How to Change a Fuel Pump in a Toyota Corolla
The Toyota Corolla fuel pump is electric, so the fuses and relays should be checked before looking at the fuel pump itself. If the fuel tank is not empty but the engine is still having trouble getting fuel, the fuel pump may need to be cleaned or replaced. The Toyota Corolla comes in a variety of styles and trim levels, and this may determine the type of replacement fuel pump.
