Have you confirmed that your distributor is indeed rotating while you crank?

yes and it has power in and out
there is a single black ground wire by itself that plugs on to the distributor housing by a spade terminal, if this is dirty or fallen off
-no spark.

Given the distributor is grounded to the engine block, that can't cause what you suggest. In almost ever case, that black "ground wire" goes to a noise supression condensor on the fender which has zero effect on the car running.
Not if the bolt holding it in is tight.
Given the electonics are grounded in their own harness, the distributor body doesn't have to be grounded at all. Try this, you can pull the distributor OUT of the engine, unplug this "ground" you claim needs to be there and if you spin the distributor, you get spark. Go look at the wiring diagram if you don't believe me.
