Is Your HUMMER H2 Stalling, Hesitating, or Refusing to Start?
A sudden loss of power, engine sputtering, or a complete no-start condition in your 2008-2009 HUMMER H2 can be frustrating and leave you stranded. These are classic signs of a fuel delivery problem, and a very common culprit is a faulty Fuel Pump Control Module (FPCM), sometimes called a Fuel System Control Module (FSCM). This critical component is the brain behind your fuel pump, and when it fails, it can starve your engine of the fuel it needs to run properly. This replacement FPCM, part number 20850907, is the definitive solution to restore your vehicle’s performance and reliability.
Expert Pro Tip
When replacing the FPCM, it’s a great practice to inspect the module’s electrical connector and the main chassis ground wire nearby. These modules are often mounted on the frame rail, exposed to the elements. Corrosion on the connector pins or a weak ground connection can cause erratic voltage, leading to premature failure of the new module. A quick clean with a wire brush and a dab of dielectric grease can save you from future headaches.
Common Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start.
- ✔ Stalling, especially under load or when coming to a stop.
- ✔ Rough idle or engine hesitation during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109.
- ✔ A noticeable whine from the fuel pump that is inconsistent.
Why Choose Our Programmed 2008-2009 HUMMER H2 Fuel Pump Module?
Modern vehicles like your H2 rely on precise communication between electronic modules. The FPCM must be calibrated specifically to your vehicle’s Vehicle Identification Number (VIN) to function correctly. Installing a non-programmed module from a junkyard or a generic parts store will often result in a no-start condition or persistent error codes. We eliminate this problem entirely. By providing us with your VIN during checkout, our technicians will professionally program this module with the latest GM-certified software. This ensures it communicates perfectly with your vehicle’s Powertrain Control Module (PCM) and other systems right out of the box. It’s a true plug-and-play solution that saves you a costly trip to the dealership for programming.
Guaranteed Fitment and Compatibility
This module is a direct replacement for a wide range of GM trucks and SUVs, ensuring OEM-level function and fit. It is a direct replacement for the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. While this listing is focused on the 2008-2009 HUMMER H2, this part also fits many other vehicles including the Cadillac Escalade, Chevy Silverado, GMC Sierra, and more. Restore your vehicle’s fuel system to factory specifications and get back on the road with confidence.
Frequently Asked Questions
Why do you need my VIN for this part?
The Fuel Pump Control Module must be programmed with software specific to your vehicle’s options and calibration. We use your Vehicle Identification Number (VIN) to load the exact GM-approved software onto the module before shipping. This makes the installation process simple and ensures the part functions correctly without requiring a trip to the dealer.
Where is this module located on my 2008-2009 HUMMER H2?
On the HUMMER H2, as with most GM trucks of this era, the FPCM is typically mounted on the driver’s side frame rail, often near the spare tire or just ahead of the rear axle. It’s exposed to the elements, which is a primary reason these modules fail due to moisture and corrosion.
Can a bad FPCM cause a no-start condition?
Absolutely. A completely failed FPCM will not send power to the fuel pump, meaning the engine gets no fuel. This results in a classic ‘crank-no-start’ situation, where the engine turns over but never fires up.
Is this the same as the in-tank fuel pump?
No, this is not the fuel pump. This is the electronic control module that regulates the voltage and speed of the in-tank fuel pump. The pump is located inside your fuel tank, while this module is mounted externally on the vehicle’s frame.
Do I need to perform any additional procedures after installation?
Because we pre-program the module to your VIN, no further software or programming steps are typically required. It is a plug-and-play installation. We do recommend clearing any existing diagnostic trouble codes (DTCs) from your vehicle’s computer after the part is installed.
