Power coming out of where?

I wish you would go back to basics and do some voltage testing instead of jumping all over the place.

Use a test light on the negative side of the coil. While cranking, the test light should flash.

Okay, then the module and pick-up coil are good.

I have responded in minutes when you post.

The backfiring usually comes from the timing. Did you set the distributor on number 1 compression when you installed it?

I understand but if you have fuel and spark, the only thing left is either compression or timing. It is one of those 2 items.
