Is Your Hummer H3 Stalling or Failing to Start?
If your 2009 Hummer H3 is experiencing frustrating issues like engine stalling, difficulty starting, a persistent check engine light, or erratic engine performance, the culprit is often a failing 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 your engine receives the precise amount of fuel it needs under all driving conditions. When it fails, it can mimic a bad fuel pump, leading to incorrect and costly repairs.
From the Diagnostic Bay
I remember a 2009 Sierra 1500 (which uses this exact same module) that came in on a tow truck. The owner had just spent a fortune replacing the in-tank fuel pump himself, but the truck still wouldn’t start. He was convinced he got a bad pump. We hooked up the scan tool and saw no communication with the FPCM and a specific diagnostic trouble code, P069E. We checked the module, located on the frame rail, and found it was heavily corroded from road salt and moisture. A new, pre-programmed module had the truck running perfectly in under 30 minutes. He could have saved himself a weekend of frustration and the cost of a fuel pump by diagnosing the FPCM first.
Common Symptoms of a Failing FPCM
- ✔ Engine Cranks but Won’t Start: The module isn’t commanding the fuel pump to turn on, so no fuel reaches the engine.
- ✔ Stalling Under Load: The engine may stall when accelerating or climbing a hill because the module can’t increase fuel delivery to meet demand.
- ✔ Rough Idle or Misfiring: Inconsistent fuel pressure can lead to an unstable idle and engine misfires.
- ✔ Reduced Power and Fuel Economy: The engine isn’t receiving the optimal fuel mixture, leading to poor performance and efficiency.
- ✔ Check Engine Light: You may see codes like P069E, P0230, P0606, or U0109, all pointing towards a fault in the fuel pump control circuit.
The Plug-and-Play Solution for Your 2009 Hummer H3 Fuel Pump Control Module
Replacing the FPCM on these GM vehicles isn’t just a matter of swapping the part. A new module from the dealership requires a separate, expensive programming session using their proprietary tools. Our solution eliminates that hassle and cost. We take a genuine GM module and program it with the latest GM software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This ensures perfect communication with your vehicle’s other computers, like the ECM, and restores original performance and reliability.
This module is a direct replacement for your original part and is guaranteed to be compatible with a wide range of GM vehicles. Simply provide us with your VIN after purchase, and we’ll ship a module that’s ready to install right out of the box. No trips to the dealer, no special tools needed for programming. Just mount the new module, plug in the connectors, and get your truck or SUV back on the road.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact, correct software and calibrations for your specific 2009 Hummer H3. This ensures the module works seamlessly with your engine, transmission, and other systems, making the installation truly plug-and-play.
Where is the FPCM located on my Hummer H3?
On the 2009 Hummer H3, the Fuel Pump Control Module is typically mounted to the rear frame crossmember. On many other compatible GM trucks and SUVs, it’s found on the driver-side frame rail, near the spare tire. It’s exposed to the elements, which is a primary cause of its failure due to corrosion.
Is this a difficult part to replace?
For someone with basic mechanical skills, the replacement is straightforward. It typically involves removing a few bolts and disconnecting one or two electrical connectors. Since our module comes pre-programmed, there is no software or computer work required on your end, which is the most difficult part of the job.
How do I know if my fuel pump or the FPCM is bad?
A proper diagnosis is key. A technician can use a scan tool to check for communication with the FPCM and command the fuel pump on. If there’s no communication or the pump doesn’t respond to the command, the FPCM is a likely suspect. Visual inspection for heavy corrosion on the module and its connectors is also a strong indicator.
Will this part fix my P069E check engine light code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded ON) is one of the most common codes indicating a failed FPCM. Replacing a faulty module with our pre-programmed unit is the correct and definitive fix for this code, provided the wiring is intact.
