Generally, you will get 100,000-plus miles out of your vehicle’s factory fuel pump. Once the automobile has reached the coveted 100,000-mile mark, there is a greater chance that the fuel pump will go bad. Viking Automotive is going to list the problems associated with a malfunctioning fuel pump below.
Performance Loss at High Speeds
One noticeable problem is engine performance loss at high speeds. The engine needs additional fuel to sustain faster speeds. If the fuel pump is malfunctioning and unable to provide the engine with the fuel that it needs, the engine will struggle to run and sputter.
Performance Loss When Stressed
The same is true if your engine is under stress. For example, if you drive a truck and want to tow a trailer behind it, the engine will need additional fuel to sustain power because of the added weight. If the engine lags and struggles to run with the added weight, the fuel pump is going bad.
Strange Surges and Speed Increases
The fuel pump can also make the engine increase in speed and surge. When this happens, it’s a sign that the fuel pump is sending unnecessary fuel into the engine when it doesn’t need it. Consequently, the engine burns the excess fuel and picks up speed unexpectedly.
Reduction in Overall Fuel Economy
All of the above can cause problems with your vehicle’s overall gas mileage. Unfortunately, the problem is you will see a reduction in the fuel economy. In order to get the normal miles per gallon, you will need to replace the malfunctioning fuel pump to restore your engine’s efficient performance.
Reduction in Overall Fuel Pressure
Another problem that occurs with a malfunctioning fuel pump is a reduction in your vehicle’s overall fuel pressure. The pressure range is listed in the owner’s manual. If you test the fuel pressure and it is not within the recommended range, the fuel pump is likely going bad.
Difficult Engine Starts/Dead Engine
Finally, you may find it impossible to get your engine started if the fuel pump is unable to deliver fuel to it. Unfortunately, this is an indication that the fuel pump is no longer working. In this case, you will need to have your vehicle towed to our shop so we can replace the fuel pump.
