Signs of a failing fuel pump
The fuel pump is a crucial component of your car's engine, delivering fuel from the tank to the engine to ensure smooth and efficient operation. While fuel pumps are designed to be long-lasting, they can occasionally fail and need to be replaced. Here are some signs that your fuel pump may be failing:
Engine "Chokes" or Struggles to Maintain Speed
If your engine "chokes" or struggles to maintain speed, it could be a sign that the fuel pump is not delivering enough fuel to the engine. This can cause the engine to sputter or misfire, especially during acceleration.
Engine Stalling
A failing fuel pump may cause your engine to stall unexpectedly while driving. This is often due to the pump not providing a constant stream of fuel at higher speeds, causing the engine to threaten to stall or actually stall.
Decreased Fuel Efficiency
If you notice that you're making more frequent trips to the gas station and your vehicle's fuel efficiency has decreased significantly, it could be a sign that the fuel pump is pushing too much fuel into the engine, causing you to burn through gas faster than normal.
Engine Won't Start
A failing fuel pump may cause difficulty in starting your vehicle, requiring extended cranking before the engine kicks in. In some cases, the engine may not start at all, indicating a potential issue with the fuel pump or other components like the battery, alternator, starter, or fuel filter.
Whirring Noise from the Fuel Tank
Fuel pumps are typically designed to operate quietly. If you hear a whirring noise coming from your fuel tank, it could be a sign that the fuel pump is failing or about to fail.
Check Engine Light Comes On
If the fuel flow becomes restricted due to a failing fuel pump, it can cause the ""check engine" light to illuminate. This warning light indicates that there may be an issue with the engine or emissions system, including a potential problem with the fuel pump.
If you experience any of these symptoms, it is important to have your vehicle diagnosed by a qualified mechanic as soon as possible to determine if the fuel pump or another issue is causing the problem.

Fuel pump malfunctions
The fuel pump is a critical component of a car's fuel system, delivering fuel from the tank to the engine to power the vehicle. Although fuel pumps are designed to last the lifetime of a vehicle, they can occasionally malfunction. Here are some signs that indicate a potential malfunction in the fuel pump of your car:
- Engine struggles to maintain speed or misfires: If the engine of your car is choking or struggling to maintain speed, it could be a sign of a failing fuel pump. This can manifest as frequent engine misfires, especially during acceleration.
- Difficulty in starting the engine: You may experience difficulty in starting the car, requiring extended cranking before the engine starts. In some cases, the car may not start at all, even after multiple attempts.
- Stalling or surging: A malfunctioning fuel pump can cause the engine to stall or surge unexpectedly while driving. This can be due to insufficient fuel delivery to the engine, causing it to shut off.
- Decreased fuel efficiency: A failing fuel pump may lead to a significant drop in fuel efficiency, resulting in more frequent trips to the gas station.
- Engine overheating: If the fuel pump causes the engine to receive too much fuel, it can lead to overheating. This can also result in power surges while driving, causing speed spikes and drops.
- Whining noise from the fuel tank: A damaged fuel pump may emit a loud, whining noise, indicating a potential issue. However, it's important to note that a properly functioning fuel pump should only produce a low hum.
- Loss of power: If your car loses power when driving uphill or carrying cargo, it could be due to a faulty fuel pump. The engine requires more fuel to operate under stress, and a malfunctioning pump may not be able to deliver the required amount.
If you suspect a fuel pump malfunction, it is essential to consult a qualified mechanic for a proper diagnosis and repair. The average cost for a fuel pump replacement in a Jeep Liberty is estimated to be between $1,319 and $1,514, but prices can vary depending on the specific vehicle and labor costs. Additionally, prices for fuel pump modules for the Jeep Liberty range from $46.38 to $77.22.

Fuel pump relay replacement
The fuel pump is located inside the fuel tank of your Jeep Liberty and has a small electric motor to ensure that pressurised gasoline flows to the engine. The fuel passes through a filter inside the fuel tank or externally in the fuel flow line.
A fuel pump relay replacement is necessary when the relay is not working properly and does not activate the fuel pump, causing your car not to start. The fuel pump relay is also called the relay switch and is a black plastic component set in a small box with a wiring harness attached to its underside. Its sprockets are attached to the engine assembly. You can find the fuel pump relay under the hood or under the dashboard, near the steering wheel.
Fuel pump relays can oxidize or rust and need to be changed more frequently than the fuel pump. Typically, the coil and contact points of the fuel pump relay show damage. A malfunctioning fuel pump relay could conduct too much power to the fuel pump and damage or ruin it completely.
The replacement procedure involves disconnecting the battery to reduce the chance of a fire. For pumps inside the fuel tank, there will be an access cover that needs to be removed. With the cover off, the technician can replace the pump and pre-pump filter screen. In some cases, fuel will need to be drained before removing the access panel. When the pump is outside the tank, the mechanic will disconnect the fuel lines, remove the pump, and install the new one.
The average national cost for a fuel pump replacement across all vehicles is roughly between $611 and $894, including parts and labour. The cost of a fuel pump relay replacement for a Jeep Liberty is approximately $15.21 for the part.
