Restore Your Escalade’s Performance and Reliability
Is your 2008-2009 Cadillac Escalade ESV experiencing frustrating issues like engine stalling, hesitation during acceleration, or a dreaded no-start condition? These are classic signs of 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 correct amount of fuel under all driving conditions. When it fails, it can leave you stranded and facing a complex repair.
We take the guesswork and high costs out of the equation. This module, part number 25854536, is a direct-fit replacement for your original. The best part? We professionally program (flash) it with the latest GM software specifically for your vehicle’s VIN before it ships. This means no expensive trip to the dealership for programming is required. It arrives at your door ready for a straightforward installation, getting you back on the road quickly and confidently.
From the Diagnostic Bay
I remember a 2008 Silverado that came into the shop on a tow truck. The owner had already replaced the fuel pump, thinking that was the issue, but it still wouldn’t start. The fuel pressure was erratic. A quick scan showed DTC P069E – Fuel Pump Control Module Requested MIL Illumination. Instead of just throwing another part at it, we checked the FPCM, which is mounted on the frame rail. It was heavily corroded from years of exposure to road salt and moisture. A new, pre-programmed module like this one had the truck running perfectly in under 30 minutes. It’s a common failure point, and having a VIN-programmed module on hand saves immense time and hassle.
Is Your Escalade Showing These Signs?
A failing FPCM can cause a variety of symptoms that are often misdiagnosed as a bad fuel pump. If you’re experiencing any of the following, this module is the likely solution for your 2008-2009 Escalade ESV FPCM problems:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Severe engine hesitation or sputtering
- ✔ Reduced engine power and poor acceleration
- ✔ Check Engine Light (CEL) is on
- ✔ Diagnostic Trouble Codes (DTCs) such as P069E, P0230, P0627, or U0109
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIY mechanics can handle with basic tools. Because this module comes pre-programmed, you skip the most difficult step. Always consult a service manual for your specific vehicle, but here is a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most GM trucks and SUVs like the Escalade, the FPCM is mounted to the driver’s side frame rail, typically near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle to avoid breaking the locking tabs. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a penetrating oil may be helpful.
- Install the New Module: Bolt the new, pre-programmed FPCM into the same location. Ensure it is securely fastened.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock into place.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful.

Frequently Asked Questions
Do I need to do any programming after I receive this module?
No. We program the module to your vehicle’s specific VIN before we ship it. It is ready for installation right out of the box, saving you a trip to the dealership.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive your VIN for programming.
Where is the FPCM located on my 2009 Escalade ESV?
On the 2008-2009 Escalade ESV, the Fuel Pump Control Module is typically mounted on the outside of the driver-side frame rail, located above the spare tire.
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 for this component.
What happens if I install this without programming?
An unprogrammed module will not work correctly. It may prevent the vehicle from starting or cause poor performance because it lacks the specific software instructions for your vehicle’s fuel system. That’s why our pre-programming service is essential.
