Restore Your Truck’s Power and Reliability
Is your 2010-2012 Silverado 1500 suddenly stalling, struggling to start, or showing a ‘Service StabiliTrak’ message along with poor engine performance? 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 this exact scenario countless times. The FSCM is the brain that tells the fuel pump how much pressure to deliver. When it fails, it starves your engine of fuel, leading to a host of frustrating and potentially dangerous issues.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost of dealership programming out of the equation. Simply provide us with your vehicle’s VIN at checkout, and we will flash this module with the latest, most stable GM software specific to your truck. This ensures seamless communication with your vehicle’s computer systems and restores performance to factory specifications. This is the smart, efficient fix for both seasoned mechanics and first-time DIYers.
A Technician’s Notebook: The P069E Code Mystery
I remember a 2011 Sierra 1500 that came into the bay on a tow truck. The owner had already replaced the fuel pump himself, but the truck still wouldn’t start. He was frustrated and out a few hundred dollars. A quick scan showed a persistent DTC P069E, indicating a fault in the FSCM control circuit. These modules, especially on GM trucks, are exposed to the elements on the frame rail and are a common failure point. We installed one of our pre-programmed modules, and the truck fired right up on the first try. The customer could have saved himself a weekend of frustration and the cost of a fuel pump by diagnosing the FSCM first.
Is Your Truck Showing These Symptoms?
A faulty FSCM can mimic a bad fuel pump. If you’re experiencing any of the following, this module is the likely solution for your 2010-2012 Silverado 1500 FSCM problem:
- ✔ Engine cranks but will not start
- ✔ Stalling while driving, especially under load
- ✔ Hesitation or sputtering during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
A Straightforward Guide to Installation
You can get your truck back on the road in under an hour with basic hand tools. This is a common repair for any DIY enthusiast.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most Silverado/Sierra trucks, the FSCM is mounted to the driver-side frame rail, typically near the spare tire.
- Disconnect and Remove: Unplug the electrical connectors. Be gentle with the locking tabs. Then, remove the bolts holding the module to the frame.
- Install the New Module: Bolt your new, pre-programmed FSCM into place. Ensure it’s secure.
- Reconnect: Plug the electrical connectors back into the new module. You should hear a ‘click’ as they lock in.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful.

Frequently Asked Questions
Why do you need my VIN?
Your VIN is essential for us to program the module with the exact software and calibrations your vehicle requires from the factory. This ensures perfect compatibility and prevents communication errors.
Is this part difficult to install?
No, this is a very straightforward repair for most DIYers. It typically involves unplugging the old module and bolting the new one in its place on the frame rail. No special tools are needed.
What does the Fuel System Control Module (FSCM) do?
The FSCM acts as a dedicated computer for your fuel pump. It receives commands from the main Engine Control Module (ECM) and precisely controls the voltage sent to the fuel pump to regulate fuel pressure for optimal efficiency and performance.
Will this fix a P069E code?
Yes, in my experience, a faulty FSCM is the most common cause of a P069E diagnostic trouble code on these GM trucks. Replacing it with our pre-programmed unit is the definitive fix for this issue.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part. Each unit is verified to be fully functional before being programmed with the latest GM software for your specific vehicle.
