Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re experiencing frustrating fuel delivery issues with your 2009 GMC Acadia or another compatible GM vehicle, a faulty Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is a highly probable cause. This critical component is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded with symptoms ranging from a simple check engine light to a vehicle that won’t run at all. This replacement module, part number 25866052, is the definitive solution to restore your vehicle’s reliability and performance.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in with a classic ‘crank, no start’ condition. The owner had already replaced the fuel pump himself, assuming it was the culprit, but the problem persisted. A quick scan revealed trouble code P069E – ‘Fuel Pump Control Module Commanded OFF’. Instead of throwing more parts at it, we inspected the FPCM located on the frame rail. It was heavily corroded from years of exposure to road salt and moisture. We installed one of our pre-programmed modules, cleared the codes, and the truck fired right up. It’s a textbook example of how diagnosing the control side of the circuit first can save hundreds of dollars and hours of frustration.
The Importance of a Programmed 2009 Acadia Fuel Pump Module
In modern vehicles, the FPCM isn’t just a simple relay; it’s a computer that communicates with the Engine Control Module (ECM) to deliver the exact amount of fuel needed for any given driving condition. This variable-pressure system improves efficiency and prolongs the life of the fuel pump. However, this complexity means you can’t just swap in a used module from another vehicle. Each FPCM is calibrated to the specific vehicle it’s installed in. Our service eliminates this headache. We flash this module with the latest official GM software specifically for your vehicle’s VIN. This ensures perfect communication, correct fuel pressure, and a true plug-and-play installation, saving you a costly trip to the dealership for programming.
Common Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start.
- ✔ Stalling, especially under load or when coming to a stop.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor performance.
- ✔ Check Engine Light illuminated with codes like P069E, P0230, or U0109.
- ✔ A loud whining noise from the fuel pump as it runs continuously at full power.
- ✔ Inconsistent fuel pressure readings.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This makes the installation plug-and-play, saving you time and the expense of a dealership visit.
What are the most common trouble codes for a bad FPCM?
The most common diagnostic trouble code (DTC) is P069E. You may also see codes like P0230 (Fuel Pump Primary Circuit Malfunction) or U0109 (Lost Communication With Fuel Pump Control Module), indicating either an electrical or communication fault with the module.
Where is the Fuel Pump Control Module located?
Location varies by model. On most GM trucks (Silverado, Sierra, Avalanche, Escalade), it’s mounted on the driver’s side frame rail, often near the spare tire. On SUVs like the Acadia, Traverse, and Enclave, it’s typically located on or near the rear subframe, close to the fuel tank. It’s often exposed to the elements, which contributes to its failure.
How do I provide my VIN for programming?
After you complete 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 part to function correctly.
Is it possible the fuel pump is bad and not the module?
Yes, it’s possible. However, the FPCM is a very common failure point on these vehicles, especially if you have the P069E code. A good diagnostic step is to check for power at the fuel pump connector. If the module is receiving power and has good ground but is not sending voltage to the pump, the module is almost certainly the culprit.
