If this sound is not audible, it is an indication that the pump relay may not be functioning as it should. As the vehicle’s ignition is turned on, the pump relay produces a humming noise. When the vehicle’s ignition is initiated, a magnetic coil with an open contact is activated the contact then closes an electric circuit in an electronic mechanism and the fuel pump relay is ultimately activated. Until oil pressure is created and in turn generates electricity to run the fuel pump, the pump cannot provide fuel to the car’s engine. This electricity is created by an oil pressure device in the engine. The pump that delivers fuel to the engine while the engine is running requires electricity in order to operate. Without this relay, the engine would not receive fuel while starting. The location can be different, however, in some other cars. The fuel pump relay is usually located in the vehicle’s long black box with the other relays and fuses. The fuel pump relay helps your vehicle start the car by pressurizing the fuel system for the first few seconds before the oil pressure’s level takes over.
