Is Your 2008-2009 Tahoe Stalling, Hesitating, or Refusing to Start?
A sudden loss of power, an engine that cranks but won’t start, or a persistent Check Engine Light can be incredibly frustrating. For many owners of 2008-2009 Chevrolet Tahoes and other GM trucks and SUVs, these symptoms point directly to a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component is responsible for precisely managing the voltage sent to your fuel pump, ensuring your engine receives the exact amount of fuel it needs under all driving conditions. When it fails, it can leave you stranded and scratching your head.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in that was a classic ‘crank-no-start.’ The owner had already replaced the in-tank fuel pump himself, assuming it was the culprit, but the problem persisted. He was frustrated and out a few hundred dollars. We hooked up our scanner and saw no fuel pressure reading. Instead of just condemning the new pump, we checked for power at the FPCM connector. We had power going in, but nothing coming out to the pump. A quick inspection of the module, located on the frame rail, revealed heavy corrosion on the casing and connector. We installed a VIN-programmed FPCM, and the truck fired right up. It’s a textbook example of how diagnosing the control side of the circuit first can save you from replacing a perfectly good fuel pump.
Common Symptoms of a Failing FPCM
If you’re experiencing any of the following issues, a faulty fuel pump control module could be the root cause. Don’t let a small electronic box disrupt your vehicle’s reliability. Look out for these tell-tale signs:
- âś” Engine cranks but fails to start.
- âś” Sudden engine stalling, especially while driving.
- âś” Hesitation or stumbling during acceleration.
- âś” Rough idling or inconsistent engine performance.
- âś” Reduced power and poor fuel economy.
- âś” A Check Engine Light with codes like P069E, P0230, or U0109.
The Plug-and-Play Solution: A Pre-Programmed 2008-2009 Tahoe Fuel Pump Module
Replacing the FPCM on these vehicles isn’t just a matter of swapping parts. A new module from the dealership requires expensive programming with specialized tools to sync it with your vehicle’s Vehicle Identification Number (VIN). This means a costly trip to the dealer and extra labor charges. We eliminate that hassle completely. This module, part number 25854536, is a direct-fit replacement for your original, and we handle the programming for you. Simply provide us with your vehicle’s VIN after purchase, and we will flash the module with the latest GM-certified software specific to your exact vehicle. When it arrives, it’s ready for a straightforward installation, saving you time, money, and a trip to the service center.
Why Choose a VIN-Programmed Module?
The FPCM communicates with the Engine Control Module (ECM) and other vehicle systems. Without the correct programming, it won’t function correctly, leading to the same performance issues you’re trying to fix. Our professional programming service ensures seamless integration and factory-level performance right out of the box. This 2008-2009 Tahoe Fuel Pump Module is guaranteed to work with your vehicle’s specific configuration.
Wide-Ranging GM Compatibility
This FPCM is not just for the Tahoe. It’s a common part across a huge range of popular GM trucks and SUVs from this era. It is a direct replacement for multiple part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not! That’s the primary benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. It arrives at your door ready to be installed, with no additional programming or calibration required.
Where is the FPCM located on my 2008-2009 Tahoe?
On most GM trucks and SUVs of this generation, including the Tahoe, Suburban, and Silverado, the Fuel Pump Control Module is typically mounted to the driver’s side frame rail, often near the spare tire. It’s exposed to the elements, which is a primary reason for its failure due to water intrusion and corrosion.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship the module until we have this information, as the programming is essential for it to function in your vehicle.
Is this part the same as a fuel pump driver module?
Yes, the terms Fuel Pump Control Module (FPCM), Fuel System Control Module (FSCM), and Fuel Pump Driver Module (FPDM) are often used interchangeably to describe the same component. Its job is to control the voltage and operation of the electric fuel pump.
What if my old part number is different from 25854536?
No problem. This module is a compatible replacement for a range of part numbers, including 13501024, 15213110, 20759945, 20850907, 25785013, 25866052, and 25967325. As long as your original part number is on this list, this module will work perfectly as a replacement.
