Here are some ways to identify a failing fuel pump:

1. Your car’s engine fails to hit highway speeds. If your engine is misfiring, the car will sometimes jerk when traveling on the highway. Your fuel pump will repeatedly stutter in intervals.

2. Your car loses power when you accelerate from a complete stop. When you try to accelerate, the car begins to go but then appears that it is about to die. Then directly after the car appears to restart and you are able to go.

3. You lose power when you are traveling at highway speeds, even more so when you are traveling uphill. This problem generally indicates a failure in your car’s fuel system. If the problem isn’t the fuel filter, it is most likely that the fuel pump is the cause.

4. Your car cranks when you attempt to start it up, but it will not start. The two things that can cause this problem are a broken timing belt or a broken chain. Without a timing belt, your car will crank but it won’t start up.

Keep in mind that a failed fuel pump that needs to be replaced could be very costly. Therefore getting an auto warranty that can cover the costs might be a smart idea.
