Of course. The pickup unit is what triggers the module to "make spark." You have "any other" magnetic distributor you can "alligator clip" in to test?

Does that Pro Comp thing have a pickup coil adjustment similar to the Mopars?

Also you said 'was working with Mopar 4 pin but weak spark'

The pickup WILL NOT cause a weak spark, but it could trigger intermittently, causing a miss or a "once in awhile" spark

What do you have for supply voltage?

How did you ground the HEI? Photo?

looks identical to the mopar stock distributor.... just a new unit by procomp with a mild curve in it. bought from summit, I did get it to run briefly with the 4 pin unit, but hasn't worked well at all lately, gave up on 4 pin. might have been the dizzy I guess...
I do have a stock unit, just worn out .. just plug in and spin it? should make coil spark on and off if center wire near grounded to see a spark of distributor?
