Restore Your Acadia’s Performance and Reliability
Is your 2010-2012 GMC Acadia suddenly stalling, struggling to start, or showing a check engine light? Before you condemn the fuel pump, the problem is often its electronic brain: the Fuel System Control Module (FSCM). As a technician with over 20 years of experience, I’ve seen countless drivers spend a fortune on fuel pump replacements when this module was the real, and much simpler, fix. This FSCM is the definitive solution to get your vehicle back on the road with confidence.
The biggest challenge with replacing an FSCM has always been the mandatory, and expensive, trip to the dealership for programming. We eliminate that step entirely. When you purchase this module, we flash it with the very latest GM-approved software, specifically matched to your vehicle’s VIN. It arrives at your door ready for a true plug-and-play installation. This isn’t just a part; it’s a complete, hassle-free repair solution for your 2010-2012 Acadia Fuel Control Module.
From the Diagnostic Bay: The Acadia That Wouldn’t Start
A customer brought in a 2011 Acadia with an intermittent no-start and stalling issue. They had already paid another shop to replace the in-tank fuel pump, but the problem persisted. Frustrated, they came to us. My first step was a full system scan, which immediately flagged DTC U0109 – ‘Lost Communication with Fuel Pump Control Module.’ Instead of just throwing another part at it, I checked the wiring to the FSCM on the rear crossmember. The connections were clean and tight. The issue was internal to the module itself; it was failing intermittently, starving the brand-new fuel pump of power. We installed one of these pre-programmed modules, and the Acadia fired up instantly and ran perfectly. The customer could have saved hundreds of dollars and a lot of headaches by starting with the right diagnosis and this exact part.
Common Signs of a Failing FSCM
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when warm
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery.
- ✔ Locate the Module: On the 2010-2012 Acadia, the FSCM is typically mounted to the rear crossmember, just ahead of the rear bumper. It’s often exposed to the elements, which contributes to its failure.
- ✔ Disconnect Electrical Connectors: Carefully press the release tabs and pull the electrical connectors straight out from the old module. Inspect them for any corrosion or damage.
- ✔ Remove the Old Module: Unbolt the old FSCM from the crossmember. These bolts can sometimes be rusty, so a little penetrating oil might be helpful.
- ✔ Install the New Module: Bolt your new, pre-programmed 2010-2012 Acadia Fuel Control Module in place of the old one.
- ✔ Reconnect Everything: Securely plug in the electrical connectors until they click. Reconnect the negative battery terminal.
- ✔ Final Check: Start the vehicle. It should fire up and run smoothly, with the check engine light off.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. This is the key benefit of our service. The module arrives at your doorstep fully programmed with the latest GM software for your specific vehicle. It’s ready to install right out of the box.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the exact factory software and calibration files for your vehicle’s specific configuration. This ensures perfect communication between the FSCM and your car’s other computers.
Where is the FSCM located on a 2011 Acadia?
On the GMC Acadia, Buick Enclave, and Chevy Traverse, the Fuel System Control Module is typically mounted on the vehicle’s rear crossmember, making it relatively easy to access from underneath the vehicle.
Is this the same as a fuel pump?
No. This module is the computer that *controls* the fuel pump. It tells the pump when to run and at what speed to maintain correct fuel pressure. A bad module can make a perfectly good fuel pump appear to be faulty.
Will this fix a P069E code?
Yes, a faulty FSCM is the most common cause of the DTC P069E (Fuel Pump Control Module Requested MIL Illumination). Replacing the module with this pre-programmed unit is the correct repair for that code, assuming wiring is intact.
