What Are the Signs of a Failing Fuel Pump?

Fuel pump failures or relay problems are common problems as cars start to age. Think about all the fuel your fuel pump has to transfer over the lifetime of your vehicle – that is A LOT! Whether you need the relay or pump replaced, the team at Thom’s Four Wheel Drive can assist with all your fuel system repairs.

 

The fuel pump is responsible for sending the gas in the tank through the fuel system and eventually into the engine where it will get burned for energy. You can be on the lookout for the following symptoms of a bad fuel pump:

  • Problems Starting the Car: If your vehicle is struggling to start, a common culprit is a malfunctioning fuel pump. You might notice sputtering as another accompanying sign.
  • Drop in Engine Power: Even if your car can start successfully, pay attention to how your engine runs. If you feel like you’ve lost a significant amount of power or experienced slow acceleration or misfires, you should consider having your fuel system checked out by a professional. 
  • Lower Fuel Efficiency: When the pump isn’t delivering a consistent amount of fuel to the engine, it can force your car to overcompensate and supply too much to the engine at a time. Therefore, you will lower your MPG and require fill-ups more often.
  • Whining Sounds: A failing fuel pump sometimes creates a whining noise to signal trouble. If it sounds like it is coming from the back of your car, please have the pump inspected.

If you notice any of the above signs, please be sure to reach out to the professional team at Thom’s Four Wheel Drive for proper inspections. Our team can perform a thorough inspection of your fuel system to ensure your vehicle runs efficiently and smoothly. Please give us a call or visit if you need your fuel pump or relay repaired today.
