Ran in the same thing with an 83 200x. In my case, the stator was bad. You could pull it behind something and it would crank, but no way you were going to kickstart it. Swappwed stator out and that fixed it. The old stator ohmed just like the specs said it should. Donno if this is your prob but something to think about.
