No power to fuel pump past relay

Hello! Looking for some help on my Jeep. It’s an ‘84 CJ, but I have the 4.0/ AX-15. It has the complete wiring harness to run the motor and trans along with spliced in parts of the ‘84 harness for dash equipment. I built this years ago and just recently ran into stalking issues. It has an inline EXTERIOR fuel pump. Last summer I had issues with it stalling after long drives. Purifoy it would completely die, but after letting it sit, it would fire up enough to get home. A few weeks ago, I noticed the fuel pump was not priming when the key was in “ON”, and now it won’t start at all. What I’ve done so far-
Ran dedicated wires from the battery and engine relay box for ground and power. The pump runs if I direct wire it to the battery but the motor still won’t start.
Traded out different relays for the pump and ASD. No change.
Checked and I have 12v at the pump relay but no power past it.
So got some reason I have power to the relay, but no priming of the pump, or power to it when I try to start the motor.
Any suggestions ?
