A fuel pump is a crucial component in every gas-powered vehicle. It is responsible for supplying the engine with the right amount of fuel at a certain pressure. Without a functional fuel pump, the engine won't receive fuel, causing the car to stall. While a fuel pump typically lasts for about 100,000 miles, it can fail without warning due to various reasons such as fuel contaminants, electrical faults, or natural wear and tear. In this article, we will discuss the signs of a failing fuel pump and provide temporary solutions to get your vehicle moving again until you can get it to a mechanic for a thorough check-up and pump replacement.
How to move a car with a bad fuel pump
| Characteristics | Values |
|---|---|
| Signs of a bad fuel pump | Loud whining noise, engine sputtering, power loss while accelerating, worse vehicle performance, surging, stalling, hard start, poor fuel economy |
| Temporary fixes | Starter fluid, tap the fuel tank to dislodge a stuck fuel pump, manual external pressure, attach a fuel pressure gauge |
| Long-term solutions | Get the vehicle towed to a mechanic shop, replace the fuel pump |
| Prevention | Keep the gas tank at least one-fourth full, keep fuel pump maintenance up-to-date by having filters inspected and replaced regularly |

Confirm the fuel pump is faulty by checking the fuel gauge and trying to start the car.
Confirming that your fuel pump is faulty can be done by checking the fuel gauge and attempting to start the car.
Firstly, when you turn the key to the "on" position, listen out for a humming sound near the fuel tank. If you can't hear anything, this may indicate a problem with the fuel pump. A faulty fuel pump may also make a loud whining sound, which could suggest that the pump is losing pressure and the engine is being starved of gasoline.
You can then try to start the engine. If the fuel pump is completely dead, the engine won't run. However, there may be residual fuel and pressure within the fuel system, which could be enough to start the engine briefly. If the pump is dead, the engine will soon die and refuse to restart.
If the engine does start and run for a short time, the problem is likely fuel-related and could indicate a bad pump. You can then check the fuel pressure to confirm this. Use a gauge to check if the pressure is within the recommended range. If it's too low or high, this could suggest a faulty fuel pump.
It's important to note that other issues can mimic a faulty fuel pump, so it's recommended to consult a professional mechanic if you're unsure or if the issue persists.

Apply manual external pressure to the gas tank to temporarily fix the issue
If your car's fuel pump is failing, you can attempt to get your vehicle started by applying manual external pressure to the gas tank. This method manually replicates the pressure needed to start your car by applying an external pressure source.
To do this, hook up an air pump to your gas tank and run it until the tank becomes pressurized. This will maintain the required pressure level for the car's engine to perform.
You can also try to maintain the heat in your car's engine. The main reason your car starts, even with a failed fuel pump, is that once the car gets cool, the fuel pump resets itself without the required pressure and heat. This results in immediate malfunction and disrupts the car's performance. Thus, maintaining a significant amount of heat in your car's engine can reduce frequent malfunctions and stabilize the car's performance.
However, it is important to note that these are temporary fixes, and you must find a long-term solution by taking your car to a mechanic as soon as possible. Continuing to use a bad fuel pump will damage your car's performance and may cause serious issues such as engine combustion or fire.

Cool the engine to allow the fuel lines to even out and the pump to reset
If your car has a bad fuel pump, you should let the engine cool down for about eight hours. This will allow the fuel lines to even out and the pump to reset. During this time, the vehicle's computer system will also have time to reset.
To cool down an engine, you should first pull over to a safe location to prevent further heat buildup. Then, turn off the engine and carefully open the hood to allow heat to escape. You can also check the coolant levels and top off the reservoir with coolant or water if necessary.
If your vehicle continues to overheat, seek professional assistance immediately.

Drive slowly to a mechanic to prevent the engine from overheating
If your car's fuel pump is failing, you may be able to get it started again through the application of external manual pressure. However, it's best to drive it to the mechanic as soon as possible to prevent a serious combustion issue.
Maintain a Safe Engine Temperature
If your fuel pump is bad, your engine is at risk of overheating. To prevent this, maintain a consistent engine temperature by letting the engine cool off for at least eight hours before attempting to start the car. This will allow the fuel pump to reset without the need for pressure. Driving slowly and avoiding unnecessary acceleration will also help to keep the engine temperature stable.
Avoid Unnecessary Detours
When driving a car with a bad fuel pump, it is important to take the most direct route to the mechanic. Detours can increase the risk of the engine overheating or stalling.
Be Prepared for Emergencies
Bring a fire extinguisher with you when driving a car with a bad fuel pump. In the rare event that your engine catches fire, you will be able to put it out quickly.
Seek Professional Help
While you may be able to get your car running temporarily, it is important to seek professional help as soon as possible. A mechanic will be able to diagnose the issue and provide a long-term solution.

Get the fuel pump replaced, which can cost around $1,000 on average
If your car's fuel pump is malfunctioning, it's best to get it replaced as soon as possible. While there are temporary fixes to get your car running, these are risky and can cause further damage to your engine or even start a fire.
The fuel pump is a crucial component of your car, responsible for transferring fuel from the gas tank to the engine. A failing fuel pump can cause severe performance issues, and if left too long, can lead to costly repairs or even a new engine.
The cost of replacing a fuel pump can vary depending on several factors, including the make and model of your vehicle, the age of the vehicle, the number of labor hours needed, and whether you choose an OEM or aftermarket part. On average, you can expect to pay between $220 and $1,062 for a fuel pump replacement, with labor costs ranging from $124 to $260, or $90 per hour. More expensive vehicles with complex designs can cost upwards of $2,500 to replace the fuel pump.
To save money, you may consider replacing the fuel pump yourself. However, this is a dangerous job that should only be attempted by those with experience working on cars. The fuel pump is typically located inside the fuel tank, and special care must be taken to avoid sparks or fire.

Frequently asked questions
There are several indicators that your fuel pump may be failing, including the engine not starting, sputtering at high speeds, or stalling under load. You may also notice a decrease in fuel efficiency or that your vehicle surges when maintaining a steady speed.
It is not recommended to drive with a bad fuel pump as this can cause further damage to the engine and fuel system. If you must move your car a short distance, it is possible to use starting fluid to temporarily bypass the fuel pump and start the engine.
Yes, a fuel pump may work intermittently before failing completely. This can be due to a number of factors, including a faulty fuel pump relay, a bad fuel pump module, or a clogged fuel filter. If your fuel pump is working sometimes, it's important to address the issue as soon as possible to avoid being stranded.
