1979 CJ5 Starts then dies (2)

So... I want to keep this short bc there are MANY similar threads on this subject, but every issue is slightly different. I went to replace the stereo in my CJ, the wiring was a mess from the PO. previous stereo was jumped directly into the fuse panel. stereo install was not successful, and afterwords the jeep would start, but die within a second despite throttle input.

Step 1: read archive internet forms
Step 2: replaced all fuses
Step 3:replaced ignition module with new
Step 4:

Today, I found out keeping the key in the "start" position will keep it running, dies immediately when returning to "run".

I'm thinking I may have shorted something in the ignition at the steering column?? Haven't checked the coil or the distributor, but from what I read, the start vs. run test narrows this down. Any input appreciated for a noob.

Wiring issue or ign switch itself.
'Start' and 'run' are 2 different circuits.
Do this-Run a jumper wire from the POS(+)side of the battery to the POS(+) side of the coil. Start it-Does it keep run'n now(if it does-pull jumper to 'kill' engine)?
Don't run it to long, with a full 12VDC feed'n the coil--

Check the coil positive for volts when the key is in run. Should be 12 V there.

Under the dash on the side of the steering column not far from the ignition switch plug is a white plug on a red wire with white stripe. This is where a factory tach would hook up and is the main ign power line. Maybe you knocked that loose?

Aounds like you have a bad ballast wire or resistor. However it could just be no power down the red with tracer wire in Run.

It is not fused, it is fed from the switch
