Yet another ECU question

Right the electronic ignition was put in by previous owner. I believe he took everything from a 75ish Valiant and swapped it in, which is why the dual ballast.

74 360 I will ground the ECU for sure.... the strange thing is the car dying in gear and then when I put everything back it magically worked...
what about putting the car in gear would change anything as far as ignition is concerned? Nothing[/QUOTE

Is it a column shift? I wonder if the ignition switch had been recently replaced and the wires were not fed through the column properly...getting rubbed/shorted when put in drive?
