6. Cylinder duster is now a 340 ignition issues wants to start when you let up on the key

You have to understand how Mopar ignition works

1....First, there is only one 12V switched source into the engine bay with the key in "run". This is the (unfused) IGN1 "ignition run" power comeing out of the bulkhead connector into the bay. This splits up, and feeds the VR, the ignition system (ballast), the alternator (blue) field 70 and later, and depending on year/ model, electric choke if used, and some smog doo dads in later years.

IT IS NORMAL for that power to go dead in START

2...So how does it start? The ignition switch has TWO switch contacts (2 circuits) that are momentary hot when the key is in "start." One, of course, is the usual (usually yellow) "start" wire, and the 2nd is the ballast bypass circuit, IGN2, usually brown. This only goes one place---from the key switch, out through the bulkhead connector, and to the coil + side of the ballast. It is hot whenever "start" is hot, and IS the power that starts the car

IF YOU have modified the wiring, added aftermarket ignition, eliminated the ballast, etc, check that this brown is incorporated into the new power to the ignition.
