Is Your 2008-2009 GM Truck or SUV Struggling to Run?
Are you dealing with frustrating and unpredictable engine problems in your 2008-2009 Chevrolet Tahoe, Silverado, or other compatible GM vehicle? Issues like the engine cranking but refusing to start, sudden stalling in traffic, or a persistent Check Engine Light can be more than just an annoyance—they can be a significant safety concern. These symptoms often point to a problem within the fuel delivery system. While many people immediately suspect the fuel pump, a very common and often overlooked culprit is a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM).
This vital component acts as the brain for your fuel pump, regulating the voltage it receives to ensure precise fuel pressure for optimal engine performance and efficiency. When the FPCM begins to fail, it can starve your engine of fuel, leading to a host of performance issues. This listing is for a direct-fit, professionally programmed Fuel Pump Control Module, part number 25967325, designed to permanently solve these problems and restore your vehicle’s reliability.
From the Diagnostic Bay
We had a 2008 GMC Sierra 1500 come into the shop on a tow truck. The owner was frustrated because he had just spent his entire weekend replacing the in-tank fuel pump, but the truck still wouldn’t fire up. He was convinced he’d received a faulty pump. Our first step was to connect a diagnostic scanner, which immediately showed a “No Communication” error with the Fuel Pump Control Module. A quick visual inspection of the module, mounted on the driver’s side frame rail, revealed heavy corrosion on the housing and connector pins. We installed this exact pre-programmed FPCM, and the truck started instantly on the first try. The owner had wasted hundreds of dollars and a full weekend on a part he didn’t need. On these GM platforms, always inspect the FPCM for corrosion and test its function before condemning the in-tank pump.
Common Symptoms of a Failing FPCM
A faulty fuel pump control module can manifest in various ways. If your vehicle is experiencing any of the following, a failing FPCM is a highly likely cause:
- ✔ Engine Cranks but Won’t Start: The starter turns the engine over, but it never catches and runs because no fuel is being delivered.
- ✔ Sudden Stalling: The engine may die unexpectedly while driving or idling, often becoming more frequent as the module heats up.
- ✔ Hesitation and Sputtering: During acceleration, the vehicle may hesitate, sputter, or feel like it’s losing power due to inconsistent fuel delivery.
- ✔ Reduced Engine Power: Your vehicle may enter a “limp mode,” limiting speed and performance to protect the engine.
- ✔ Check Engine Light (CEL): Specific diagnostic trouble codes (DTCs) are strong indicators. Look for codes like P069E, P0230, P025A, U0109, which directly relate to the FPCM or its circuit.
- ✔ Rough Idle: An unstable idle can be caused by fluctuating fuel pressure managed by a faulty module.
The Plug-and-Play Solution: Our Pre-Programmed 2008-2009 Tahoe Fuel Pump Module
The biggest challenge when replacing a modern electronic module is the need for expensive, dealer-specific programming. This module eliminates that step entirely. We take the hassle and expense out of the repair by programming the module for you before it ships. When you purchase, you simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians will then use official GM software to load the latest, most stable calibration specific to your exact vehicle configuration. This ensures perfect compatibility and performance right out of the box.
Benefits of our Pre-Programmed FPCM:
- No Dealer Visit Required: Save hundreds of dollars in programming fees and the inconvenience of a trip to the dealership.
- Latest GM Software: We flash the module with the newest updates from General Motors, which often include fixes for factory bugs and improvements in performance and longevity.
- Simple Installation: Because the programming is done, the physical installation is a straightforward bolt-on, plug-in process for any competent DIY mechanic or professional technician.
- Guaranteed Compatibility: By using your VIN, we ensure the module works seamlessly with your vehicle’s engine, transmission, and other systems.

Frequently Asked Questions
What does a Fuel Pump Control Module (FPCM) do?
The FPCM is a small computer that receives commands from the main Engine Control Module (ECM) and then precisely controls the speed of the electric fuel pump. Instead of the pump running at 100% all the time, the FPCM varies the voltage to adjust pump speed, providing the exact amount of fuel the engine needs. This improves efficiency, reduces noise, and extends the life of the fuel pump.
Is this module truly plug-and-play?
Yes. Because we program the module to your vehicle’s specific VIN before shipping, it will not require any additional programming or setup after installation. Simply disconnect the old module, install the new one, and you’re ready to go. It’s the most straightforward way to complete this repair.
Where is the FPCM located on a 2008-2009 Tahoe?
On most GM trucks and SUVs from this era, including the Tahoe, Yukon, Silverado, and Sierra, the FPCM is typically mounted to the frame. You can usually find it on the driver’s side frame rail, often near or above the spare tire. Its location exposes it to road salt, water, and debris, which is a primary reason these modules fail due to corrosion.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is like a fingerprint for your car. It contains specific information about its engine, transmission, emissions equipment, and other factory options. Using your VIN allows us to download the exact software calibration file from GM for your vehicle, ensuring the module functions perfectly and communicates correctly with all other onboard computers.
Will this fix a P069E trouble code?
The diagnostic trouble code P069E (Fuel Pump Control Module Requested MIL Illumination) is a very strong indicator that the FPCM has detected an internal fault or a critical issue in the fuel system that it monitors. Replacing a faulty FPCM is the most common and effective solution for this specific code.
