Restore Your Tahoe’s Reliability and Performance
Is your 2010-2012 Chevy Tahoe suffering from frustrating and unpredictable issues like stalling, extended cranking times, or a complete no-start condition? 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 play out countless times. This module, often exposed to the elements on the frame rail, is a common failure point. Our solution is a dependable, pre-programmed 2010-2012 Tahoe Fuel Module that gets you back on the road without the hassle and expense of a dealership visit.
From the Diagnostic Bay: The Intermittent Stall Case
A customer brought in his 2011 Tahoe, complaining it would die randomly at stoplights and sometimes wouldn’t restart for 10-15 minutes. There were no consistent warning lights, but when I pulled the codes, I found a stored P069E – ‘Fuel Pump Control Module Commanded OFF’. While this can point to a pump, my experience screamed FSCM. These modules get battered by water, salt, and road debris. We swapped in one of our VIN-programmed modules right there in the bay. The fix was immediate and permanent. This simple replacement saved the customer from a much more expensive fuel pump job and restored his confidence in his vehicle.
Is Your Tahoe Showing These Signs of a Bad FSCM?
A failing Fuel System Control Module can mimic other problems, but it often leaves a distinct trail of clues. If you’re experiencing any of the following, a faulty FSCM is the likely cause:
- ✔ Engine stalls unexpectedly, especially at idle or low speeds.
- ✔ Vehicle cranks but refuses to start.
- ✔ Noticeable hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ An active Check Engine Light with codes such as P069E, P0230 (Fuel Pump Primary Circuit Malfunction), or U0109 (Lost Communication with FSCM).
Your Straightforward Installation Guide
One of the biggest benefits of this module is its simple, plug-and-play installation. Because we program it to your vehicle’s VIN before shipping, you don’t need any special tools or a trip to the dealer. For most GM trucks and SUVs like the Tahoe, the process is very manageable for a DIYer.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On most 2010-2012 Tahoes, you’ll find the FSCM mounted to the driver’s side (LH) frame rail, often near the spare tire.
- Remove the Old Unit: Use a socket wrench to remove the bolts securing the old module to the frame. Carefully disconnect the electrical connectors, taking note of their orientation.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location. Securely reconnect the electrical connectors until they click into place.
- Final Steps: Re-bolt the module to the frame and reconnect the negative battery terminal. Start the vehicle to confirm the repair.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during checkout, and it will arrive ready for a plug-and-play installation. This saves you time and money.
Where is the FSCM located on my 2011 Tahoe?
On the 2010-2012 Tahoe, Suburban, Yukon, and Silverado models, the Fuel System Control Module is typically mounted on the outside of the driver’s side frame rail, near the spare tire area.
How do I provide my VIN?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN to program the module correctly.
Is this the same as a fuel pump?
No. This is the electronic control module that tells the fuel pump (located in the fuel tank) how much fuel to deliver to the engine. The FSCM regulates the voltage to the pump. A failing FSCM is often misdiagnosed as a bad fuel pump.
Will this fix a P069E code?
Yes, in the vast majority of cases, a faulty FSCM is the root cause of a P069E diagnostic trouble code. Replacing it with this pre-programmed unit is the standard, reliable repair for that issue.
