demon 340 wont start, no spark

If I have "crystal balled" this correctly, this is NOT the way to hook up Pertronix.

To repeat, I do not know of any Pertronix product that hooks to the Mopar distributor connector
It sounds like he soldered in the Mopar zigzag pull apart connector to connect the dist to the coil so he can seperate/unhook/pull the dist somewhere on down the line when needed (which is a smart plan). If that is correct then he is fine. just connect ign1 "run" and ign 2 "crank" together if using the Pertronix (no ballast) coil and run that power line to the coil positive primary terminal
