Is Your Truck Stalling or Refusing to Start?
If you’re experiencing frustrating issues like engine stalling, hesitation during acceleration, or a complete no-start condition in your 2008-2009 GM truck or SUV, a failing Fuel Pump Control Module (FPCM) is the most likely culprit. 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. When it fails, it can leave you stranded. This isn’t just an inconvenience; it’s a critical failure that needs an immediate and reliable solution.
From the Diagnostic Bay
We had a 2008 Yukon XL come in on a tow truck. The customer was frustrated because he had already replaced the in-tank fuel pump twice, but the truck would still randomly stall and die, especially on hot days. After a few minutes, it would restart, only to die again a few miles down the road. A quick scan revealed a P069E code: “Fuel Pump Control Module Commanded OFF.” We didn’t even bother with extensive electrical testing. We’ve seen this hundreds of times. The original FPCM, mounted on the frame rail, had failed from heat and corrosion. We installed one of our VIN-programmed modules, and the customer called a week later to say his Yukon had never run better. He wasted over $800 on unnecessary fuel pumps before finding the real, simple solution.
Symptoms of a Failing Fuel Pump Control Module
A bad FPCM can mimic other fuel system problems, leading to incorrect diagnoses and wasted money on parts you don’t need. Before you consider replacing your fuel pump, check if your vehicle is exhibiting any of these classic FPCM failure symptoms:
- ✔ Engine cranks but will not start
- ✔ Sudden engine stalling, often without warning
- ✔ Hesitation or sputtering when you accelerate
- ✔ Noticeable loss of engine power or entering ‘limp mode’
- ✔ An active Check Engine Light with fuel system codes like P069E, P0230, P025A, or U0109
- ✔ A buzzing noise from the fuel pump that is inconsistent
The Importance of a Programmed Sierra Denali Fuel Pump Module
Unlike many other electronic modules, you cannot simply buy a new FPCM off the shelf and install it. These modules are vehicle-specific and require programming to your truck’s unique Vehicle Identification Number (VIN). Without proper programming, the module cannot communicate with the vehicle’s Engine Control Module (ECM), and your fuel system will not operate correctly—or at all. Our service completely eliminates this problem. We take your VIN, flash the module with the latest, most stable software directly from GM, and ship you a part that is 100% plug-and-play. This saves you a costly trip to the dealership and the expense of their programming fees.
Plug-and-Play Installation
This module is a direct replacement for the original, designed for a straightforward installation. On most compatible GM trucks and SUVs, the FPCM is located on the driver’s side frame rail, often near the spare tire. The process is as simple as disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it from the frame, and installing the new one in its place. Once installed, reconnect the battery, and you’re ready to go. No programming, no special tools, no hassle.
Guaranteed Compatibility
This module is a direct replacement for a wide range of GM part numbers, ensuring a perfect fit and function. It is compatible with the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. It fits a vast array of vehicles including the Sierra Denali, Silverado, Tahoe, Suburban, Escalade, Yukon, and many more. Please see the full fitment list to confirm it’s the right part for your vehicle.
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not. The main benefit of our product is that we handle all the programming for you before we ship it. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive at your door ready for a plug-and-play installation.
Where is the FPCM located on my 2008 Sierra?
On most 2007-2009 GM trucks and full-size SUVs, the Fuel Pump Control Module is mounted to the driver’s side frame rail, typically above or near the spare tire. It’s exposed to the elements, which is a common reason for its failure.
Will this fix a P069E trouble code?
Yes. The diagnostic trouble code P069E is one of the most common indicators of a failed FPCM. Replacing the faulty module with our pre-programmed unit is the definitive repair for this code in the vast majority of cases.
What is the difference between an FPCM and an FSCM?
There is no difference. They are two different acronyms for the exact same part. FPCM stands for Fuel Pump Control Module, and FSCM stands for Fuel System Control Module. The terms are used interchangeably.
What happens if I forget to provide my VIN?
We cannot ship the module until we have your VIN, as the programming is essential for the part to function. Our customer service team will contact you via email or phone to retrieve the VIN to avoid any delays with your order.
