Understanding the implications of a failing fuel pump is crucial for both your safety and the longevity of your vehicle.
Understanding the Fuel Pump's Role
The fuel pump is a vital component of your vehicle's fuel system. Its primary function is to transport fuel from the tank to the engine, ensuring that your car runs smoothly. When the fuel pump begins to fail, it can lead to a variety of issues that may affect your driving experience.
Signs of a Bad Fuel Pump
Before discussing whether you can drive with a bad fuel pump, it's essential to recognize the signs of a failing pump:
- Engine sputtering or stalling, especially at high speeds.
- Difficulty starting the engine.
- Loss of power when accelerating.
- Unusual noises coming from the fuel tank.
- Decreased fuel efficiency.
Can You Drive with a Bad Fuel Pump?
While it may be possible to drive a car with a bad fuel pump for a short distance, it is not advisable. Here are a few reasons why:
- Increased Risk of Breakdown: A failing fuel pump can lead to complete engine failure, leaving you stranded.
- Potential Damage: Continuing to drive with a bad fuel pump can cause further damage to the engine and fuel system, leading to more expensive repairs.
- Safety Concerns: A malfunctioning fuel pump can cause your vehicle to stall unexpectedly, posing a serious safety risk, especially in high-traffic areas.
What to Do If You Suspect a Bad Fuel Pump

Another common symptom of a bad fuel pump is a surging engine. This is caused by too much fuel being sent to the engine. When that happens, you'll notice your engine surging—the vehicle will repeatedly pick up speed and then drop speed, even though you haven't touched the gas pedal or the brake.

No, you can't drive it. Because the fuel pump carries fuel from the Fuel tank to the car engine for combustion if the fuel pump is blocked or broken then there will be no fuel supply to the car engine for combustion.
Do fuel pumps fail suddenly?
Your failing fuel pump could die unexpectedly, but it can also produce symptoms prior to its death.
Can you temporarily fix a fuel pump?
A temporary fix for a faulty fuel pump can be done by bypassing the fuel pump relay. To do this, locate the fuel pump relay in the vehicle's relay box and swap it with the same type. This will bypass the fuel pump's electrical circuit and allow the pump to operate.
