Restore Your Vehicle’s Fuel System Performance
Is your GM truck or SUV stalling, hesitating, or refusing to start? The problem may not be your fuel pump, but the electronic brain that controls it: the Fuel Pump Control Module (FPCM). This critical component, also known as a Fuel System Control Module (FSCM), regulates the voltage sent to the fuel pump, ensuring your engine receives the precise amount of fuel it needs for any driving condition. When it fails, it can cause a wide range of frustrating and debilitating drivability issues, often leading to a misdiagnosis of a bad fuel pump.
This replacement FPCM, part number 25866052, is the definitive solution for a faulty original module. Unlike parts that require an expensive trip to the dealership for calibration, this module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load the latest GM-certified software updates, which can correct factory flaws and improve overall fuel system stability. This makes for a simple, direct-fit, plug-and-play installation that you can perform right in your own driveway.
From the Diagnostic Bay
We recently had a 2008 Silverado 1500 towed in with a classic ‘crank-no-start’ condition. The owner had already spent hundreds of dollars replacing the in-tank fuel pump assembly, convinced it was the culprit. When the new pump didn’t solve the problem, he was at his wit’s end. A quick diagnostic scan showed code P069E – ‘Fuel Pump Control Module Commanded OFF.’ We put the truck on the lift and found the original FPCM on the driver’s side frame rail, its aluminum casing swollen and corroded from years of exposure to road salt and moisture. We installed one of our pre-programmed modules, and the truck fired up on the first try. The customer could have saved himself a lot of time and money by checking this common failure point first.
Symptoms of a Failing GM Fuel Pump Module
If your vehicle is exhibiting any of the following symptoms, a failing FPCM is a highly likely cause. A faulty module can mimic a bad fuel pump, so it’s crucial to diagnose the system correctly.
- ✔ Engine cranks but will not start
- ✔ Stalling or shutting off while driving, especially when warm
- ✔ Severe hesitation or sputtering during acceleration
- ✔ Reduced engine power and poor performance
- ✔ Check Engine Light illuminated with fuel-related diagnostic trouble codes (DTCs) such as P069E, P0230, or P025A
- ✔ ‘Service Fuel System’ message appearing on the driver information center
- ✔ A buzzing or whining noise from the fuel pump that is inconsistent
The Importance of VIN Programming
Modern vehicles use complex networks of modules that communicate with each other. The FPCM needs to be perfectly matched to your vehicle’s engine, transmission, and emissions equipment to function correctly. Simply installing a used or non-programmed module will result in a no-start condition and communication errors. Our process eliminates this hurdle. By providing your VIN during checkout, you ensure that the GM Fuel Pump Module you receive is loaded with the correct software for your exact build. This guarantees seamless integration and optimal performance from the moment it’s installed.
This module is a direct replacement for a wide range of original equipment part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. It fits dozens of popular GM models like the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, Cadillac Escalade, and more. Please verify fitment using the compatibility chart.
Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. The main benefit of our service is that this Fuel Pump Control Module comes fully pre-programmed to your vehicle’s VIN. It is ready for installation right out of the box, saving you the time, cost, and hassle of a dealership visit.
Where is the FPCM located on my vehicle?
On most GM trucks and full-size SUVs (like the Silverado, Sierra, Tahoe, Yukon), the module is mounted on the driver’s side frame rail, often above or near the spare tire. On other vehicles, its location can vary, so consulting a service manual for your specific model is always recommended.
What is a VIN and why do you need it?
The VIN, or Vehicle Identification Number, is a unique 17-digit code for your specific vehicle. It contains information about the manufacturer, model, year, and factory-installed equipment. We use this VIN to download the exact GM software calibration required for your vehicle, ensuring perfect compatibility and function.
Will this fix my check engine light for code P069E?
Code P069E (‘Fuel Pump Control Module Commanded OFF’) is one of the most common codes indicating a failed FPCM. While other issues like wiring problems can cause this code, a faulty module is the most frequent cause. Replacing the module with this programmed unit is the correct repair in the vast majority of cases.
Is this a new or used part?
This is a high-quality, fully tested, and guaranteed-to-function component. Each module undergoes a rigorous inspection and programming process to ensure it meets or exceeds original equipment performance standards.
How long does the installation take?
For a DIY mechanic with basic tools, the installation process typically takes less than 30 minutes. It involves safely raising the vehicle, locating the module, disconnecting the battery, unplugging the electrical connector, unbolting the old module, and installing the new one in its place.
