The automotive fuel pump module is built up of a motor, a equipment pump, a pressure damper, along with a discharge valve to circumvent overpressure injury.

This means a dilemma by having an motor sensor or Together with the powertrain Manage module (PCM). It's not necessarily a fuel pump failure, but it is typically misdiagnosed as a Fuel Pump bad fuel pump.

If fuel method pressure is reduced only under load, that doesn’t automatically necessarily mean there’s a little something Completely wrong Using the fuel pump.
