Is your 2009 GMC Acadia or other GM truck/SUV suddenly stalling, hesitating, or refusing to start? These are classic, frustrating signs of a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component regulates the voltage sent to your fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded without warning.
Don’t pay for expensive diagnostic time and programming fees at the dealership. We offer a reliable and straightforward solution. This is a direct-replacement FPCM that comes fully programmed with the latest GM software updates specifically for your vehicle. Simply provide your Vehicle Identification Number (VIN) after purchase, and our experts will flash the module before it ships. It arrives at your door ready for a simple, plug-and-play installation, restoring your vehicle’s performance and dependability.
Common Signs of a Failing FPCM
- ✔ Engine cranks but will not start.
- ✔ Stalling, especially under load or when warm.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor performance.
- ✔ An active Check Engine Light (CEL) with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109 (Lost Communication with Fuel Pump Control Module).
- ✔ Inconsistent fuel pressure readings.
Case Study: A Tricky Diagnosis
I had a 2008 Chevy Tahoe in the bay that was a real head-scratcher. The owner complained of intermittent stalling, but only after driving for 30+ minutes on a hot day. It would always restart after cooling down. We checked fuel pressure at the rail, and it was perfect when cold, but would drop off randomly when hot. There were no hard codes, just a pending U0109. These frame-mounted FPCMs are notorious for failing due to heat and corrosion from road debris. After swapping in a new, programmed module, the problem was solved for good. It’s a textbook example of how heat-soak can expose a failing electronic component.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the Module: On most GM trucks and SUVs (like the Tahoe or Sierra), the FPCM is mounted to the driver-side frame rail, often near the spare tire. On vehicles like the Acadia or Traverse, it’s typically on a rear crossmember. Always consult a service manual for your specific vehicle’s location.
- ✔ Disconnect and Remove: Unplug the electrical connector(s) by depressing the locking tab. Then, remove the bolts or nuts holding the old module to the frame. These can sometimes be corroded, so a little penetrating oil can help.
- ✔ Install the New Module: Mount your new, pre-programmed FPCM in the same location and tighten the fasteners securely. Reconnect the electrical harness, ensuring it clicks into place.
- ✔ Final Steps: Reconnect the negative battery terminal. Prime the fuel system by turning the key to the ‘On’ position (without starting) for a few seconds, then turning it off. Repeat this 2-3 times before starting the engine. Clear any old DTCs with a scan tool.

Frequently Asked Questions
Do I need to do any programming myself?
No. This module is professionally flashed with the latest GM software before we ship it. It is matched to your vehicle using the VIN you provide, making it a true plug-and-play part.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Why is a programmed module better than a used one?
A used module may have outdated software and is likely near the end of its service life. Our modules are loaded with the newest software updates from GM, which often correct factory flaws and improve performance and reliability.
What tools are needed for installation?
For most installations, you’ll only need basic hand tools, such as a socket set and ratchet to remove the mounting bolts and a small screwdriver to help release the electrical connector tab. No special electronic tools are required.
Is this part compatible with other part numbers?
Yes, this FPCM, 25866052, is a direct replacement for several other GM part numbers, including 13501024, 20759945, 25854536, and others listed in the description, ensuring wide compatibility.
