Can you drive with a bad fuel pump?
No, you should not drive with a bad fuel pump. A malfunctioning fuel pump can cause significant issues with your vehicle's performance and may even lead to engine failure if left unaddressed. In this article, we'll explore the importance of the fuel pump, the symptoms of a bad fuel pump, and why it's crucial to address the problem promptly.
The Role of the Fuel Pump
The fuel pump is a critical component in your vehicle's fuel system. Its primary function is to draw fuel from the gas tank and deliver it to the engine at the appropriate pressure and flow rate. Without a properly functioning fuel pump, the engine would not receive the necessary fuel, leading to various performance problems and potentially causing the engine to stall or shut off completely.
Symptoms of a Bad Fuel Pump
There are several common signs that your fuel pump may be failing or malfunctioning:
- Difficulty starting the engine: If the fuel pump is not providing enough fuel to the engine, it can make it difficult to start the vehicle, especially when the engine is cold.
- Reduced engine power or acceleration: A bad fuel pump may not be able to deliver the required amount of fuel, resulting in a noticeable decrease in engine power and acceleration.
- Sputtering or stalling: If the fuel pump is not providing a consistent flow of fuel, the engine may sputter or stall, especially at higher speeds or under heavy load.
- Fuel gauge inaccuracy: In some cases, a failing fuel pump can cause the fuel gauge to provide inaccurate readings, making it difficult to determine the actual fuel level in the tank.
If you experience any of these symptoms, it's essential to have your vehicle inspected by a qualified mechanic to determine the root cause and address the issue promptly.
Why You Shouldn't Drive with a Bad Fuel Pump
Driving with a bad fuel pump can lead to several serious problems:
- Engine damage: If the fuel pump is not providing enough fuel, the engine may not receive the proper lubrication, leading to increased friction and potential engine damage.
- Stalling and breakdowns: A malfunctioning fuel pump can cause the engine to stall or shut off unexpectedly, which can be dangerous, especially if it happens while you're driving.
- Decreased fuel efficiency: A bad fuel pump may not be able to deliver the correct amount of fuel, leading to decreased fuel efficiency and higher fuel consumption.
- Safety concerns: Driving with a malfunctioning fuel pump can be a safety hazard, as the vehicle may not respond as expected, increasing the risk of accidents.
If you suspect your fuel pump is failing, it's crucial to have it inspected and repaired as soon as possible to avoid further damage to your vehicle and ensure your safety on 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.
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 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.
How much does it cost to replace a fuel pump?
$1,000 to $1,300
The typical fuel pump replacement cost is $1,000 to $1,300, depending on the vehicle, age, and region. Labor costs range from about $600 to $700, and parts for fuel pump replacement are about $500 to $600. Estimates do not include taxes and fees.
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.

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.
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.
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.
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.
