Is there any reason why a 6.5 turbo would run with the fuel pump wires being disconnected because my uncles truck is experiencing that
Thanks

That means the fuel system and IP is healthy. The IP has a transfer pump, and it will draw fuel if it's primed. It's additional strain on the pump, so I don't suggest you let it continue now you know about it (fix the LP).
so we replaced the fuel pump relay but it still fails to get power to the pump unless power is jumped at the relay. The pump is supposed to have power at all times after startup right?. Our fuel pump only has power to it while the motor is cranked but once it starts the power shuts off....
At the rear of the vally, behind the glow plug relay is the oil pressure switch. It's a fail safe if the engine quits it shuts off the fuel pump. When they go bad, no power to the pump after cranking.

Thanks for the diagram. That was very helpful. It was the OPS that was giving us trouble. Now she runs like a champ
