【Fuel Pump】The fuel pump is one of the basic components of the fuel injection system of an electronic fuel injection vehicle. It is located inside the fuel tank of the vehicle that transfers liquid from the fuel tank to the carburetor or fuel injector of the internal combustion engine. The fuel pump works when the engine is started and the engine is running. If the engine is stopped and the ignition switch is still ON, the HFM-SFI control module turns off the fuel pump.
【Time to Replace】 Fuel pump failures can be caused by electrical faults, old age (wear) or fuel contaminants (dirt, moisture or bad gas). Fuel pump failures often occur without warning. A damaged fuel pump might make a loud, whining sound. There are eight signs you might need a pump replacement: Difficult Starts, Sputtering Engine, The Actual Stall, Power Loss, Surging Power, Lower Fuel Efficiency, Dead Engine.
