starter, and battery but cannot get spark from the coil.
I measure 12v at the coil and 12v at the ICM, the engine turns over great but no combustion / spark.
All fuses good, lots of power to interior lights / gauges. Can't figure it out. Please help before I freeze out here in MT with no wheels!

Does your vehicle have a single coil? If you have a distributor, have you checked to make sure the rotor is turning when the engine is cranked?

Sorry, it's been a while since 96 and I can't remember the exact set up.
