What is the Fuel Pump?
The fuel pump’s sole function is to take fuel from the fuel tank and deliver it according to the demand of the engine. When the fuel pump is operating effectively, the car runs smoothly.
Facts to Note:
Before changing the pump, first be sure that filters, fuel pickups, fuel pump relays, and electrical connectors are in good working order. A clogged fuel filter, for example, can restrict flow and cause some of the same symptoms.
How to Fix:
Examine fuel pump and fuel pump relay.
Remove and change fuel pump if defective.
Check car for any signs of leakage.
Clear Check Engine light codes.
Perform basic safety inspection.
Test drive car.
Keep at least 1/4 tank of gas in your car at all times. Low fuel essentially makes the pump work harder and will contribute to its failure.
Common signs indicating you may need to change the Fuel Pump:
Car hesitates to start.
Loss of power or “bucking” when accelerating.
Excessive whining sound.
Check Engine light is on.
Importance of this service:
Your engine needs gas to run. The gas, yet, is stored in the gas tank, not in the engine. When the engine needs more fuel, the fuel pump is in charge of pumping the gas from the tank to the engine, where it is used to power the vehicle. As the fuel pump depreciates, it will be less and less efficient at pumping gas to the engine, and your vehicle will have a harder time running. When the fuel pump totally dies, it will be unable to pump gas to your engine, and your car won’t run.
