73 Duster only starts in "run" not start posistion

I have a 73 Plymouth Duster that I have restored. It purred like a kitten until 1 week ago. It will only start when I let up on the key into the run position IF I get it on the right stroke. Sometimes it takes a few hits but it WILL NOT START in the "start position." I replaced the ballast resistor, ECU, Magnetic pickup, and ignition switch (pain in the butt) also redid a lot of connections to the wiring under the dash to the bulkhead connector. running electrical tests I get 9.5-10 volts on run as it should be but like 5 on start at the resistor and coil. Obviously with only 5 volts its not enough spark to start but IDK why or where it search. It's almost as if it goes through the resistor twice? maybe a shorted wire in my engine bay. I'm going to tear it apart tomorrow.

ANY help would be greatly appreciated I am sooo ready to drive it
