Signs My Car Needs a New Fuel Pump

In terms of mileage, the factory fuel pump will last approximately 100,000 miles. In terms of years, it should last about 10 years. After this time, you may start to have one or more of the problems listed below. These problems are signs that the fuel pump is dying and needs to be replaced.

Poor or Surging Engine Performance

There is no way the engine is going to perform efficiently if the fuel pump is malfunctioning. The pump may be unable to send enough fuel to the engine for it to sustain power, especially when it is under stress. A malfunctioning pump can also send too much fuel into the engine. When this happens, the engine will surge unexpectedly in spurts.

Reduction in the Fuel Efficiency

Unfortunately, because the engine is running inefficiently, you will see a reduction in the fuel economy that your vehicle gives you. With gas prices at an all-time high, this can affect your budget if you need to fill up more often. The only way to restore your fuel economy is to replace the fuel pump to restore the engine’s efficiency.

Reduction in the Fuel Pressure

The fuel pressure will also be reduced by a faulty fuel pump. We can test your fuel pressure to see if it is within the normal range for your automobile. If it is lower than normal, this is a sign that the pump is no longer able to produce enough fuel pressure.

Whining Noises in the Fuel Tank

The fuel pump can also give you audible indications that it is going bad. For example, you may hear whining noises in your fuel tank. You may also hear squealing noises. These sounds are made by a fuel pump that is malfunctioning and needs to be replaced.

An Engine That Runs Too Hot

It is strange, but a faulty fuel pump can actually cause your engine to run too hot. The reason why is that the fuel pump motor will get too hot and pass the extra heat on to the engine. Consequently, your engine may overheat even if your cooling system is fine.

Inability to Start Your Automobile

Finally, it makes perfect sense that you will not be able to start your vehicle if the fuel pump has died. You won’t have any fuel in the engine, specifically, the combustion chamber, in order for combustion. Without combustion, the engine cannot run.
