Thread: No sound from the diesel fuel pump

Purchased a "spare parts" TD5 and want to get running to put it in a shed. The fuel pump has no normal operational sounds like my daily driver.
The fuel pump harness has 5 volts in it. The fuel filter has no water trap attached (wires hanging loose). Engine turns over easily,my computer reads "open voltage" at the fuel pump
What advise, please. (the car`s purpose is as parts only and it has been useful already).
