Electronic ignition confusion

1970 Barracuda slant six

After removing the new M Perf distribuitor to replace a early 60's distribuitor hold down with a later model. It will not fire, we had set the timing at 32 total advance and it ran great prior to this endeavor. I have repaced ignition switch spliced new connectors at the column to dash harnesses. new engine and forward light harness new coil new ECU, dual ballast res and swapped a known good distribuitor. Sometimes it will spark when the key is turned to the on position and then again when it is turned off. when the switch is turned to the start position we lose voltage at the ballast resistor on the (  I-1,, run?? side of the resistor. I think start is I-2 to the coil full 12v). When the switch is in the on position we have 12 + at the dual resistor and 7to 8 at the coil, We are totally baffeled  as it seems we have voltage where we should have.

check with a Ohm meter for coninuity across the 2 leads for the pick up coil in the dist & check the gap between coil & reluctor

We have checked the pickup coi for the proper resistance (400-600 ohms according to an old NAPA-Echlin service sheet) on both distribuitors and they appear to be good. Spin the distributor and they produce a signal.
