Restore Your Truck’s Performance and Reliability
Is your 2010-2012 Chevrolet Avalanche or other GM vehicle experiencing frustrating issues like stalling, hesitation, or a complete no-start condition? A faulty Fuel System Control Module (FSCM) is one of the most common culprits. This module acts as the brain for your fuel pump, regulating voltage to ensure your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded and scratching your head. This isn’t just an inconvenience; it’s a critical component for engine performance and reliability.
We offer a dependable, plug-and-play solution. This Fuel System Control Module is a direct-fit replacement, but with one crucial advantage: it arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. Simply provide your VIN during checkout, and our experts will handle the rest, ensuring a seamless installation and immediate results.
Case Study: The Ghost in the Fuel System
I remember a 2011 Silverado 1500 that came into the shop a few years back. The owner was at his wit’s end. He’d already replaced the fuel pump twice at another garage, but the truck would still intermittently lose power and stall, throwing a P069E code (Fuel Pump Control Module Commanded Performance). The fuel pressure would test fine one minute and drop off the next. Instead of throwing another pump at it, we focused on the controller. The original FSCM, exposed to years of road grime and moisture on the frame rail, had developed an internal fault. We installed one of our pre-programmed modules, matched to his VIN. The truck fired right up and the P069E code never came back. It’s a classic example of why diagnosing the ‘brain’ is just as important as checking the ‘heart’ of the fuel system.
Is Your Truck Showing These Telltale Signs?
A failing FSCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Reduced engine power and poor acceleration
- ✔ Rough or erratic idle
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication with FSCM)
A Straightforward Guide to Installation
Replacing the 2010-2012 Avalanche FSCM is a job most DIYers can handle with basic tools. On most GM trucks and SUVs, it’s located on the driver’s side frame rail, near the spare tire.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: Find the old FSCM mounted to the frame rail. It’s a small black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the module from the frame. It’s typically held on by two bolts.
- Install the New Module: Bolt the new, pre-programmed FSCM into the same location. Ensure it’s secure.
- Reconnect and Test: Plug the electrical connectors firmly into the new module. Reconnect your battery terminal. Start the vehicle to confirm the repair.

Frequently Asked Questions
What does a Fuel System Control Module (FSCM) do?
The FSCM, sometimes called a Fuel Pump Driver Module, is a small computer that controls the voltage sent to your vehicle’s electric fuel pump. This allows it to precisely manage fuel pressure for optimal engine performance and efficiency.
Do I really need to provide my VIN?
Yes. Providing your VIN is essential. We use it to load the correct, vehicle-specific GM software onto the module before shipping. This ensures it communicates properly with your vehicle’s other computers and functions correctly right out of the box.
Will this fix my P069E check engine light code?
In many cases, yes. The DTC P069E is a very common indicator of a failing FSCM. While other issues can cause this code, a faulty module is the most frequent cause, especially if you’re also experiencing stalling or no-start symptoms.
Is this a brand new part?
This is a high-quality, tested, and verified used component that has been professionally programmed with the latest software for your vehicle. It provides a reliable and cost-effective alternative to a new dealership part.
Where is the FSCM located on a 2011 Silverado or Tahoe?
On most GM trucks and SUVs of this era, including the Silverado, Tahoe, Suburban, and Avalanche, the FSCM is mounted on the driver’s side frame rail, often above or near the spare tire.
