I have an 84 ramcharger, I had it started and it just died and now it will turn over but won't start I replaced the coil, balistor resistor, and the ignition module, and the pickup coil. Could it be the whole distributor that needs to be replaced?

yes, it often is that IF that's the problem. Do try this video testing though https://www.youtube.com/watch?v=064Ilsz8Fzg

It wasn't the distributor put a new one in and till turn over but no fire.
