What is a Fuel Pump?

The fuel pump is a subsystem of the engine that pumps gasoline or diesel fuel to the engine. Fuel pumps can fail for many reasons, including dirt and debris clogging the pump or failing magnets. When a fuel pump fails, it will not deliver fuel to the engine and the car will eventually stop running. In order to fix a failing fuel pump, you will need to first identify the problem and then reset the pump.

How a Fuel Pump Works

A fuel pump is a mechanical device that uses energy from a battery or an external power supply to turn an electric motor in order to move fuel from the tank to the engine. Fuel pumps are often malfunctioning, and may need to be replaced. This guide will show you how to reset a fuel pump.

Common Problems with Fuel Pumps

Fuel pumps can malfunction for a variety of reasons, and sometimes it’s difficult to determine the cause. In this article, we’ll discuss some common problems with fuel pumps and how to troubleshoot them.

If your car won’t start, check the fuel pump first. A weak or dead fuel pump can cause your car to not start. To test the fuel pump, unscrew the cap on the fuel filler neck and spray a few drops of gas into the cylinder. If you hear a clicking sound from the pump, it’s probably good and should be replaced. If there is no clicking sound, then it may need to be replaced.

If you have a “check engine” light on your dashboard, your car most likely needs a new oxygen sensor. The oxygen sensor measures air quality in the exhaust and sends data to the computer that controls emission control systems (like catalytic converters). Over time, these sensors can deteriorate and cause poor performance or even an “check engine” light. You can find replacement oxygen sensors online or at any auto parts store.

A clogged or dirty air filter will also cause an “check engine” light. Change your air filter every 3-6 months if you drive in dusty environments or use high-performance gasoline.( source )

How to Reset a Fuel Pump

If your car has a fuel pump, it may need to be reset if it does not start. The procedure for resetting a fuel pump varies depending on the make and model of the car, but typically involves removing the fuel tank and disconnecting the lines going to the pump. After that, you may have to prime (fills up) the pump with gasoline before reattaching the lines.
