Hard starting assistance please.

It SEEMS that the distributor may be the culprit after a day of troubleshooting. 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.
Sorry this does not make sense

What EXACTLY is your test set up and how EXACTLY did you go about this?

Step by step you did what? You rigged a test gap at the coil wire? Did you use the coil wire or a different wire?

You cranked the engine by doing what?
What voltages did you check and how, exactly, when cranking?

Tell you what you must be 3? hours from me? I'm in N end of Idaho. If you want to call when you can get out there --does not have to be today--send me a PM and we'll set it up.
