Re: Ignition system
The ignition module and coil are the only parts needed to produce spark. The ECM does not even need to be installed to have spark.
Where are you testing for spark? At the coil? At the coil wire? At the spark plug? If you are checking at the lug, check at the coil (wire), if you get spark at the coil wire, replace your cap, the button will likely be missing or extremely worn if that test pans out.
If you still have no spark, replace the coil, and/or check the signal between the ICM and the coil, the pink wire should have 12V on it, and the white will be a series of ground pulses (resting at 12V), that will charge the coil.
