How To Tell If Your Volkswagen Fuel Pump Is Going Bad in Pineville? The engine always needs the right amount of fuel for running effectively like the human body needs blood. So, to fulfill the fuel requirements of the engine all models of Volkswagen have an advanced fuel pump that is moving fuel from the fuel tank to the engine at constant pressure and run the engine smoothly. Over time, the fuel pump of the fuel system is failed or malfunctioned for several reasons. It will show different symptoms for alerting the drive about the problem. Try to fix it before it affects the functions of other fuel systems. When the fuel pump of the Volkswagen is failed, consult a mechanic to repair or replace it immediately.
What are the functions of a fuel pump? Now the fuel pump is equipped in the vehicle having an internal combustion engine. Thus, Volkswagen either has a mechanical or electronic fuel pump as per its configuration. Moreover, the fuel pump is drawn the required amount of gasoline from the fuel tank and transfer them to the engine at the right pressure. Subsequently, the fuel pump is distributing fuel to the carburetor at low pressure and distributing it to the fuel injectors under high pressure. The following point defines the functions of two fuel pumps in Volkswagen.
Mechanical fuel pump The mechanical fuel pump is functioned by a camshaf which is pulling the right amount of fuel from the fuel tank to the internal combustion engine. It contains a spring that can apply force to enable the fuel to be expelled from the pump.
Electric fuel pump For transferring the fuel to the internal combustion engine, the electric fuel pumps are generating electrical pressure within the fuel lines. Moreover, the ignition switch is activated by rely on and manage the power supply for increasing the pressure.
Causes behind the fuel pump failure All we know is that the fuel pump is delivering the right amount of fuel to the engine. But it can be failed for the following causes:
When the fuel is contaminated by outside foreign objects like debris, moisture, and corrosion, it will clog the fuel pump eventually. Subsequently, electrical failures like loose or rusted connectors and the melted wiring also fail the fuel pump of the vehicle.
Symptoms of a bad fuel pump The mechanical and electrical fuel pump of Volkswagen can be failed for many reasons. If you notice any of the following defined signs in your vehicle, consult with a car service center as soon as possible.
Losing power while driving uphill When you are driving your Volkswagen by carrying heavy loads or climbing a hill, it will put extra strain on the engine and demand more fuel for maintaining the engine performance. If the fuel pump is failed, then it is unable to fulfill the fuel demand of the engine and put more strain on it. Due to the lack of fuel in the engine, you will notice power loss issues in the vehicle.
The engine won't start If the fuel pump is failed, then the fuel is unable to reach the engine. As a result, the engine won't start or turn over due to the lack of fuel even if the spark plug is firing appropriately. Other reasons are also responsible for causing starting problems in the vehicle. By using a fuel pressure gauge you can easily determine the condition of the fuel pump. In this process, you have to check out the pressure in the fuel lines. If it reads zero, then make sure that the pump is completely failed that needs immediate replacement.
Jerks or sputters at high speeds Like the other signs, the failed fuel pump also causes jerking or sputtering problems in the engine when you drive at high speeds. It is generally caused when the fuel flow to the engine is distracted and the engine receives only air instead of the right amount of fuel for the combustion. When you start the engine, the sputtering sound is only caused for a few minutes and stops when the engine gets back to its normal operations. So diagnose the failed fuel pump in the Volkswagen.
Engine surges When the fuel pump is failed, all of its components wear out eventually and pressure fluctuates in the fuel lines. In these cases, the vehicles are accelerating suddenly for a few moments even they are not pressing the gas pedal that is also known as engine surging. So, consult a mechanic for repairing or replacing the fuel pump ASAP.
Lose power when accelerating During acceleration, the engine demands more fuel to reach its designed performance. As a result, the fuel pump is working very hard for fulfilling the fuel demands of the engine and put more strain on it. Moreover, the failed fuel pump in the car will cause power loss problems when you are trying to accelerate from a stop. So, inspect the fuel pump when the engine stalls while accelerating from a stop.
Conclusion Most of the fuel pump problems are arising in your Volkswagen due to some mechanical problems. If you are living near Pineville, then consult a mechanic for diagnosing the fuel pump and repair or replace it as per the severity of damages.
