Is your 2010-2012 GMC Canyon or other GM vehicle suddenly stalling, hesitating, or refusing to start? Before you condemn the fuel pump, the real problem is often the small electronic brain that controls it: the Fuel System Control Module (FSCM). I’ve seen it countless times in my 20+ years of diagnostics—a perfectly good fuel pump gets replaced, but the problem persists. The issue is that a new module needs to be programmed to your vehicle’s specific VIN, a step that often requires an expensive trip to the dealership. We solve that problem for you.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine quality FSCM and flash it with the latest official GM software updates tailored specifically to your truck’s VIN. This ensures flawless communication with your vehicle’s computer, restores proper fuel pressure, and resolves those frustrating drivability issues for good. By providing us with your VIN at checkout, you get a part that’s truly plug-and-play, saving you time, money, and the headache of a dealership visit.
From the Diagnostic Bay: The Ghost in the Machine
A customer brought in his 2011 Sierra with a classic complaint: it would randomly enter ‘Reduced Engine Power’ mode and sometimes stall at red lights. He’d already spent a fortune replacing the in-tank fuel pump, but the problem didn’t go away. His scanner showed a U0109 code (Lost Communication With Fuel Pump Control Module). The FSCM on these GM trucks is mounted on the frame rail, exposed to water, salt, and vibration. Corrosion had worked its way into the module’s connector, causing intermittent connection loss. We installed one of our pre-programmed modules, and the truck has run perfectly ever since. It’s a textbook example of why diagnosing the entire system, not just the loudest part, is key.
Common Signs of a Failing FSCM
If you’re experiencing any of the following, a faulty FSCM is a likely suspect. This is especially true if you’ve already checked the fuel pump and its wiring.
- âś” Check Engine Light (CEL) is on
- âś” “Reduced Engine Power” message displayed on the dash
- âś” Engine cranks but will not start
- âś” Intermittent stalling, especially under load or at idle
- âś” Vehicle hesitation or sputtering during acceleration
- âś” Common Diagnostic Trouble Codes (DTCs) stored, such as P069E, U0109, P0230, or P0606.
Your Direct-Fit Installation Guide
Installing your new 2010-2012 Canyon FSCM is a straightforward job that most DIYers can handle in their driveway. For the GMC Canyon, the module is typically located on the rear center frame crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FSCM mounted to the frame. On many GM trucks and SUVs, it’s on the driver-side frame rail, but on the Canyon/Colorado, it’s often on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connector. You may need to press a release tab. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt your new, pre-programmed FSCM into the same location. Ensure it’s secure.
- Reconnect: Plug the electrical connector firmly into the new module. You should hear a click.
- Final Step: Reconnect the negative battery terminal. Start the vehicle and check for proper operation and ensure the Check Engine Light is off.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact, most current GM software for your truck’s specific configuration. This ensures the module works correctly right out of the box and communicates properly with the engine computer, preventing compatibility issues.
Is this part difficult to install?
Not at all. For most DIYers with basic hand tools, this is a simple bolt-off, bolt-on job. The module is typically mounted on the vehicle’s frame and is easy to access. Our pre-programming means no special electronic tools are needed for the installation.
What happens if I install this without programming?
An unprogrammed FSCM will likely not work. It may cause a no-start condition, set trouble codes, or not communicate with the vehicle’s other computers. Our service eliminates this problem entirely.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part that has been electronically restored with new, vehicle-specific programming. It provides OEM performance and reliability without the high dealership price.
Will this fix a P069E code?
Yes, in many cases. The DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is a very common code pointing directly to a fault within the FSCM. Replacing a faulty module with our programmed unit is the correct repair for this code.
