360LA Intermittent Issue
Update as of this afternoon..
Voltage at the coil is good in run and start, voltage to the ignition module is good, continuity in the wiring to the coil/distributor checks out also. I found some minor corrosion buildup on one contact of the ignition module that runs out the distributor pickup so I cleaned that off too.
After all that I had the same issue but it sounded more like it wanted to fire so I threw in the cheap backup module I had on the bench, fired first time. So maybe I just need to put in the effort of finding a good reliable unit before I go any further!
