How to Tell If Your Fuel Pump Is Bad

As a vital component of your vehicle's fuel system, the fuel pump delivers fuel from the gas tank to the engine. When your fuel pump isn't working correctly, you'll experience various issues, including a car that won't start or stalling during acceleration. 

What Can Damage Your Fuel Pump?

Several factors can damage your fuel pump and cause it to fail prematurely. Here are some of the most common explanations:

Running on an Empty Tank: Your fuel pump relies on the gasoline in your tank to keep it cool and lubricated. Running on an empty tank can cause the pump to overheat and fail.

Using Low-Quality Fuel: Fuel that contains impurities, such as dirt and debris, can damage your fuel pump's internal components.

Driving on Rough Roads: Repeatedly driving on rough or uneven surfaces can cause the fuel pump's filter to become clogged with debris and dirt, leading to a decline in performance.

Faulty Fuel Filters: Fuel filters prevent dirt and debris from entering your engine, but a clogged or dirty filter can cause your fuel pump to work harder and fail prematurely.

How to Tell If Your Fuel Pump Is Bad

If your fuel pump is failing or has failed, you'll notice several signs that indicate a problem. Here are the most common symptoms:

Difficulty Starting: One of the most apparent signs of a failing fuel pump is difficulty starting your engine. When the fuel pump fails, it won't deliver enough fuel to the engine to start the combustion process.

Loss of Power: If you witness that your vehicle is losing power while driving, it could be due to a failing fuel pump. The engine won't receive enough fuel to keep running.

Engine Sputtering: A sputtering engine is a sign that there isn't enough fuel getting to the engine. Sputters could be due to a clogged fuel filter or a failing fuel pump.

Fuel Pressure Drops: A fuel pressure gauge can determine if your fuel pump is working correctly. Your fuel pump may fail if the pressure drops below your vehicle's recommended specifications.
