93 Ramcharger suddenly died

Check the wire to the crank sensor. You say you changed the coil, it's quite possible the one you got took a crap, maybe try the old one if you still have it, if it was working.

It seems to me there were some issues with some of the coils that were being sold, cheap Chinese junk or something like that.

It could be the comp, but I would certainly check everything else first. Computer will be pricey, I had to eventually replace the one in the van and by the time I bought it, had it flashed it was about 500 bucks.
