The most common fuel pump used on modern vehicles is the electric fuel pump, and most of the time it is located inside of the fuel tank.

Over time the fuel pump can become worn from age and lack of maintenance – such as missed filter replacements, fuel contamination, or running your vehicle low on fuel. So, If you consistently run the vehicle low on fuel, the pump overheats and can fail prematurely.

Some Of The Warning Signs Are:

  • Whining Noise Coming From the Fuel Tank
  • Difficulty Starting Your Engine
  • Engine Sputtering
  • Engine Stalling at High Temperatures
  • Loss of Power Under Load Or Stress
  • Car Engine Surging
  • Low Or Poor Gas Mileage
  • Car Engine Will Not Start

Most of the time a fuel pump can last the life of the car. However, as the vehicle reaches high mileage, it is not uncommon for fuel pumps to require replacement. Another reason fuel pumps fail is regularly keeping less than 1/4 of a tank of fuel in your car.

Drivers who ignore the warning signs above will eventually end up with an engine that refuses to start. When a fuel pump completely malfunctions, fuel cannot reach the engine upon ignition. Finally, To diagnose a fuel pump malfunction, check for a blown fuse and/or low pressure in the fuel line.
