Restore Your Yukon’s Performance & Reliability
Is your 2010-2012 GMC Yukon experiencing frustrating issues like stalling, hesitation, a no-start condition, or a persistent check engine light? Before you assume it’s the fuel pump, the real culprit is often a faulty Fuel System Control Module (FSCM). As a technician with over 20 years of experience, I’ve seen this exact scenario countless times. This module is the brain of your fuel delivery system, and when it fails, it can leave you stranded. We offer a dependable, direct-fit solution: a replacement FSCM, part number 20827745, that arrives at your door pre-programmed for your specific vehicle.
From the Diagnostic Bay
I remember a 2011 Yukon that came into my shop. The owner had already spent a small fortune replacing the in-tank fuel pump, but the truck would still randomly stall at red lights. His scanner showed a P069E code, which points to the FSCM. The original module, exposed to years of road salt and moisture on the frame rail, had failed internally. We installed one of our pre-programmed modules, and the problem was solved in under 30 minutes. This isn’t just a part; it’s a permanent fix that saves you from chasing the wrong diagnosis and wasting money.
Is Your Vehicle Showing These Signs of a Bad FSCM?
A failing Fuel System Control Module can mimic other fuel system problems. Here are the most common symptoms and diagnostic trouble codes (DTCs) to look for:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Rough idling or engine hesitation
- ✔ Reduced engine power and poor acceleration
- ✔ Check Engine Light on with codes like P069E, P0230, or U0109
- ✔ “Service Fuel System” message on the driver information center
A Straightforward Guide to Installation
Replacing the FSCM on your 2010-2012 Yukon is a job most DIYers can handle with basic tools. Because our module comes pre-programmed, you skip the expensive trip to the dealership. Just install it, and you’re ready to go.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most GMT900 trucks and SUVs like the Yukon, the FSCM is mounted on the driver’s side frame rail, typically near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts securing the old module to the frame. It may be corroded, so a little penetrating oil can help.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- Reconnect and Test: Plug the electrical connectors back in firmly. Reconnect the battery terminal. Turn the key to the ‘On’ position for a few seconds to prime the system, then start the engine.

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is critical. We use it to load the exact GM-certified software and calibrations for your specific vehicle. This ensures perfect compatibility and function, eliminating the need for dealer programming.
Where is the FSCM located on my 2011 Yukon?
On the 2010-2012 GMC Yukon, the Fuel System Control Module is typically mounted to the outside of the driver-side frame rail, often above or just forward of the spare tire.
Is this a plug-and-play part?
Yes. Because we program it to your VIN before shipping, it is a true plug-and-play replacement. No additional calibration or programming is required after you install it.
My mechanic said I need part number 20791901. Will this work?
Yes, this module is a direct replacement for part numbers 20791901, 20827745, 20877116, and 20850927. It is the correct, updated component for your vehicle.
What makes this better than a used part from a junkyard?
