Intermittent Ignition Issue [66 Valiant /6]

cudamark said
If you suspect the ignition switch is the problem with a no-crank situation, I pull the plug off the back of the switch and use a jumper wire between the BAT and IGN2 to see if it will now crank. If it will now, it's the ignition switch, if it still won't crank (or even click the starter relay) you have a problem further downstream....probably the relay or wiring connection between the ignition switch and the relay. The neutral safety switch or it's wiring is also a possibility.

I think it’s a switch issue because randomly, the car will go to the “start” position of the ignition and not crank. no click. no noise. do not pass go. Happens at the worst of times too. The first time it happened I took the ignition out of the keyhole, wiggled it around, and it started working again. Last night when it happened I let the car sit overnight (after being towed) and all of a sudden it started cranking again.
