1964 Valiant HEI troubles

Have you measured continuity of pickup coil to be about 300 Ohms?

Is gap set to 0.008" to 0.010" using non magnetic feeler?

Check all connection locations including grounds and continuity with meter.
Are you getting 12V at coil for crank and run positions?

If you remove module connection "C" from coil negative, then ground coil (-) very briefly to ground and release do you get shocked or get spark? :)

If your base plate is aluminum, the anodize may be preventing a good ground at module.
