Fuel is one of the mysterious ingredients in combustion. Considered as the primary raw material in producing the power that will run your Pontiac, fuel has been among the greatest demands of automobiles. During the power production, it is burned along with the oxygen inside the engine cylinders. The burned fuel is then turned into the horsepower and torque that is consumed by your Pontiac throughout the entire operation.

The air and the fuel are each handled by two separate systems. The air intake system regulates the flow of air from the environment to the engine, while the fuel system handles the gasoline that will be burnt. Before the fuel is consumed, it is initially stored in the fuel tank. The tank is positioned opposite the engine at the other end of your vehicle. When the combustion process starts, the fuel already held in the engine will apparently be consumed. In order to keep the powerhouse in producing power, the fuel stored in the tank must travel to the engine cylinders constantly for continuous operation. And it is the Pontiac fuel pump of your unit that's responsible for that particular task.

The fuel pump is typically categorized into two — the mechanical pump and the electric pump. The former was employed among older vehicles with carburetors, while the latter is being used today by most modern vehicles with an electronic fuel injection system. The fuel injector is the component that directly sprays fuel into the engine cylinders, but its efficiency greatly depends on the amount of fuel that is supplied to it by the pump. The electric fuel pump is located inside the fuel tank and is battery-operated. By generating positive pressure, it pushes the gasoline from the tank into the engine, ensuring that a sufficient amount of fuel is always available for the fuel injector once it opens.

The pump must supply fuel to the injector in correct volume and pressure. Otherwise, the engine will not be able to produce enough power and your Pontiac won't run properly. This is the usual result when the fuel pump malfunctions or fails. This happens when any damage is messing with ant of its components — the brushes, commutator, or armature bushings. If this is the case, the fuel will just sit in your tank and won't reach the injector. It will be as if you are out of gas, even when the tank is full.

You can easily have your Pontiac fuel pump checked and repaired. But if it's too late, then it is best to get a replacement. Parts Train offers fuel pump for different makes and models of vehicles. We have a wide selection of auto parts where you can easily pick the product that you need.
