Hard starting assistance please.

It SEEMS that the distributor may be the culprit after a day of troubleshooting. After fixing those wiring issues, I bench tested two different coils I had been using. Both of them were in good operating condition. Have good power going to the engine bay from the trunk mount battery. Somewhere from the distributor to the coil, there is a significant loss in power. The coil shoots out 1 single weak spark on crank and that’s it. I ordered an HEI distributor from speedway for old Chrysler small block. I hate throwing money at a problem, but it the only thing left in this equation.
