My buddies 86 just did that last week, and it was the ignition switch. There is a little arm on the inside that pushes the pins, and if one of the pins don't make contact, no ignition. My buddy at first thought it was the starter, but after I checked it out, it was the switch.If you need to know where to get one, I can call him and find out, he paid like $40 or $60 for it with 2 keys. It takes about 15 minutes to swap. PM me if interested.
