Recent reports also show that the newer versions of electronic fuel injection (EFI) systems in vehicles are more prone to issues of the Fuel Pump than the previous models. In such a system, the engine becomes quite dependent on precise delivery and regulation of pressure of fuel. When the Fuel Pump fails, the engine stutters and may stall since the fuel injection system can no longer support the correct air-fuel mixture, particularly when extra fuel is required for acceleration.
For example, in a 2018 study by the Automotive Maintenance and Repair Association (AMRA), nearly 15% of all stalling incidents in vehicles equipped with EFI were traced back to faulty Fuel Pumps. This percentage is notably higher compared to older carbureted systems, which have different mechanisms for fuel delivery. The study emphasizes that faulty Fuel Pumps are one of the most common causes of unexpected stalls during acceleration, particularly in vehicles with higher fuel demands.
It is, therefore, important that when a car starts stalling during acceleration, the condition of the Fuel Pump be considered as part of the diagnosis. This way, early detection and replacement of a failing Fuel Pump will help avoid further engine damage and allow the proper restoration of vehicle performance.
Can a Bad Fuel Pump Cause a Car to Stall During Acceleration?
A bad Fuel Pump can definitely cause a car to stall upon acceleration. The main function of the Fuel Pump is to transfer fuel from the tank to the engine with the correct pressure. If it starts malfunctioning, then it would result in erratic fuel flow or even complete starvation of fuel to the engine, especially under high demand situations like acceleration. This may cause it to stall since the engine will lose the power it needs to keep up the speed.
According to the National Highway Traffic Safety Administration, about 2% of all vehicle stalls are directly related to fuel system issues, including problems with the Fuel Pump. A bad fuel pump could result in inadequate fuel pressure, which may lead to loss of power, causing the engine to stall during acceleration. Drivers mostly describe stalling during hard acceleration and driving uphill, both of which are conditions that demand more delivery of fuel for the proper running of the engine.
Data from large automotive repair facilities also indicate that the typical Fuel Pump failure occurs at about 100,000 miles, although this can be earlier or later depending on several variables that include but are not limited to the age of the car, history of maintenance, and quality of fuel. For example, in high-performance cars, it would mean a worn-out fuel pump much faster due to high demands for fuel at fast acceleration.
