Restore Your Truck’s Performance with a VIN-Programmed FPCM
Is your 2008-2009 Cadillac Escalade EXT, or another compatible GM truck, experiencing frustrating issues like stalling, hesitation, or a complete failure to start? Before you condemn the fuel pump, the culprit is often the 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 optimal fuel pressure and engine performance under all driving conditions. When it fails, it can leave you stranded and cause a cascade of confusing symptoms.
From the Diagnostic Bay
We recently had a 2008 Sierra 1500 towed in that was on its third fuel pump in six months. The owner was convinced he kept getting faulty pumps. The truck would crank fine but wouldn’t start, or it would die intermittently while driving. After connecting our diagnostic scanner, we saw no communication with the FPCM and a P069E code stored in the ECM. A quick check of the module, located on the frame rail, revealed significant corrosion on the housing. The original module had failed, and the un-programmed replacement modules he was installing couldn’t properly command the new pumps, leading him to believe the pumps were bad. We installed a single VIN-programmed FPCM, and the truck fired up instantly with perfect fuel pressure. It’s a classic case of misdiagnosis that costs vehicle owners time and money.
Common Symptoms of a Failing FPCM
A faulty fuel pump control module can mimic a bad fuel pump, leading to costly and incorrect repairs. If your vehicle is showing any of these signs, it’s time to inspect the FPCM:
- ✔ Engine cranks but refuses to start.
- ✔ Vehicle stalls unexpectedly, especially when warm or under load.
- ✔ Noticeable hesitation or sputtering during acceleration.
- ✔ Reduced engine power and performance.
- ✔ An active Check Engine Light with codes such as P069E, P0230, or P025A.
- ✔ A fuel pump that seems unusually loud or whines constantly.
The Critical Role of the Escalade EXT Fuel Pump Module
Unlike older systems that simply turn the fuel pump on or off, modern GM vehicles use this sophisticated module to vary the fuel pump’s speed. This Pulse Width Modulation (PWM) control allows for more precise fuel delivery, better fuel economy, and longer pump life. However, these modules are often mounted on the vehicle’s frame rail, where they are exposed to water, salt, and vibrations, leading to premature failure. This specific Escalade EXT Fuel Pump Module is the brain of your fuel system, and when it malfunctions, the entire system is compromised.
The Plug-and-Play Solution: Pre-Programmed for Your VIN
Replacing the FPCM isn’t as simple as just swapping the part. These modules are vehicle-specific and require programming to communicate with your truck’s Engine Control Module (ECM) and other systems. Without proper programming, a new module will not function. Our service eliminates this hassle entirely. When you purchase from us, you provide your vehicle’s VIN, and we flash the module with the latest, most stable GM-approved software specifically for your truck. This ensures:
- Guaranteed Compatibility: The module is programmed to your exact vehicle configuration.
- No Dealer Visit Needed: Save hundreds of dollars in dealership programming fees and towing costs.
- Easy Installation: Once you receive the part, it’s a true plug-and-play installation. Simply bolt it on and connect the harness.
- Optimal Performance: The newest software updates from GM address known bugs and improve fuel system operation.
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 a vast array of GM trucks and SUVs from the 2007-2009 era, making it a versatile and essential component for many owners.

Frequently Asked Questions
Do I need to get this module programmed?
No. We handle all the programming for you before the part is shipped. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and the module will arrive ready for a plug-and-play installation.
Where is the FPCM located on my 2008 Escalade EXT?
On most compatible GM trucks and SUVs, including the Escalade, Tahoe, and Silverado, the Fuel Pump Control Module is typically mounted to the driver’s side frame rail, near the spare tire.
Can a bad FPCM damage my fuel pump?
Yes. A failing module can send incorrect voltage to the fuel pump, causing it to run at 100% capacity continuously or receive erratic power, both of which can significantly shorten the life of the pump motor.
Is this a genuine GM part?
Yes, this is a genuine GM component, programmed with official GM software. This ensures perfect fitment, function, and long-term reliability for your vehicle.
How do I provide my VIN for programming?
After completing your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive this information, as the programming is essential for the module to function in your vehicle.
