Can you drive a car with a bad fuel pump?
The short answer is no, you should not attempt to drive a car with a bad fuel pump. A malfunctioning fuel pump can cause significant issues and potentially leave you stranded on the road. In this article, we'll explore the importance of the fuel pump, the consequences of driving with a bad one, and what you should do if you suspect your fuel pump is failing.
The Role of the Fuel Pump
The fuel pump is a critical component in a 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 vehicle to stall or not start at all.
Symptoms of a Bad Fuel Pump
There are several common signs that may indicate a failing fuel pump, including:
- Difficulty starting the engine, especially when the vehicle is hot
- Sudden loss of power or engine stalling while driving
- Decreased fuel efficiency or reduced engine performance
- Unusual noises coming from the fuel pump or fuel tank
- Difficulty accelerating or maintaining a consistent speed
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 before attempting to drive the car further.
Consequences of Driving with a Bad Fuel Pump
Attempting to drive a car with a malfunctioning fuel pump can lead to several serious consequences, including:
- Engine Damage: Without a properly functioning fuel pump, the engine may not receive the necessary fuel, leading to overheating, misfiring, and potentially severe engine damage over time.
- Stranded Vehicle: A failing fuel pump can cause the engine to stall or the vehicle to lose power while driving, leaving you stranded on the road and potentially in a dangerous situation.
- Safety Concerns: A malfunctioning fuel pump can affect the vehicle's handling and responsiveness, increasing the risk of accidents and compromising your safety and the safety of other drivers on the road.
It's crucial to address any issues with the fuel pump as soon as possible to avoid these potential consequences and ensure the safe operation of your vehicle.
What to Do if You Suspect a Bad Fuel Pump
If you suspect that your vehicle's fuel pump is failing, the best course of action is to have it inspected and repaired by a professional mechanic. Attempting to drive with a bad fuel pump can lead to further damage and potentially leave you stranded, so it's important to address the issue as soon as possible. By taking proactive steps to maintain your vehicle's fuel system, you can help ensure a safe and reliable driving experience.
How does a car act if the fuel pump is going out?
If your engine is sputtering or stalls in the middle of your drive, your fuel pump is likely the issue. The low pressure caused by a faulty fuel pump means that your engine isn't getting the fuel and air mixture it needs to initiate combustion and power the car.
What happens if you drive 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 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.

Do fuel pumps fail suddenly?
Your failing fuel pump could die unexpectedly, but it can also produce symptoms prior to its death.
How does a car act when the fuel pump is going out?
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.

Can you get a car running with a bad fuel pump?
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.
How long can you ride 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.
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.
