Restore Your Truck’s Fuel System Performance
Is your 2008-2009 Chevrolet Suburban 1500, or another compatible GM truck, suddenly stalling, hesitating, or refusing to start? Before you condemn the in-tank fuel pump, the culprit is often the Fuel Pump Control Module (FPCM), also known as the Fuel System Control Module (FSCM). This critical component, mounted on the vehicle’s frame rail, is responsible for precisely managing the voltage sent to the fuel pump. Over time, its location exposes it to harsh elements like water, salt, and vibration, leading to internal corrosion and failure. This failure can leave you stranded with a vehicle that cranks but won’t start, or cause dangerous stalling while driving.
This replacement Fuel Pump Control Module is the definitive solution to these common issues. We take the guesswork and dealership hassle out of the repair. Unlike a standard off-the-shelf part, this module arrives at your door fully programmed with the latest GM software, specifically matched to your vehicle’s Vehicle Identification Number (VIN). This means no expensive trips to the dealer for programming are required. It’s a true plug-and-play component designed to restore factory operation and reliability, getting you back on the road with confidence.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in with a classic ‘crank, no start’ condition. The owner had already spent hundreds replacing the in-tank fuel pump himself, but the problem persisted. A quick scan showed no fuel pressure, yet the new pump was good. We immediately checked the FPCM on the driver’s side frame rail. The housing was corroded, and upon opening it, we found the circuit board was covered in green oxidation. We installed one of our VIN-programmed modules, and the truck fired up on the first try. It’s a textbook example of how diagnosing the entire system, not just the most obvious part, saves time and money. The FPCM is the brain, and when it fails, the pump can’t do its job.
Symptoms of a Failing Suburban 1500 Fuel Module
If your vehicle is exhibiting any of the following symptoms, a faulty FPCM is a highly likely cause. A failing module can mimic a bad fuel pump, so proper diagnosis is key. Look for these warning signs:
- ✔ Engine cranks but will not start.
- ✔ Vehicle stalls unexpectedly while driving, sometimes with no warning.
- ✔ Hesitation or stumbling during acceleration as the fuel demand increases.
- ✔ Reduced engine power and poor performance.
- ✔ Check Engine Light (CEL) with diagnostic trouble codes (DTCs) like P069E, P025A, or U0109.
- ✔ “Service Stabilitrak” or “Service Traction Control” messages may appear, as the fuel system is tied into vehicle stability controls.
- ✔ Inconsistent fuel pressure readings.
The VIN-Programmed Advantage
Modern GM vehicles require electronic modules to be specifically coded to the vehicle they are installed in. This 2008-2009 Suburban 1500 Fuel Module is programmed before shipment, which is a critical step. By providing us with your VIN, we ensure the module has the correct software and calibrations for your truck’s specific engine, transmission, and emissions equipment. This process prevents compatibility issues, ensures proper fuel pressure control under all operating conditions, and makes the installation process as simple as unbolting the old part and installing the new one.
Installation and Compatibility
This FPCM is a direct-fit replacement for the original GM part number 25785013 and is compatible with a wide range of other part numbers, including 13501024, 15213110, 20759945, 20850907, 25854536, 25866052, and 25967325. It fits a large family of GM trucks and SUVs, typically mounted to the driver’s side frame rail near the spare tire. Installation is straightforward for a DIY mechanic with basic tools. Simply disconnect the battery, raise the vehicle safely, unplug the electrical connectors, remove the mounting bolts, and swap the module. No special tools or programming equipment are needed on your end.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact GM factory software and calibrations for your specific truck or SUV. This ensures the module communicates correctly with your vehicle’s other computers and controls the fuel pump with perfect precision, eliminating the need for a dealership visit.
Where is the Fuel Pump Control Module located on my vehicle?
On most compatible GM trucks and SUVs like the Suburban, Tahoe, and Silverado, the FPCM is typically mounted on the driver’s side frame rail, often above or near the spare tire. Its exposed location is a primary reason for its high failure rate due to moisture and corrosion.
Is this a difficult part to replace myself?
For most individuals with basic mechanical skills, this is a very manageable job. It typically involves safely raising the vehicle, disconnecting the electrical harness, and removing a few bolts. Since our module comes pre-programmed, the most complex part of the job (the software) is already done for you.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded ON) is one of the most common codes indicating a fault within the FPCM itself. Replacing the module with this pre-programmed unit is the correct and most effective repair for this code.
Is this module compatible with other vehicles besides the Suburban?
Absolutely. This module is a direct replacement for a wide range of GM vehicles from the same era, including the Cadillac Escalade, GMC Sierra, Chevrolet Silverado, Tahoe, Yukon, and more. Please check the detailed fitment list on this page to confirm compatibility with your specific model.
