Restore Your Hummer’s Power and Reliability
Is your 2008-2009 Hummer H2 suddenly stalling, hesitating during acceleration, or refusing to start? Before you condemn the fuel pump, the real culprit is often the Fuel Pump Control Module (FPCM). This critical component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to your fuel pump, ensuring precise fuel delivery. When it fails, it can leave you stranded with symptoms that are frustratingly intermittent and difficult to diagnose. This module is the definitive solution, arriving at your door fully programmed with the latest GM software for your specific vehicle.
Case Study: A Tricky Diagnosis
I remember a 2008 H2 that came into my shop on a tow truck. The owner had already replaced the fuel pump himself, but the truck would still crank but not start, or sometimes it would start, run for a few minutes, and then die. He was convinced he got a bad pump. After hooking up my scan tool, I saw no communication with the FPCM (DTC U0109) and a low fuel pressure command code (P069E). Instead of a costly pump job, the fix was this exact module. We found the original FPCM on the driver’s side frame rail, corroded from years of exposure to road salt and moisture—a very common failure point. With a new, pre-programmed module installed, the H2 fired right up and ran perfectly. This simple part saved the customer hundreds in unnecessary repairs and diagnostic time.
Common Signs of a Failing FPCM
- âś” Vehicle cranks but will not start.
- âś” Engine stalls unexpectedly, especially under load or when warm.
- âś” Stuttering, hesitation, or surging during acceleration.
- âś” Noticeable loss of engine power and poor fuel economy.
- âś” An active Check Engine Light with codes such as P069E, P0230, or U0109 (Lost Communication With Fuel Pump Control Module).
- âś” A “Service Fuel System” message on the driver information center.
The Advantage of a Pre-Programmed Solution
Replacing an FPCM isn’t just a mechanical swap. A new module from a dealership requires a specialized, expensive scan tool to program it to your vehicle’s Vehicle Identification Number (VIN). Without this step, the vehicle will not start. We eliminate that entire hassle. By providing us with your VIN during checkout, you receive a 2008-2009 Hummer H2 FPCM that is 100% plug-and-play. It’s loaded with the most current GM-released software, often correcting factory flaws and improving fuel system performance. This saves you a trip to the dealer, eliminates programming fees, and gets your truck back on the road faster.
A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- âś” Locate the Module: On most GM trucks and SUVs, including the Hummer H2, the FPCM is mounted to the driver-side frame rail, typically near the spare tire. It’s a small black box with electrical connectors.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle. Then, unbolt the module from the frame.
- âś” Install the New Module: Bolt your new, pre-programmed FPCM into the original location. Ensure it’s securely fastened.
- âś” Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock into place.
- âś” Final Step: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting the engine to allow the system to initialize. Your installation is complete.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for it to function in your vehicle.
Is this part truly plug-and-play?
Yes. Because we program it to your specific VIN before shipping, it requires no additional setup. Simply install it, and your vehicle is ready to go. You will not need to visit a dealership or mechanic for programming.
Where is the FPCM located on my 2008 Hummer H2?
On the 2008-2009 Hummer H2, the Fuel Pump Control Module is typically mounted on the outside of the driver-side frame rail, located above the spare tire area. It’s exposed to the elements, which is a common reason for its failure.
Will this fix a P069E error code?
Yes, the P069E code (Fuel Pump Control Module Requested MIL Illumination) is one of the most common diagnostic trouble codes indicating a faulty FPCM. Replacing the module with our pre-programmed unit is the correct fix for this code.
What if my original part number is different?
This module is a direct replacement for a wide range of GM part numbers, including 13501024, 20759945, and 25866052, among others listed. As long as your vehicle is on the compatibility list, this module will work perfectly.
