A faulty fuel pump can indeed cause a car to stall. A fuel pump’s primary function is to deliver fuel from the tank to the engine at the correct pressure. If the fuel pump is not working efficiently, it may not supply the engine with the fuel it needs, causing the car to stall. This issue is especially noticeable during acceleration or at higher speeds when the engine requires a continuous and adequate fuel supply.
Engine sputtering is a symptom of a failing fuel pump. As a fuel pump starts to fail, an engine may not get enough power and stall intermittently. It is estimated that fuel pump failure is responsible for around 5% to 10% of total car stalls, especially in older cars. In one recent analysis of car breakdowns, 8% of all reported problems were related to a faulty fuel pump.
A car stall will occur more frequently when the fuel pump has been deteriorating over time. After some time, the motor of the fuel pump may start failing, or the fuel filter may be clogged and reduce the flow of fuel to the engine. Electrical connections that are loose or corroded may disrupt power supply to the pump and cause an unexpected car stall. Furthermore, a faulty fuel pressure regulator will worsen the situation by sending too much or too little fuel to the engine, which may cause an engine stall.
Real-world examples show that manufacturers like Ford have faced problems with defective fuel pumps in certain models. A good example is the 2018 Ford F-150, which had a number of reports about stalling as a result of defective fuel pumps. In this case, the pump would fail to deliver adequate fuel pressure, which resulted in power loss and stalling while driving.
To remedy these issues, manufacturers recommend periodic servicing of the fuel system, including the inspection of the fuel pump for wear and tear. A good Fuel Pump guarantees that the engine would get a continuous flow of fuel, hence preventing stalling or breakdowns. Regular service can help extend the lifespan of a fuel pump and avoid the costly consequences of having to replace a malfunctioning pump.
If you have issues with your car stalling or think that something in the fuel system is failing, you should replace those parts as soon as possible to keep your car in good condition. If looking for a reliable replacement, Fuel Pump solutions are available to offer durability and efficiency.
