Ignition issue

He's measuring 1 volt at the coil negative - this is either grounded (factoring in a voltage drop at the module) or something wrong with the coil.

Stock Mopar modules weren't very sophisticated - they ground the coil by default and briefly un-ground it in response to a pulse from the distributor. It's possible some variants wait to ground the coil until the first pulse arrives, but if the car had one of those, you'd be seeing 12v at the coil negative terminal.
