What is a Fuel Pump?

Fuel pumps get the fuel in your car where it needs to go, so you can get where you need to go. Well, when I put it like that, it seems pretty important, doesn’t it?

That’s because it is. A fuel pump is a critical part of a car’s fuel system, so unless you have a fully electric car, it’s a pretty important part of your car. And if you have a fully electric car, what are you reading this article for? This doesn’t concern you!

We humans drink through straws all the time (and let’s hope they’re reusable; save the turtles, people). Think of the fuel pump as your car’s straw. When you start your car, the fuel pump moves fuel from the fuel tank, where it’s located, to the fuel system. The fuel then combusts, and it’s this combustion that starts the car and keeps it running.

And that’s it. That’s literally it. It pumps fuel, so that your engine can use it, so that your car can drive. It’s that important, and also that simple. If only everything in life was like that, am I right?

Now, fuel pumps usually have a pretty long lifespan, but occasionally the wear and tear can cause it to die. And then it will need to be replaced. And while replacing a fuel pump is actually a pretty simple task, getting to it can be pretty difficult. Translation: I don’t care how good that do-it-yourself project you did last weekend turned out. Save this one for the pros.

Symptoms of a failing Fuel Pump

Weird sounds

Whining coming from the fuel tank can be an indication that the fuel pump is starting to die. So, here’s a pretty good lesson to remember: Nobody likes whining. You don’t like it when your car does it. And your friends and family don’t like it when you do it. Try to remember that. In general, weird sounds from your car are never a good sign, and you should always listen to them.

Diminished engine performance

There might be a loss of power if the fuel pump is unable to provide sufficient amount of fuel to the engine. Also, if the fuel delivery issue is more erratic, you might experience surging or sputtering. A less noticeable issue can be a decrease in gas mileage. You also may notice your car surging or running rough.

Difficulty starting

Okay, here’s something I hopefully don’t need to tell you: If your car is having a hard time turning on, something might be wrong. Who knew, right? If the fuel pump is no longer able to supply the required amount of fuel to the engine, your car will begin to show signs of struggling to start. It may take a few seconds longer than it usually does, or it might require a few attempts to get the thing to turn on. If you keep ignoring the issue, , you’ll eventually end up with a car that simply won’t start.

Misfiring

Ahh, misfiring. Many different things can cause misfiring, including a fuel pump that called in sick to work. If the engine isn’t getting enough fuel, then it won’t have the correct air to fuel ratio in the combustion chamber. This can lead to inadequate and unsuccessful combustion, which often results in misfiring.
