FAQ
What is a fuel pump?
A fuel pump is a mechanical or electrical device that pumps gasoline or diesel fuel from the gas tank to the engine. In most vehicles, the fuel pump is located inside the gas tank.
What is a fuel pump relay?
A fuel pump relay is an electrical component that controls the power to the fuel pump. The fuel pump relay is usually located in the engine compartment or in a fuse box.
What is an inertia switch?
An inertia switch is a safety device designed to shut off the fuel pump in the event of a collision. The switch is usually located in the trunk or under the dash in most vehicles.
What is a PCM?
A PCM, or Powertrain Control Module, is a computer that controls various systems in the vehicle, including the fuel system. The PCM is usually located under the hood or in the passenger compartment.
What is a fuel tank selector switch?
A fuel tank selector switch is used in vehicles with dual fuel tanks to select which tank is being used. The switch is usually located on the dashboard or near the fuel tank.
