Is Your GM Vehicle Stalling, Sputtering, or Refusing to Start?
A faulty Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM), is a common and often misdiagnosed issue on many 2007-2009 GM trucks and SUVs, including your 2009 GMC Acadia. This critical component is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded with a vehicle that cranks but won’t start, or cause dangerous stalling and hesitation while driving. Don’t waste money replacing a perfectly good fuel pump—address the root cause with this direct-fit, pre-programmed FPCM.
From the Diagnostic Bay
We had a 2008 Silverado in the shop that was on its third fuel pump in a year. The owner was frustrated, and rightfully so. The truck would run fine for a few weeks, then suddenly start to sputter and die at stoplights. Each time, the previous shop just threw a pump at it. We hooked up our diagnostic scanner and monitored the fuel pump command and feedback signals. We saw the FPCM was erratically commanding the pump, sometimes cutting power entirely. The tell-tale code was P069E stored in the ECM. We installed a new, properly programmed FPCM, and the truck has been running perfectly ever since. It’s a classic case of diagnosing the brain, not just the muscle.
Common Symptoms of a Failing FPCM
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, often when coming to a stop or under load
- ✔ Hesitation or sputtering during acceleration
- ✔ Reduced engine power or the vehicle entering ‘limp mode’
- ✔ An illuminated Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109
- ✔ A buzzing or whining noise from the fuel pump area that is inconsistent
The Plug-and-Play Solution: A Pre-Programmed 2009 Acadia Fuel Pump Module
The biggest challenge when replacing an FPCM is the required programming. Traditionally, this meant having your vehicle towed to a dealership for a costly programming session. We eliminate that step entirely. This module is not just a part; it’s a complete solution. When you purchase from us, you provide your vehicle’s 17-digit Vehicle Identification Number (VIN). Our certified technicians will then flash the module with the latest, most stable GM-approved software specific to your exact vehicle configuration. This ensures perfect communication between the FPCM, the Engine Control Module (ECM), and the fuel pump, restoring factory performance and reliability.
This module, part number 20850907, is a direct replacement for a wide range of original part numbers, including 13501024, 15213110, 20759945, 25785013, 25854536, 25866052, and 25967325. It fits an extensive list of GM vehicles, making it a versatile and reliable fix for models like the Chevrolet Tahoe, Silverado, Suburban, GMC Sierra, Cadillac Escalade, and many more. Please verify the fitment list to ensure compatibility.
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not. The main benefit of our service is that we handle all the programming for you before we ship the part. Simply provide your VIN during checkout, and the module will arrive at your door ready for a plug-and-play installation.
Where is the FPCM located on my 2009 GMC Acadia?
On the 2009 Acadia, as well as the Traverse and Enclave, the Fuel Pump Control Module is typically located on or near the rear subframe/crossmember. On GM trucks and full-size SUVs, it is most often found on the driver’s side frame rail, near the spare tire.
What happens if I install this without programming?
An unprogrammed FPCM will not work. The module needs the specific software for your vehicle’s VIN to communicate with the ECM and other vehicle systems. Your vehicle will not start or run correctly with a blank module. This is why our pre-programming service is essential.
Will this fix a P069E trouble code?
A P069E code (Fuel Pump Control Module Commanded Performance) is one of the most common indicators of a failing FPCM. While you should always perform a complete diagnosis, a faulty module is the leading cause for this specific code, and replacing it with this pre-programmed unit is the most effective repair.
Is this an authentic GM part?
This is a high-quality, direct-fit replacement module. We program it using official GM software and calibration files to ensure it functions identically to the original equipment and meets or exceeds factory specifications for performance and reliability.
