Volkswagen has built a long-standing reputation for manufacturing cars that offer reliability and comfort. It is common knowledge that cars require gas to run, hence the reason why we constantly need to fill up our gas tanks. However, if the Volkswagen fuel pump is faulty, you may have a serious issue on your hands.
The fuel pump is a component of the fuel injection system responsible for moving the fuel from the fuel tank to the fuel injectors in the vehicle’s engine based on the demand of the engine. In most modern cars, the fuel pump is an electric motor pump as opposed to the mechanical pump used in older models. As long as the fuel pump is effective, providing the required amount of fuel at the required pressure, your Volkswagen will continue running smoothly.
A malfunctioning fuel pump will be unable to create enough pressure to push the fuel through the VW relay system to the fuel injectors. If the fuel doesn’t get to the engine, there will be no fuel to ignite and power the engine when you turn on the ignition, it may crank, but it is unlikely to start. If the fuel pump fails while you are on the road, you may experience engine stalling and loss of power. This can be dangerous! You may also notice decreased fuel economy, a fuel leak, whining noises from the engine and an illuminated check engine light. It is not recommended to drive with a malfunctioning fuel pump, and it would be in your best interest to get your Volkswagen to an auto repair shop.
If we suspect a failing fuel pump, we check the fuel injection system from the fuel pump to the fuel filter and the fuel injectors to ensure that the pump is delivering the right amount of fuel with sufficient fuel pressure based on the engine’s demands. We will also check the electrical circuit that powers the pump to confirm if the voltage provided is sufficient to enable the pump.
If the malfunction is as a result of an error in the circuit, then it is an electrical problem unrelated to the fuel pump and will be addressed accordingly. However, if the fuel pump or any other component in the fuel injection system is faulty, then it will require a replacement. As long as your engine is running, your fuel pump is also active, so it is necessary to get your fuel system regularly serviced to keep everything in optimum condition. Even a clog in the fuel filter can affect the efficiency of the pump. The fuel pump is bound to deteriorate with mileage, and with deterioration comes reduced performance.
You do not have to wait for your pump to start malfunctioning or completely fail before you get it replaced. The efficiency of your fuel pump may be the difference between being stranded on the road and getting to your destination safely.
