Restore Your GM Truck’s Fuel Delivery & Reliability
If your 2010-2012 GMC Yukon XL 1500 is experiencing frustrating issues like cranking but not starting, stalling at random, or showing a ‘Reduced Engine Power’ message, the culprit is often a failed Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen this exact scenario countless times. The FSCM is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to unreliable performance that can leave you stranded. Don’t waste money replacing a perfectly good fuel pump when the FSCM is the real problem.
This is a direct-fit, plug-and-play solution. We take all the guesswork and dealership hassle out of the equation. Before we ship this module, we program it with the latest GM software updates specifically for your vehicle using the VIN you provide. This means no expensive trips to the dealer for programming—it arrives ready to install right out of the box. This is the most efficient and cost-effective way to get your truck back to factory-spec performance and reliability. By replacing your faulty unit with our pre-programmed 2010-2012 Yukon Fuel Module, you’re not just fixing a part; you’re restoring your confidence in your vehicle.
A Technician’s Notebook: The Misdiagnosed Fuel Pump
A customer brought in his 2011 Sierra with a classic no-start condition. Another shop had already quoted him over $1,200 to replace the in-tank fuel pump. He was frustrated and looking for a second opinion. I hooked up my scan tool and saw no communication with the fuel pump control module (DTC U0109) and a low-pressure command code (P069E). Instead of dropping the tank, I went straight to the FSCM on the frame rail. It showed clear signs of water intrusion and corrosion—a common failure point. We installed a pre-programmed module, and the truck fired right up. A 15-minute fix saved him over a thousand dollars and a lot of unnecessary labor.

A Straightforward Guide to Installation
Installing your new 2010-2012 Yukon Fuel Module is a job most DIYers can handle in under 30 minutes with basic hand tools. It’s typically located on the driver’s side frame rail, making it easily accessible.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the inside of the driver-side frame rail, usually near the spare tire.
- Disconnect Wiring: Carefully press the release tabs and unplug the electrical connectors from the old module.
- Remove Old Module: Use a socket wrench to remove the bolts or nuts securing the module to the frame.
- Install New Module: Mount your new, pre-programmed FSCM in the same location and tighten the fasteners securely.
- Reconnect and Test: Plug the electrical connectors back in until they click. Reconnect the battery terminal, turn the key to the ‘On’ position for a few seconds to prime the system, and then start your engine.

Frequently Asked Questions
Why do you need my VIN?
Your VIN is required to program the module with the exact software and calibrations for your specific vehicle. This ensures perfect compatibility and function, eliminating the need for a dealer visit.
Is this a common problem on these GM trucks?
Yes, FSCM failure is a well-documented issue. The module’s location on the frame rail exposes it to moisture and road debris, which can lead to corrosion and internal failure over time.
What does the Fuel System Control Module (FSCM) do?
The FSCM, also known as a fuel pump driver module, regulates the voltage sent to the fuel pump. This controls the pump’s speed and fuel pressure to meet the engine’s demands for optimal performance and efficiency.
Can I install this myself?
Absolutely. Since the module comes pre-programmed, installation is a straightforward unbolt-and-replace process that requires only basic hand tools and can typically be completed in under 30 minutes.
Will this fix a P069E code?
A P069E code (Fuel Pump Control Module Requested MIL Illumination) very often points to a faulty FSCM. While you should always perform a full diagnosis, replacing the FSCM is the most common and effective fix for this code.
