Is Your GM Truck or SUV Stalling or Failing to Start?
There’s nothing more frustrating than a vehicle that won’t run reliably. If your 2008-2009 Chevrolet Avalanche, Silverado, Tahoe, or another compatible GM vehicle is experiencing sudden stalling, hard starting, hesitation under acceleration, or a persistent Check Engine Light, the culprit is often a faulty Fuel Pump Control Module (FPCM). This small but critical component, also known as a Fuel System Control Module (FSCM), is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded without warning.
The Critical Role of the Fuel Pump Control Module
Unlike older fuel systems that ran the pump at full speed constantly, modern GM vehicles use an FPCM to vary the fuel pump’s speed based on engine demand. This intelligent control provides just the right amount of fuel pressure, improving efficiency, reducing emissions, and extending the life of the fuel pump. However, these modules are often mounted on the frame rail, where they are exposed to harsh conditions—water, salt, mud, and vibrations—leading to corrosion and internal electronic failure over time.
Symptoms of a Failing Avalanche 1500 Fuel Module
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or idling and may be difficult to restart.
- ✔ No-Start Condition: The engine cranks but refuses to start due to a lack of fuel pressure.
- ✔ Hesitation or Stumbling: The vehicle may hesitate or stumble during acceleration as the module fails to command adequate fuel flow.
- ✔ Check Engine Light: Diagnostic Trouble Codes (DTCs) such as P069E, P0230, P025A, or U0109 are common indicators of an FPCM failure.
- ✔ Reduced Engine Power: The vehicle may enter a ‘limp mode’ with a “Reduced Power” message on the dash.
- ✔ Erratic Fuel Gauge Readings: In some cases, a failing module can interfere with fuel level signals.
From the Diagnostic Bay
We had a 2009 Silverado 1500 towed in with a classic complaint: it would run fine for about 20 minutes, then stall and refuse to restart for an hour. The owner had already replaced the fuel pump, thinking that was the obvious fix, but the problem persisted. We hooked up our diagnostic scanner and monitored the fuel pressure command from the FPCM. Sure enough, right before it stalled, the command signal dropped to zero. A visual inspection confirmed our suspicions—the original module on the frame rail was heavily corroded. We installed a new, VIN-programmed FPCM, and the truck ran perfectly. It’s a textbook example of how this module’s failure can mimic a bad fuel pump, making proper diagnosis key.
The Plug-and-Play Solution: VIN-Programmed for Your Vehicle
Replacing the FPCM isn’t just a matter of swapping parts. A new module must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) and loaded with the latest GM factory software to communicate correctly with the Engine Control Module (ECM) and other vehicle systems. This typically requires a trip to the dealership and expensive programming fees.
We eliminate that hassle. When you purchase this Avalanche 1500 Fuel Module, we program it for you before it ships. Simply provide us with your VIN during checkout, and you’ll receive a part that is 100% ready for installation. It’s a direct-fit replacement for part number 13501024 and is also compatible with a wide range of other part numbers, including 20759945, 25967325, and more.
Wide-Ranging GM Compatibility
While this is a perfect fit for the 2008-2009 Avalanche, this FPCM is the correct service part for a massive range of GM trucks and SUVs from the era, including:
- Cadillac Escalade, ESV, EXT (2008-2009)
- Chevrolet Silverado & GMC Sierra 1500 (2007-2009)
- Chevrolet Suburban & GMC Yukon XL 1500 (2008-2009)
- Chevrolet Tahoe & GMC Yukon (2008-2009)
- GMC Acadia, Buick Enclave, Saturn Outlook (2009)
- And many more listed in the fitment guide.
Frequently Asked Questions
Why do I need to provide my VIN?
The Fuel Pump Control Module is a computerized component that must be specifically calibrated to your vehicle’s systems. We use your VIN to load the exact GM-specified software and settings for your truck’s engine, transmission, and other options, ensuring seamless communication and proper function right out of the box.
Where is this module located on my vehicle?
On most trucks and large SUVs like the Avalanche, Silverado, and Tahoe, the FPCM is mounted to the driver’s side frame rail, typically above the spare tire. On other vehicles like the GMC Acadia or Chevrolet Traverse, it may be on a rear crossmember. Always consult a service manual for the exact location on your specific model.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, raising the vehicle safely, unplugging the electrical connectors, and unbolting the old module from the frame. Since our module comes pre-programmed, no special tools are needed for software flashing, making the job much simpler.
Will this fix a P069E trouble code?
DTC P069E (Fuel Pump Control Module Commanded On) is one of the most common codes indicating a fault with the FPCM or its circuitry. While this module is the most frequent cause, it’s essential to also check for wiring issues or poor connections to the module before replacement. However, in most cases, replacing the FPCM resolves this code.
What happens if I don’t get a programmed module?
If you install a non-programmed or incorrectly programmed module, your vehicle will likely not start. The module will be unable to communicate with the ECM, and the fuel pump will not activate. Our pre-programming service saves you the time, expense, and hassle of having the vehicle towed to a dealer for this critical step.
