Can you drive with a bad fuel pump?
As the owner of Kevin's Autos, I often encounter questions about vehicle maintenance and safety. One common concern among drivers is whether it's safe to drive with a bad fuel pump. Understanding the role of the fuel pump and the implications of driving with a malfunctioning one is crucial for your vehicle's health and your safety on the road.
Understanding the Fuel Pump
The fuel pump is a vital component of your vehicle's fuel system. Its primary function is to transport fuel from the gas tank to the engine. A properly functioning fuel pump ensures that the engine receives the right amount of fuel at the correct pressure, which is essential for optimal performance.
Signs of a Bad Fuel Pump
Before discussing whether you can drive with a bad fuel pump, it's important to recognize the signs that indicate a problem:
- 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 short distance with a bad fuel pump, it is not advisable. Here are several reasons why:
- Increased Risk of Breakdown: A failing fuel pump can lead to complete engine failure, leaving you stranded.
- Potential Damage to the Engine: Insufficient fuel delivery can cause the engine to run lean, leading to overheating and severe damage.
- Safety Hazards: Stalling in traffic or on the highway can create dangerous situations for you and other drivers.
What to Do If You Suspect a Bad Fuel Pump
If you notice any signs of a failing fuel pump, it's crucial to address the issue promptly. Here are steps you should take:
- Do Not Ignore the Symptoms: Pay attention to any changes in your vehicle's performance.
- Consult a Professional: Bring your vehicle to a trusted auto service center, like Kevin's Autos, for a thorough inspection.

Frequently Asked Questions
Will a car still run with a bad fuel pump?
Driving with a bad fuel pump can be risky and potentially dangerous. If your fuel pump fails while driving, your car will likely stall, leaving you stranded on the road. Additionally, a failing fuel pump can cause your engine to run lean, which can lead to overheating and damage to other engine components.
How long does it take a mechanic to fix a fuel pump?
In most cases, around two to three hours. However, job times can vary widely depending on how easy it is to access the pump. The fuel pump sits inside the fuel tank, and is attached to a plate on the top of the tank. On some vehicles, the body has an access cover directly above this plate.
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.
How long can you drive with a bad fuel pump?
If it's bad but running, you could drive for up to 30 minutes before it fails. You mostly won't be able to start the car when it fails.
What happens if you don't fix a bad fuel pump?
Driving with a broken fuel pump inevitably causes significant driving performance issues. For instance, one of the minor issues it causes is lower gas mileage. Plus, prolonged use of the vehicle with a failing pump may cause damage to the engine itself.
Will a bad fuel pump shut off while driving?
The simple answer is yes. If the fuel pump goes out while driving, it's most likely that the vehicle will stall and break down in the middle of the road.
How does a vehicle act when the fuel pump is going out?
This poor start will take the form of a sputtering, stuttering, stammering sort of start, as if your car's engine is only getting a trickle of fuel instead of the amount it needs. Your car may also stall during operation because the fuel pump is bad.
What happens if the fuel pump dies while driving?
If the fuel pump goes out while driving, it's most likely that the vehicle will stall and break down in the middle of the road. Once that happens, you may not be able to start your car or machinery again.
