Fuel pump not priming?

I'm having fuel pump issues. I know it's not the pump itself. The car only runs when GND and F/P are jumped in the diagnostics box. So whatever that exactly bypasses is my problem. Does anyone know? Also I'm guessing that whatever makes the pump prime for a few seconds instead of stay on all the time is what's getting bypassed when you jump those wires.

Thanks.

I checked both relays and the resistor. They all click and have good resistance. I'm banging. My head here. Any insight at all??
