i have a 91 that did that and im sure it was a short in the wiring harness...
to fix all i did was cut the solid black wire comming out of the coil\igniter and the solid black wire coming out of the tach... wire the two up and it should work unless your tach is messed up ...im also going to rewire my whole truck front to back so thats just a temp fix so i could set the timing....good luck
