The fuel pump components
is an important part of your car's engine. It pumps fuel to the injectors and ensures that the car runs at its best. However, if a part of the pump is damaged, you can face a range of problems. These problems may include sudden stalling or a loss of power when your car is under a lot of pressure. This guide will help you understand the parts of the fuel pump assembly and provide you with all the information you need to repair a faulty pump or purchase a replacement.
You can also test the functioning of your fuel pump by using a fuel pressure gauge. This device can be purchased at an auto parts store. If the gauge reads lower than normal, it may be corroded. If you're not sure how to check this, you can conduct a voltage drop test.
The fuel pump assembly contains two main parts. The first part is the pump control module. The pump control module sends a diagnostic signal to the PCM that indicates the duty cycle of the fuel pump. The PCM uses this signal to determine if the actual speed of the fuel pump matches the commanded speed. These signals can be displayed on a scan tool. Some scan tools even allow you to issue commands to adjust the speed of your pump.
Another part of your fuel pump assembly is the fuel pressure regulator. Without this part, your car will either run lean or rich. If your regulator breaks or gets stuck, the fuel will not flow through the fuel line correctly, which will make the engine run rich or lean.
