If your car’s fuel pump is not working, you may be wondering how to reprogram it. This guide will teach you how to do just that, so that you can get your car back on the road as quickly as possible. Keep in mind that this procedure is only for vehicles with a computerized fuel pump control module. If yours isn’t computerized, or if you don’t know which module your car has, don’t worry—you can still fix the problem without reprogramming the pump. Just follow these simple steps and you should be good to go.
What is a Fuel Pump Control Module?
Fuel pump control module (FPCM) is a computerized system that regulates fuel flow to the engine. A defective FPCM can cause an intermittent or complete loss of power to the engine, which may require repair. A faulty FPCM may also result in poor fuel economy and decreased performance. In order to diagnose and fix a faulty FPCM, the vehicle must be brought into a dealership or a private mechanic for inspection.
Reprogramming a fuel pump control module is typically necessary if the original code cannot be read from the module or if there are problems with the code reading procedure. Common problems that might necessitate a reprogramming include: an incorrect voltage being applied to the module; dirty or clogged injectors; incorrect idle settings; and low fuel pressure. In some cases, it may be necessary to replace the entire FPCM if it is found to be defective.
How does a Fuel Pump Control Module work?
Fuel pump controllers are responsible for the operation of fuel pumps in modern vehicles. The controller receives inputs from various sensors and uses this information to determine when to send a pulse of power to the pump, controlling the flow of fuel into the engine. In some cases, reprogramming the fuel pump control module (FPCM) may be necessary to solve certain problems with your car’s fuel system.
A fuel pump control module typically contains a microprocessor and memory, which allows it to store diagnostic data and settings for different engines. When there is an issue with the engine or fuel system, the FPCM will try to find a solution by using this data. Sometimes a problem can occur if the FPCM is not properly programmed or if it has been damaged in some way. If this is the case, you may need to reprogram the FPCM in order to fix your car’s issues.
There are many ways to perform this task, but all involve removing the FPCM from your car and programming it using a custom tool or software. Depending on which model car you have, you may need to remove several parts before you can get at the FPCM. Once you have removed it, you will need to connect your car’s diagnostics port (DIP) to an appropriate USB port on your computer and start up your program.
Once your computer is connected, you should see a window that looks like this:

How to reprogram a Fuel Pump Control Module
If your car is having trouble starting or you’re noticing a lack of fuel economy, it might be time to reprogram the fuel pump control module. This guide will show you how to do it on a 2006-2010 sedan with a 6-cylinder engine.
1. Verify that the car is fully charged – If the car isn’t fully charged, the battery could prevent the computer from recognizing any error codes. Plug in the car and turn it on. If no errors are displayed after a few minutes, disconnect the battery and continue with Step 2.
2. Remove the air cleaner box – On most 2006-2010 sedans, this can be found near the front of the engine compartment next to the radiator (shown above). Use a screwdriver to remove 4 screws around the perimeter of the air cleaner box. Once it’s removed, use a flathead screwdriver to pry up on one of two clips holding in one side of the cover (shown below). Then carefully pull off the cover (shown below).
3. Disconnect all electrical connectors – There are three connectors near each side of the fuel pump control module: black/white striped connector at top left (red arrow shown below), light blue/green striped connector at top right, and tan/brown striped connector at bottom left (blue arrow shown below). Note which color corresponds with each connector: black for ground, white for power, and blue for signal. Unplug each connector by
What are the risks of not reprogramming a Fuel Pump Control Module?
There are a few risks associated with not reprogramming a Fuel Pump Control Module. The first is that the vehicle may not start. If the fuel pump does not receive power, it will not be able to dispense fuel and the car will eventually stall. Additionally, if the module is not reprogrammed, a software error may occur which could lead to poor performance and even safety issues. Lastly, if the wrong code is loaded onto the module, it may cause problems with the car’s engine or braking system.
Conclusion
If you’re experiencing issues with your fuel pump control module, it’s important to take action and get it fixed as soon as possible. By following the steps in this article, you can help troubleshoot the issue and get your car back on the road as quickly as possible. If you don’t know how to do any of these things, don’t worry — a certified technician can usually handle this type of repair for you. Just be sure to call ahead so that they know what kind of car you have and which part is broken. Thank you for reading!
