Restore Your Tahoe’s Power and Reliability
Is your 2010-2012 Chevrolet Tahoe stalling, hesitating, or refusing to start? A faulty Fuel System Control Module (FSCM) is one of the most common culprits behind these frustrating and potentially dangerous issues. This critical component, also known as a fuel pump driver module, regulates the voltage sent to the fuel pump. When it fails, it starves your engine of the fuel it needs, leading to poor performance, a check engine light, and eventually, a vehicle that won’t run at all. Don’t get stranded or waste money on the wrong diagnosis. This is the direct, reliable solution you need.
We solve the biggest headache of replacing modern electronics: programming. This FSCM arrives at your door fully programmed to your specific vehicle. Simply provide us with your Tahoe’s Vehicle Identification Number (VIN) after purchase, and our technicians will flash the module with the latest GM software updates. This means no expensive trips to the dealership, no special scan tools required—just a straightforward installation to get you back on the road with confidence. This is the ideal fix for both seasoned mechanics and first-time DIYers.
A Technician’s Notebook
I had a 2011 Silverado in the bay last month with a classic ‘crank, no start’ condition. The owner had already replaced the in-tank fuel pump himself, but the truck still wouldn’t fire up. He was frustrated and out a few hundred dollars. After hooking up my scanner, I saw code U0109 – ‘Lost Communication With Fuel Pump Control Module’. Instead of checking pressure at the rail, I went straight to the FSCM on the driver-side frame rail. It was covered in road grime and corrosion. A quick voltage check confirmed it was dead. We installed one of our pre-programmed modules, and the truck started on the first try. It’s a textbook example of how diagnosing the 2010-2012 Tahoe FSCM correctly saves time and avoids replacing perfectly good parts.
Is Your Tahoe Showing These Warning Signs?
A failing FSCM can mimic other fuel system problems. Here are the most common indicators that your module needs attention:
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially under load
- ✔ Noticeable loss of engine power and poor acceleration
- ✔ Rough idling or engine sputtering
- ✔ Check Engine Light is on with specific trouble codes
- ✔ Common Diagnostic Trouble Codes (DTCs): P069E, P0230, U0109
Your Straightforward FSCM Installation Guide
Installing your pre-programmed 2010-2012 Tahoe FSCM is a manageable job for anyone with basic tools. On most GM trucks and SUVs, it’s located on the driver-side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FSCM mounted to the inside of the frame rail. It’s a small, black box with an electrical connector.
- Disconnect and Remove: Carefully unplug the electrical harness. Then, remove the bolts or nuts (typically two) holding the module to the frame. The old unit may be corroded, so some penetrating oil can help.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- Connect and Finalize: Plug the electrical connector firmly into the new module until it clicks. Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming needed.

Frequently Asked Questions
Does this FSCM really come ready to install?
Yes. This is a key benefit of our service. We use your VIN to program the module with the latest GM software before we ship it. It is a true plug-and-play solution, saving you a trip to the dealer.
How do I give you my VIN?
After you complete your purchase, please send us a message with your 17-digit VIN. We cannot program and ship your part without it. You can typically find your VIN on your driver-side door jamb sticker or dashboard plate.
Will this fix a P069E check engine light code?
In many cases, yes. Code P069E (Fuel Pump Control Module Requested MIL Illumination) is a very common indicator of a failing FSCM. While you should always perform a full diagnosis, a faulty module is the most frequent cause of this code.
Where is the FSCM located on my 2011 Tahoe?
On the 2010-2012 Tahoe, Suburban, and other GM trucks, the Fuel System Control Module is typically mounted to the driver’s side (LH) frame rail, often above or near the spare tire.
Is this the same as the in-tank fuel pump?
No. This is the electronic control module that tells the fuel pump how much voltage to use. The fuel pump is the mechanical part located inside your fuel tank. This module failing is often misdiagnosed as a bad fuel pump.
