So, how can you check if a fuel pump is bad or on the verge of going back? If you do suspect that you have symptoms of a bad fuel pump, you can listen to it to see if it is operating. As the fuel pump attempts to feed the engine fuel, your vehicle may make bucking noises but will not spark up. Your vehicle will act as though it is out of gas, even though the fuel tank is full.

The most obvious signs of a bad fuel pump are your vehicle won’t start, or it starts but does not run for very long before eventually stalling out. If you can already spot failing fuel pump symptoms, chances are your vehicle’s engine is not performing to its optimal efficiency as a result. In most modern vehicles the fuel pump is located in the tank itself and is electric. Your vehicle’s fuel tank is located on the far side of the car from the internal combustion engine, so the fuel pump is needed to provide a constant flow of gasoline to the engine. Without it, your vehicle’s internal combustion engine will not be able to receive the fuel that it requires. Your vehicle is dependent on its fuel pump in order to operate.
