Fuel issue caused by electrical?

No prime, runs, dies
I bought the vehicle running, terribly, but it was missing the front motor mount, and the passenger's side mount was trashed. I replaced those, drove across the street, put in some fuel, drove back and turned it off while I cleaned up the work space, when I went back out, it began the previously mentioned symptom. Now the only lead I have on finding the issue is at the coil. When I leave the key to the on position, and remove either wire from terminal 15 and try to put it back on the fuel pump will prime just as I begin to put the wire back on or just as I get it off. (Discovered this by accidentally leaving the key to the on position) But not when the connector is completely on.
Parts I have replaced AFTER the symptom started:
Both fuel pumps, and filter
Fusebox (had some melting and needed to be done anyway)
All relays at the fusebox
Coil ground strap
Coil
Ignition Control Module/Unit
Wire connections at the coil for terminal 15
Cleaned connections on the coil itself
Where do I go from here?

Have you replaced the fuel pump relay? You can short out the fuel pump relay to get the pump to run all the time, either remove the fuel pump relay and get a bit of wire between the 2 bigger connections or take out the indicator relay and put that where the fuel pump relay should be, this will make the pump run so you can see if that's the problem.

I suspect this is the same reason some kjet cars prime and some do not.
if the car will run with the relay socket bridged this suggests to me the relay is the problem, open it up and look for burnt contacts or loose/dry/cracked solder joints
