Restore Your HUMMER’s Performance and Reliability
If your 2008-2009 HUMMER H2 is experiencing frustrating issues like stalling, hesitation during acceleration, an extended crank time, or a complete no-start condition, a failing Fuel Pump Control Module (FPCM) is a very common cause. As a technician with over two decades of experience, I’ve seen these modules cause countless headaches for owners. Located on the frame rail, they are exposed to harsh road conditions, leading to internal corrosion and failure. This isn’t just an inconvenience; it’s a critical component for your engine’s fuel delivery system.
This replacement FPCM, part number 20850907, is the definitive solution. We take the guesswork and extra cost out of the repair by pre-programming the module to your vehicle’s specific VIN before it ships. This means no expensive trip to the dealership for programming. You get a part that is truly plug-and-play, loaded with the latest GM software updates to ensure optimal performance and longevity.
Real-World Repair Story
Real-World Repair Story
A customer brought in his 2008 HUMMER H2 that would randomly stall at stoplights. He had already replaced the fuel pump, but the problem persisted. His scanner showed a U0109 (Lost Communication with FPCM) code. We put it on the lift and inspected the module on the driver-side frame rail. It was heavily corroded. Instead of just swapping it, we tested the command signal versus actual fuel pressure and saw a significant drop-off right before the stall. Installing a new, VIN-programmed FPCM solved the problem instantly. The pre-flashed unit saved him the dealership programming fee and got his H2 running reliably again.

A Straightforward Guide to Installation
Installing your new 2008-2009 HUMMER H2 FPCM is a manageable job for a confident DIYer. The module is typically located on the driver-side frame rail, near the rear wheel.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FPCM mounted to the inside of the driver-side frame rail. It’s a small silver or black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a socket wrench to remove the bolts or nuts securing the module to the frame.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location using the original hardware.
