If you’re driving your car and it suddenly starts to sputter, lose power, or won’t accelerate, one of the first things you should check is your fuel pump.

A malfunctioning fuel pump can cause several issues with your car’s performance, including sudden acceleration loss and trouble starting.

If you notice any of these symptoms of a bad fuel pump, check with a mechanic immediately. Waiting too long could cause other parts of your car’s engine to fail.

What Is a Fuel Pump?

A fuel pump is a component of your car’s engine that pumps liquid fuel from a fuel tank to the internal combustion engine.

You’ll find it inside the vehicle’s engine compartment, and it typically uses an electric motor to power up.

Five Common Bad Fuel Pump Signs

If you notice that your vehicle is missing or stalling more often than usual, it may be time for your mechanic to inspect your fuel system.

There are several symptoms of a bad fuel pump. Some of the most common bad fuel pump signs that we see at our auto repair center include the following:

  1. Vehicle Power Loss
    You may ask yourself, “What are the signs of a bad fuel pump?”

    The first sign is if your vehicle loses power when loaded with cargo or navigating up a hill. This occurs because the engine requires more gas from the fuel pump to compensate for the stress but doesn’t get it due to a malfunctioning fuel pump.

  2. Engine Sputters
    Your fuel tank contains the fuel pump, which pumps gas at high speed out of your fuel tank into your engine.

    A bad fuel pump will cause your car to sputter and threaten to stall if you try to accelerate quickly. If this happens, you need a new gas tank and fuel pump assembly as soon as possible.

  3. Abnormal Fuel Pump Noise
    If you hear a loud, whining sound coming from your gas tank, it could indicate a bad fuel pump.

    The typical noise your pump makes is a low hum, but if it sounds too loud or high-pitched, the pump may have an issue.

  4. Low Fuel Level
    If your fuel level is low and there are no other issues with your car that would cause this problem (like having a bad battery), it could be one of the symptoms of a bad fuel pump.
  5. Dead Engine
    If your car doesn’t start, the battery may be dead, the alternator is terrible, the starter has failed, or your fuel filter needs to be changed. However, if all those things are working correctly and you still can’t get your engine to turn over, it could be a sign that your fuel pump is bad.

Fuel Pump Replacement Costs

If you’re experiencing issues with your fuel pump, you may wonder what costs you should expect. The average cost to replace a fuel pump is between $220 and $1,065, depending on the age of the pump and the vehicle make.

Additionally, labor costs average $125 and $260, while parts cost from $100 to $855.
