Restore Power and Reliability to Your GM Vehicle
Is your 2010-2012 GMC Yukon, Tahoe, or Sierra suddenly stalling, refusing to start, or showing a ‘Reduced Engine Power’ message? Before you condemn the fuel pump, the real culprit is often the Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen countless dollars wasted on unnecessary fuel pump replacements when this module was the simple, underlying issue. This genuine GM FSCM, part number 20877116, is your direct-fit, reliable solution.
A 2011 Sierra 1500 came into the bay with a classic complaint: it would crank but not start, but only intermittently. The owner had already replaced the fuel pump himself, but the problem persisted. His scanner showed a P069E code—Fuel Pump Control Module Requested MIL Illumination. Instead of just throwing another part at it, we checked the power and ground at the FSCM connector on the frame rail. Everything looked good. The issue was internal to the module itself; it was failing under load, especially in hot weather. We installed a new, pre-programmed 2010-2012 Yukon FSCM, and the truck fired up instantly. It’s a textbook case of why proper diagnosis, and starting with the most common failure point, saves time and money.
Is Your Vehicle Showing These Telltale Signs?
A failing FSCM can manifest in several ways that are often mistaken for a bad fuel pump or other issues. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent stalling or engine hesitation, especially during acceleration.
- ✔ Crank-no-start condition where the engine turns over but won’t fire.
- ✔ ‘Reduced Engine Power’ warning light illuminated on the dash.
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or P2635.
- ✔ A fuel pump that seems to run erratically or not at all.
The Plug-and-Play Advantage: No Dealer Visit Required
The biggest challenge with replacing modern vehicle electronics is the need for expensive, proprietary programming. We eliminate that headache entirely. When you order this 2010-2012 Yukon FSCM, we flash it with the latest official GM software specifically matched to your vehicle’s VIN. This means the module arrives at your door ready for installation. You can bypass the dealership, save on programming fees, and get your truck or SUV back on the road in minutes, not days.
A Straightforward Guide to Installation
For most trucks and SUVs like the Yukon, Tahoe, and Silverado, this is a very accessible DIY job. You’ll just need basic hand tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On most compatible trucks and SUVs, you will find the FSCM mounted to the driver’s side (LH) frame rail, typically near the spare tire. On cars, it may be in the trunk or rear compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the old module from its mounting bracket on the frame. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt your new, pre-programmed FSCM into place. Reconnect the electrical connectors, ensuring they click securely into place.
- Final Step: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting the engine to allow the system to initialize. Your vehicle is now ready to drive.

Frequently Asked Questions
What does ‘pre-programmed to my VIN’ mean?
It means we load the specific software and calibrations for your exact vehicle onto the module before we ship it. This makes it a true plug-and-play part, saving you a costly trip to the dealership for programming.
Where is the FSCM located on my 2011 GMC Yukon?
On the 2010-2012 GMC Yukon and similar GM trucks/SUVs, the Fuel System Control Module is typically mounted on the inside of the driver’s side frame rail, often near or just ahead of the spare tire.
Is this part the same as a fuel pump driver module?
Yes. Fuel System Control Module (FSCM) and Fuel Pump Driver Module (FPDM) are different names for the same component. It controls the voltage sent to the fuel pump.
Do I need any special tools to install this?
No special tools are required. Basic hand tools like a socket set and ratchet are all you need for the physical installation. Because we pre-program it, you also don’t need any diagnostic scan tools for software setup.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your module without it.
