The fuel pump is struggling to supply a consistent stream of fuel to the engine.The condition of the fuel pump is declining, negatively impacting its ability to supply fuel at the proper pressure.The condition of the fuel pump motor is creating resistance in standard functions.The fuel pump’s relief valve is failing to close, supplying more fuel than necessary, and reducing the vehicle’s overall fuel efficiency.
These conditions, and the resulting symptoms listed above, will ultimately result in your vehicle failing to operate or repeatedly stalling.
Inconsistent Fuel Supply to Engine
When the engine is not receiving enough fuel from the fuel pump system, or it is receiving fuel at the incorrect pressure, it cannot maintain engine combustion. This ultimately leads to engine failure: stalling or not starting at all. This can be a sign of damage to the fuel pump, aging of fuel pump, or even clogging of the mechanism. If you are not alerted to the problem by the listed symptoms first, your check engine light will power on and may be indicative of the described conditions.
Deteriorating Condition of Fuel Pump
The age of your fuel pump can ultimately manifest in any of the symptoms listed here, but one of the telltale signs of this is similar to sputtering in acceleration. However, instead of hesitation, the vehicle will surge suddenly, as if the gas pedal were pressed. This happens because, as the fuel pump system ages, different parts may be in better condition than others perform at different rates. While some parts are functioning properly and others are not, inconsistent engine pressures can result in sudden surges in speed while driving.
