Fabricate a fused jumper(20amp). Install fuel pressure gauge. Remove fuel pump relay. Check for power to relay. Looking at your relay identify the switched part of the circuit and corresponding pins. Install fused jumper to complete this circuit. If you hear the fuel pump run and see good fuel pressure, your problem is on the control side of the relay. If you dont get fuel pressure and your pump is not running, your problem is between the relay and pump.
