Two things come to mind:
First is the ignition switch. It's bolted to the steering column under the dash area. The wiring may be loose or burned, or the switch could be out of adjustment, or worn out.
The other thing is the neutral safety switch. This could be the problem if you get normal operation after you jiggle the shifter or put it into Neutral instead of Park. If its that, the dash lights, etc. will still come on w/the key, but the engine won't turn over.
