Do I Need a New Fuel Pump? Here’s Everything You Need to Know

 

The fuel pump is one of the most vital parts of any car. It’s responsible for sending fuel from your tank to your engine. Without a working fuel pump, you can expect to remain parked for the foreseeable future.

 

 

Although most manufacturers design their fuel pumps to last 100,000 miles or more, it’s still possible to be forced to replace it. In that case, a neglected fuel pump can be an incredibly costly repair. If you’re having car trouble, check out the information below to learn if you may need a new fuel pump or what you can do to prevent the eventual need to replace it.

 

What Does the Fuel Pump Actually Do?

To best understand what happens when a fuel pump goes bad, we’ll first need to get an in-depth understanding of what a fuel pump actually does. In most modern vehicles, the fuel pump is a small electric pump located in the gas tank.

 

 

When you start up your engine, this pump sucks in surrounding fuel and pumps it via the fuel lines into the fuel injectors, where it finally enters the combustion cylinders. If your fuel pump is on the outs, this process ceases to occur, depriving your engine of fuel and preventing it from propelling your vehicle forward.

 

The Symptoms of a Bad Fuel Pump

As with most car troubles, the first sign of a bad fuel pump is usually a bad sound. It’s normal for a fuel pump to make light humming noises from within your tank as it runs, but as a pump gets older and begins to wear out, the sound will eventually turn into a loud whirring or droning. This is one of the most common signs of a worn out pump.

 

 

A problem with your fuel pump will eventually affect the flow of fuel to the engine, and may even prevent your car from starting. The truth is, however, even a bad pump will likely continue to operate (albeit, at a low-level of efficiency) before it eventually quits altogether.

 

 

Other symptoms of a bad fuel pump include difficulty starting your vehicle, sputtering, stalling that result from fuel starvation, and sudden bursts of power as a result of your engine being fed differing amounts of fuel.

 

 

These problems won’t go away by continuing to drive. In fact, ignoring a fuel pump in need of attention can lead to serious engine issues such as misfiring, weaker acceleration, and a complete drainage of efficiency altogether.
