Is Your HUMMER Stalling, Hesitating, or Refusing to Start?
There’s nothing more frustrating than an engine that cranks but won’t start, or one that sputters and dies unexpectedly. If your 2008-2009 HUMMER H2, or another compatible GM truck or SUV, is experiencing these issues, a faulty Fuel Pump Control Module (FPCM) is a very common culprit. This vital component, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel delivery system. When it fails, it can leave you stranded without warning. This replacement module, part number 25866052, is the definitive solution to restore your vehicle’s reliability and performance.
The Critical Role of Your 2008-2009 HUMMER H2 Fuel Pump Module
In modern vehicles, the FPCM is responsible for precisely managing the voltage sent to the in-tank fuel pump. Unlike older systems that ran the pump at full speed constantly, this module varies the pump’s speed based on engine demand. This sophisticated control provides better fuel efficiency, reduces heat in the fuel tank, and extends the life of the fuel pump. However, due to its typical mounting location on the frame rail, the FPCM is exposed to harsh conditions—road salt, water, and vibrations—which often lead to internal corrosion and electronic failure. This failure results in incorrect voltage, or no voltage at all, being sent to the fuel pump, starving your engine of the fuel it needs to run.
From the Diagnostic Bay
We had a 2008 Sierra 1500 towed in with a classic ‘crank, no-start’ condition. The owner had already spent hundreds on a new fuel pump, convinced that was the issue, but the truck still wouldn’t fire up. A quick scan showed a U0109 ‘Lost Communication with Fuel Pump Control Module’ code. We located the module on the driver-side frame rail, and it was heavily corroded. After installing one of our pre-programmed FPCMs, the truck started instantly. The customer could have saved significant time, money, and frustration by diagnosing the FPCM first. It’s a textbook example of why this module should be one of the first things you check for fuel delivery problems on these GM platforms.
Symptoms of a Failing Fuel Pump Control Module
- ✔ Engine Cranks but Won’t Start: The most common symptom. The starter turns the engine over, but it never fires up because there’s no fuel pressure.
- ✔ Stalling or Hesitation: The engine may stall while driving or hesitate during acceleration as the module intermittently fails to command the correct fuel pressure.
- ✔ Reduced Engine Power: Your vehicle may feel sluggish and lack its usual power, sometimes triggering a ‘Reduced Engine Power’ message on the dash.
- ✔ Check Engine Light: Diagnostic Trouble Codes (DTCs) like P069E, P0230, or U0109 are strong indicators of an FPCM-related fault.
- ✔ Whining or Noisy Fuel Pump: An FPCM sending erratic voltage can cause the fuel pump to make unusual noises. Conversely, you may hear no priming sound from the pump at all when you turn the key.
The Plug-and-Play Solution: Programmed Specifically for Your VIN
The biggest hurdle when replacing an FPCM is the need for vehicle-specific programming. Traditionally, this meant buying the part, installing it, and then having your vehicle towed to a dealership for an expensive programming session. We eliminate that entire process. When you purchase this module, you provide us with your vehicle’s 17-digit VIN. Our technicians will then program the module with the latest, most stable software directly from GM for your exact vehicle configuration. When it arrives, it’s ready for a straightforward installation. No extra trips, no dealer fees, no hassle.
This is a genuine OEM-quality part, ensuring perfect communication with your vehicle’s other computers, like the ECM and BCM. It directly replaces a wide range of original part numbers, including 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, and 25967325, making it a versatile fix for many GM trucks and SUVs. Get your vehicle back on the road quickly and confidently with a component that’s built to last and programmed to perform.
Frequently Asked Questions
Do I need to have a dealer program this module?
Absolutely not. The primary benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process simple and saves you from a costly trip to the dealership.
Where is the FPCM located on my vehicle?
On most compatible trucks and SUVs like the HUMMER H2, Silverado, Sierra, and Tahoe, the Fuel Pump Control Module is mounted on the driver-side frame rail, typically above the spare tire. It’s exposed to the elements, which is why failures are common. Always disconnect the battery before beginning replacement.
What happens if I forget to provide my VIN?
Programming is essential for this module to function. We cannot ship your order until we receive your VIN. Please provide your 17-digit VIN in the notes at checkout or send it to us in a message after your purchase to avoid any delays.
Is this a new part?
This is a high-quality, tested replacement part that has been verified for full functionality. It is loaded with the newest software available from the manufacturer to ensure optimal performance and longevity, correcting many of the issues found in the original software.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded On) is one of the most common codes indicating a failed FPCM. While you should always confirm your diagnosis, replacing the module is the standard and effective repair for this code.
