Is Your 2009 Acadia 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 failing Fuel Pump Control Module (FPCM) is a very likely culprit. This critical component, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel pump. It regulates the voltage sent to the pump, ensuring your engine receives the precise amount of fuel it needs under all driving conditions. When it fails, it can leave you stranded with symptoms that mimic a bad fuel pump, leading to costly and incorrect repairs.
Don’t guess with your vehicle’s reliability. This is a direct-fit replacement FPCM, part number 20759945, that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We handle the complex programming for you, loading the latest GM software updates to ensure optimal performance and longevity. This means no expensive trips to the dealership for flashing, no special tools required—just a straightforward installation to get you back on the road quickly and confidently.
From the Diagnostic Bay
We had a 2009 GMC Yukon come in on a tow truck. The owner was convinced his fuel pump had died—the engine would crank but never fire up. He had already replaced the pump himself, but the problem persisted. After hooking up our scan tool, we saw no communication with the FPCM and a specific diagnostic trouble code, P069E. Instead of another expensive fuel pump job, we checked the module located on the frame rail. It was heavily corroded from road salt and moisture. We installed a new, pre-programmed module, and the truck fired up on the first try. It’s a classic case where diagnosing the controller saved the customer hundreds of dollars and a lot of frustration.
Common Symptoms of a Failing 2009 Acadia Fuel Pump Module
A faulty FPCM can manifest in several ways. If you’re noticing any of the following issues, it’s time to inspect your module:
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or at idle due to inconsistent fuel pressure.
- ✔ No-Start Condition: The engine cranks over but won’t start because the fuel pump isn’t being activated.
- ✔ Hesitation or Stumbling: The vehicle may hesitate or stumble during acceleration as the engine is starved for fuel.
- ✔ Check Engine Light: You may see a Check Engine Light with codes such as P069E, P0230, P025A, or U0109, all pointing to issues within the fuel pump control circuit.
- ✔ Reduced Power: The vehicle may enter a reduced power mode to protect the engine.
- ✔ Loud Fuel Pump Noise: The FPCM may send a constant full voltage to the pump, causing it to run loudly and wear out prematurely.
The Plug-and-Play Solution
The biggest hurdle in replacing an FPCM has always been the need for dealership-level programming. We eliminate that step entirely. By providing us with your VIN during checkout, we can flash the module with the correct calibration file for your exact vehicle. This ensures seamless integration with your Powertrain Control Module (PCM) and other vehicle systems. It’s a true plug-and-play solution designed for both professional technicians and savvy DIY-ers.
This module is a direct replacement for a wide range of GM trucks and SUVs and is compatible with the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. Please verify fitment for your specific vehicle before ordering.
Frequently Asked Questions
Do I need to program this module?
No. This Fuel Pump Control Module comes fully programmed to your vehicle’s VIN. Simply provide your VIN at checkout, and we will flash the module with the latest GM software before shipping. It will be ready for installation right out of the box.
Where is the FPCM located on my 2009 Acadia?
On the 2009 GMC Acadia, the FPCM is typically located on the rear subframe or crossmember, near the fuel tank. On many GM trucks and SUVs like the Tahoe or Silverado, it’s mounted to the driver’s side frame rail. Always consult a service manual for the exact location on your vehicle.
What causes a Fuel Pump Control Module to fail?
The most common causes of failure are exposure to the elements. Since these modules are often mounted on the vehicle’s frame, they are susceptible to corrosion from water, road salt, and dirt. Electrical issues, such as voltage spikes or shorts, can also damage the internal circuitry.
Is this a genuine GM part?
This is a high-quality replacement part that is built to meet or exceed original equipment specifications. We use genuine GM software for programming to ensure perfect compatibility and performance.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the specific software calibration file for your vehicle’s exact configuration (engine, transmission, emissions, etc.). Programming the module with this file ensures it communicates correctly with your vehicle’s computer systems.
