Distributor blues..
Problem solved! Thanks everyone, you were right on the money.
I went out today to start the car when it was cold. It wouldn't start again.
So it seems it was a defective pickup coil. I didn't want to mess with the Accel, so I went out and got a new Mopar distributor. The car started right away. I let it warmup, shut it off, & repeated a few times. It's fine now.
It seems the people at Accel sent me back the same distributor I originally had problems with. I could see screw marks where they fixed the incorrect gap with the reluctor. So the gap was wrong, & the pickup was faulty to begin with. I guess I have to send the stupid thing back again.
