I'm gonna take a stab and say you're ignition system was replaced sometime in the mid to late 70s or 80s using parts from a "donor" or junkyard car. It does not appear to be one of the early DC kits or it would have had a solid state fixed Voltage regulator, and a 2 pin ballast. All that said, they still operate (and diagnose) basically the same. Not to sound silly, but have you grounded the case to the ECM ?I see yours is mounted on fenderwell. Tried a different ECM?
NAPA TP51 or similar, doesn't matter just to see if it works. I always have a spare.
Good luck, and look up a troubleshooting guide for electronic ignition, they are quite easy to troubleshoot.
