The automotive fuel pump is an integral component of a vehicle. Fuel, which is what makes the vehicle run, needs to be pumped from the fuel tank to the engine and delivered under low pressure to the carburetor or under a high pressure to the fuel injection system. Some of the fuel injected engines have two for the purpose which is one of the two pumps is the low pressure/high volume supply pump in the tank and the other one is a high pressure/low volume pump on or near the engine. The fuel pump in your vehicle may be an electric pump or a mechanical pump. In the earlier versions of vehicles, the mechanical pump is being used. It is being driven by a lobe on the camshaft of the engine and is connected to the engine or to the frame rail between the engine and the tank. The modern vehicles being manufactured nowadays are equipped with electric pumps which are positioned on the inside of the fuel tank and are being run by the battery of the vehicle. The primary function of the fuel pump is to push the fuel to the engine by generating a positive pressure on the fuel lines.
In general, the fuel pump is on when the vehicle is switched on. But this does not mean that the ignition switch is the one responsible for carrying the power to the fuel pump. But instead, it activates a relay which will take care of the higher current load that is needed to make the fuel pump work. However, like all the other vehicle components, the fuel pump of your vehicle will eventually fail. If this happens, the entire operation of your vehicle will be extremely affected. At worst, it can cause a chain of damages of the components in the vehicle.
