Is Your Truck Stalling, Hesitating, or Refusing to Start?
If your 2007-2009 GM truck or SUV is experiencing erratic engine behavior, the culprit might not be the fuel pump itself, but the sophisticated electronic unit that controls it. The Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is the brain behind your vehicle’s fuel delivery. When it fails, it can cause a host of frustrating and potentially dangerous issues, from poor performance and fuel economy to leaving you stranded on the side of the road. This replacement FPCM, part number 25967325, is the definitive solution to restore your vehicle’s reliability and performance.
The Critical Role of Your Sierra 1500 Fuel Pump Module
Unlike older fuel systems that ran the pump at full power continuously, modern GM vehicles use this module to precisely regulate the voltage sent to the fuel pump. It uses Pulse Width Modulation (PWM) to vary the pump’s speed based on real-time data from the Engine Control Module (ECM). This intelligent control provides just the right amount of fuel pressure for any given condition—be it idling at a stoplight, cruising on the highway, or towing a heavy load. This efficiency reduces wear on the fuel pump, improves fuel economy, and lowers emissions. However, due to its typical mounting location on the vehicle’s frame rail, the FPCM is constantly exposed to moisture, road salt, and vibrations, making it a common point of failure.
From the Diagnostic Bay
We had a 2008 Silverado 1500 come into the shop on a tow truck. The owner was frustrated because he had already replaced the in-tank fuel pump twice in six months, but the truck kept dying intermittently and throwing a P069E trouble code. He was convinced he kept getting faulty pumps. We put it on the lift, and the first thing we checked was the FPCM, located on the frame crossmember above the spare tire. The aluminum housing was heavily corroded, and the connectors were green with oxidation. We plugged in our scan tool and commanded the fuel pump on—nothing. We then bypassed the module and sent power directly to the pump, which whirred to life immediately. The problem was never the pump; it was this module. After installing a new, pre-programmed FPCM, the truck’s fuel pressure was stable, the code was gone, and the customer drove away with a permanently fixed vehicle.
Symptoms of a Failing Fuel Pump Control Module
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or after coming to a stop, often with no warning.
- ✔ No-Start Condition: The engine cranks but will not start due to a complete lack of fuel pressure.
- ✔ Engine Hesitation or Stumbling: The vehicle may hesitate or stumble during acceleration as the module fails to command the necessary fuel pressure.
- ✔ Reduced Power & Poor Performance: You may notice a significant loss of power, especially under load, and decreased fuel efficiency.
- ✔ Check Engine Light: A failing FPCM will often trigger diagnostic trouble codes (DTCs). Common codes include P069E, P0230, P0627, and U0109 (Loss of Communication with FPCM).
- ✔ Rough Idle: The engine may idle erratically due to inconsistent fuel delivery.
The Plug-and-Play Advantage: Pre-Programmed for Your VIN
One of the biggest challenges when replacing modern electronic modules is the need for expensive and time-consuming dealership programming. This Sierra 1500 Fuel Pump Module eliminates that hassle completely. We use your vehicle’s unique Vehicle Identification Number (VIN) to load the latest GM-certified software and calibration files onto the module before it ships. This ensures perfect compatibility and communication with your vehicle’s other systems right out of the box. Simply provide your VIN at checkout, and you’ll receive a true plug-and-play part. No special tools, no trip to the dealer—just a straightforward installation to get you back on the road fast.
This module is a direct replacement for a wide range of GM vehicles and is compatible with numerous original part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. Restore your vehicle’s fuel system to factory-spec operation and drive with confidence.
Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. This is the primary benefit of our service. We program the module to your specific VIN before we ship it. This makes it a true plug-and-play installation, saving you time and the high cost of dealership programming.
Where is the FPCM located on my 2008 Sierra 1500?
On most 2007-2009 GM trucks and full-size SUVs (like the Sierra, Silverado, Tahoe, Yukon, and Escalade), the Fuel Pump Control Module is mounted on the driver’s side frame rail, typically on a crossmember above or near the spare tire. It’s exposed to the elements, which is a primary reason for its high failure rate.
Can a bad FPCM damage my new fuel pump?
While less common, a faulty module sending erratic voltage could potentially shorten the life of a fuel pump. More importantly, a bad FPCM will make a brand new fuel pump appear non-functional, leading to a frustrating and incorrect diagnosis. It’s always best to diagnose the system correctly before replacing parts.
Is this part compatible with other GM part numbers?
Yes. This module is a direct replacement for several original equipment part numbers, including 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, and 25866052. It functions identically to the original part 25967325.
What information do you need from me to program the module?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. This allows us to flash the module with the exact software and calibration file that GM specifies for your truck’s configuration.
