Does the fuel pump fuse have power to both sides of it while cranking the engine over?

If the fuse only has power on 1 side its no good.U may have all this work for nothing.

If the fuse is good, there must be power at both sides of it. If you have replaced the fuse, recheck it again. If it is blown again, you have a short somewhere.

If not you would have to trace an open in the circuit from relay to the fuel pump.

Well what had happend was the guy let it run out of gas an burnt the pump up, its got me pullin my hair out. So the best thang would be to trace wires back to the pump from the relay?

If the fuse has blown again, yes. Disconnect the fuel pump connector and test if it blows again or you can use the terminal at fuel pump relay to fuel pump wire to check for continuity to body with fuel pump wire disconnected.
