Like the engine and radiator, fuel pumps are a critical part of your vehicle. Unfortunately, fuel pumps can fail, and knowing what to look for will help you locate the trouble and stop future problems. Below are the four most common reasons fuel pumps stop functioning.

How to Know Your Fuel Pump Is Failing

1. Strange Noises

When your truck starts squealing and making strange sounds, your fuel pump may be suffering. While the issue can stem from a faulty component in the fuel injector housing, low fuel levels, and even subpar fuel quality can damage the part and lead to failure.

2. Engine Problems

Without adequate fuel, your engine may stop completely because it cannot continue to run without the right amount of gasoline. This can lead to a host of engine trouble for your truck down the line. Low-quality fuel may also cause clogs, which will inhibit gasoline from reaching the engine.

3. No Power or Acceleration

If you feel like your vehicle has trouble speeding up, the fuel pump is not sending enough fuel to the engine. You may also notice that the rig seems to lose power as you’re driving. You may spot trouble at startup. Low pressure from the fuel pump will interfere with how easily the engine turns over when you turn the key.

4. Filter Trouble

Frequent filter changes may point to an issue with the fuel pump. For diesel fuel pumps, in particular, problems with the filter are a clear sign that the fuel pump is beginning to fail. If gunk and grime are continually building up, your fuel source may not be clean or of good quality, which will cause a blockage in your fuel pump system.
