Sounds more like the ignition module or pick-up coil in the distributor. On the ignition coil there is a 2 wire connector that goes to the distributor. Unplug it from the coil and using a test light, have some one crank the engine, the white wire should flash, if not the module or pick-up coil is out, most likely the module. That old of a truck I would recommend doing the pick-up coil as well. The dist has to be removed to do the pick-up, but not the module. Here are instructions on how to change the ignition module and the pick up coil as well. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
