Continuing to track down source of no voltage to coil while cranking

The path. According to my diagram, J3 comes off the coil, goes through connector CE-37, then branches off three ways

One branch goes to the ballast, One goes up to (I can't read) either CE30 or CE39, the starter interlock switch, but that goes TO it it is not series broken there. One continues to CI38, the seat belt interlock box under the dash but it goes TO that and is not series broken
branches off and continues, finally, to CI-1, the ignition switch connector.

So it seems to me you are fighting a bad connector, most likely either ignition switch, bulkhead connector,

NOTE THAT THE PREVIOUS MENTIONED CE-37 IS THE MUCH DREADED ignition harness connector, normally white, in the engine bay that separates the engine from the rest of the underhood harness. Member Redfish has pointed out a number of times that THESE ARE TROUBLE
