Need tech info on a Pacifica

bet my quarter on ignition switch. Seen it too many times and not just in Chrysler products either. Manually operated switches are always suspect, especially those high repetition switches. heck I had a GM here once ( Lumina I think ) that wouldn't start but would cycle the electric fuel pump on and off with the hazard flasher switch. Took a while to figure out this was a backward feed signaling a relay but the ignition switch was the culprit.
