* Loss of power. A failing fuel pump can also cause the engine to lose power, especially at high speeds.
* Difficulty starting the engine. A failing fuel pump can make it difficult to start the engine, or may cause the engine to start and then immediately stall.
* Fuel pressure gauge reading low. A fuel pressure gauge can be used to measure the fuel pressure in the fuel line. A reading that is lower than the manufacturer's specification can indicate a failing fuel pump.
* Leaking fuel. A failing fuel pump can also cause leaks, which can be a fire hazard.
If you suspect that your fuel pump is going bad, it is important to have it checked out by a qualified mechanic as soon as possible.
