How Do I Know If My Fuel Pump Has Gone Bad?

The fuel pump is often overlooked in your car. It plays the vital role of transferring gas from the gas tank to your engine so that your car, truck, or SUV can start and run. These parts are meant to last you about 100K miles or more. If it doesn't or if you've surpassed that mileage mark, you may experience some major warning symptoms. 

Sputtering Engine

A sputtering engine is never a good sign. The sputtering symbolizes your engine's starvation of fuel, meaning that your fuel pump is not supplying it with enough power. This symptom can also mean that you have bad spark plugs, so be sure to see a professional for a proper diagnosis.

Low Fuel Pressure

Our technicians at Haglin Automotive can test your fuel pressure to see if see whether your fuel pump is on its way out. You can also try it yourself by buying a fuel pressure gauge at any auto parts store.

Power Loss

If your fuel pump is aging, you'll notice a reduction in engine power. You'll especially experience this when driving on a steep hill. This is an obvious sign that the fuel pump is not delivering enough fuel to the engine. When this happens, your vehicle will not be able to handle particular terrain.

Reduced Gas Mileage

If the fuel pump moves too much or too little gasoline to the engine, you'll notice a drop in gas mileage. As a responsible vehicle owner, you should regularly track your mileage to ensure you're getting the proper fuel efficiency. A drop in fuel efficiency could be connected to a failing fuel pump.

Dead Engine

You may end up with a lifeless engine even if you don't experience any of the mentioned warning symptoms. When the fuel pump gets clogged, it can worsen to the point of not being able to transfer gas to the engine. If this is the case, you won't be able to start your car, truck, or SUV anymore.
