Is Your 2009 Hummer H3 Stalling, Hesitating, or Refusing to Start?
A frustrating no-start condition, intermittent stalling, or a sudden loss of power in your 2009 Hummer H3 can often be traced back to a single, critical component: the Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This module is the brain behind your vehicle’s fuel delivery system, and when it fails, it can leave you stranded. Don’t let a faulty module compromise the rugged reliability of your H3. This is the direct-fit, VIN-programmed solution you need to restore proper engine performance and get back on the road with confidence.
The FPCM is responsible for precisely managing the voltage supplied to the fuel pump. Unlike older systems that run the pump at full speed constantly, modern vehicles like your Hummer use this module to vary the pump’s speed based on engine demand. This improves efficiency and extends the life of the fuel pump. However, due to its mounting location on the vehicle’s frame, the FPCM is exposed to harsh conditions—road salt, water, mud, and vibrations—which can lead to internal corrosion and electronic failure over time.
From the Diagnostic Bay
We had a 2009 H3 towed in that was a real head-scratcher. The owner said it would die randomly while driving and then refuse to start for an hour or two. The check engine light was on with a P0230 code (Fuel Pump Primary Circuit Malfunction). We checked the fuel pump, relay, and wiring, and everything seemed okay. On a hunch, we located the FPCM on the rear frame rail. The housing looked fine, but once we removed it, we saw the back was swollen and the connector pins were green with corrosion. Water had seeped past the seals over the years. We installed a new, VIN-programmed module, cleared the codes, and the Hummer ran perfectly. It’s a textbook example of how this hidden part can cause major, intermittent headaches.
Symptoms of a Failing 2009 Hummer H3 FPCM
If you’re experiencing any of the following issues, a failing Fuel Pump Control Module is a likely culprit. A faulty FPCM can mimic a bad fuel pump, so proper diagnosis is key. Look out for:
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or idling, often without warning.
- ✔ No-Start Condition: The engine cranks but will not start due to a lack of fuel pressure.
- ✔ Hesitation on Acceleration: The vehicle may stumble or hesitate when you press the gas pedal, as the fuel pump isn’t delivering the required fuel volume.
- ✔ Check Engine Light: Diagnostic Trouble Codes (DTCs) such as P069E, P025A, or U0109 are commonly associated with FPCM failure.
- ✔ Reduced Engine Power: Your H3 may go into a ‘limp mode’ with significantly reduced power to protect the engine.
- ✔ Rough Idle: An inconsistent fuel supply can cause the engine to run rough or idle poorly.
The Plug-and-Play Solution: VIN-Programmed for Your H3
Replacing the FPCM isn’t just about swapping parts. This module is a computer that communicates with your vehicle’s main Engine Control Module (ECM). For it to work correctly, it must be programmed with the correct software and calibration files specific to your Hummer’s Vehicle Identification Number (VIN). Our service eliminates the guesswork and the expensive trip to the dealership. When you purchase this module, we will flash it with the latest GM software updates using your VIN. This ensures:
- Perfect Compatibility: The module is programmed to work seamlessly with your H3’s specific systems.
- No Extra Programming Needed: This part arrives ready for installation. Simply mount it, plug it in, and you’re done.
- Latest Software: We load the most current GM updates, which can resolve issues and improve performance over the original software.
This module is a direct replacement for a wide range of GM vehicles and is compatible with the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325.
Extensive Vehicle Fitment
While this listing is focused on the 2009 Hummer H3, this FPCM also fits a broad selection of other GM trucks and SUVs. Please verify your vehicle is on this list:

Frequently Asked Questions
Do I need to provide my VIN?
Yes, providing your Vehicle Identification Number (VIN) is mandatory. We cannot ship the module until we receive your VIN, as we use it to load the specific software and calibration files for your 2009 Hummer H3, ensuring a true plug-and-play installation.
Where is the FPCM located on a 2009 Hummer H3?
On the 2009 Hummer H3, the Fuel Pump Control Module is typically mounted on the vehicle’s frame rail, near the rear of the truck. This location exposes it to the elements, which is a common reason for its failure.
Is this a difficult part to replace?
For someone with moderate mechanical skill, the replacement is straightforward. It typically involves disconnecting the battery, unplugging the electrical connector, and unbolting the old module from the frame. Since our module comes pre-programmed, no special computer equipment is needed for the installation itself.
Will this fix a P069E check engine light code?
The DTC P069E (Fuel Pump Control Module Commanded ON) is a very strong indicator that the FPCM has failed or is failing. While you should always perform a full diagnosis, replacing the FPCM is the most common and effective repair for this specific code.
How is this different from buying a used module?
A used module will be programmed for the vehicle it came from, not yours. This will cause communication errors and likely won’t solve your problem. Our new module is programmed specifically for your VIN with the latest GM software, guaranteeing compatibility and proper function right out of the box.
