Restore Your Truck’s Performance with a VIN-Programmed Fuel Pump Control Module
Is your 2008-2009 GMC Sierra Denali, or another compatible GM truck/SUV, experiencing frustrating issues like stalling, hesitation, a no-start condition, or a persistent Check Engine Light? Before you condemn the in-tank fuel pump—a costly and labor-intensive job—it’s crucial to inspect the Fuel Pump Control Module (FPCM). This module, also known as a Fuel System Control Module (FSCM), is the brain behind your vehicle’s fuel delivery system, and it’s a known failure point on these platforms.
This genuine GM module, part number 25785013, is the definitive solution to these common problems. Unlike a generic part from a local auto parts store, this module isn’t just a piece of hardware. We provide a complete, ready-to-install solution. Upon purchase, you simply provide us with your vehicle’s VIN. Our certified technicians will then program the module with the latest, most stable software updates directly from General Motors. This ensures perfect communication with your vehicle’s powertrain control module (PCM) and optimal fuel system performance from the moment you install it. No expensive trips to the dealership for programming are required.
From the Diagnostic Bay
We had a 2009 Tahoe come in on a tow truck. The owner had already replaced the in-tank fuel pump himself, a job that took him all weekend, only to have the exact same no-start problem. He was convinced he got a bad pump. We hooked up our diagnostic scanner and saw diagnostic trouble code P069E – ‘Fuel Pump Control Module Commanded OFF’. The FPCM wasn’t sending power to his brand new pump. These modules are mounted on the frame rail, exposed to water, salt, and road debris, which causes corrosion and internal failure. We installed one of our pre-programmed modules, and the truck fired right up. He could have saved himself a weekend of work and hundreds of dollars by diagnosing the FPCM first.
Common Symptoms of a Failing FPCM
A failing Sierra Denali Fuel Pump Module can manifest in several ways, often mimicking a bad fuel pump. If you’re experiencing any of the following, this module is the likely culprit:
- ✔ Engine cranks but will not start.
- ✔ Stalling while driving, especially under load.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor performance.
- ✔ Check Engine Light with codes like P069E, P0230, P0606, or U0109.
- ✔ Inconsistent fuel pressure readings.
Why a Pre-Programmed Module is Essential
Modern vehicles rely on a network of computers that must communicate flawlessly. The FPCM is a key player in this network. When you install a new, unprogrammed module, it’s like hiring an employee who doesn’t speak the language—it simply won’t work. The module must be coded specifically to your vehicle’s VIN to understand the signals from the PCM and command the fuel pump correctly. Our service eliminates this complex step. We handle the programming so you receive a true plug-and-play part, restoring your vehicle’s function without the need for specialized tools or dealer intervention.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is required so we can program the module with the specific software and calibrations for your truck’s engine, transmission, and emissions equipment. This ensures seamless integration and proper function, just like the original part from the factory.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. The module is typically located on the driver’s side frame rail. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. Since our module comes pre-programmed, no further electronic work is needed after installation.
What happens if I install it without programming?
An unprogrammed Fuel Pump Control Module will not function. Your vehicle will likely not start, and it will set communication-related trouble codes. Our pre-programming service is essential for the part to work correctly.
Is this a genuine GM part?
Yes, this is a genuine GM part, programmed with official GM software. This ensures the highest quality, reliability, and perfect compatibility with your vehicle’s complex electronic systems.
How do I find the FPCM on my vehicle?
On most trucks and SUVs like the Sierra, Silverado, Tahoe, and Escalade, the FPCM is mounted to the driver-side frame rail, often near the spare tire. On other models, its location can vary. Always consult a service manual for your specific vehicle to confirm the location before beginning work.
