Logic would dictate the distributor cap has moisture or carbon-tracking inside it, or the rotor is shorted, but logic does not always pan out. Still, I would start with those before searching for more elusive causes. Also, check for the carbon brush in the center of the cap. If that wear down, the point can be reached when the spark will find an easier path to follow.

Did you change the coil wire? It could be shorted not getting the spark to the distributor.

Please let us know what happens.

Best, Ken
