Restore Your Truck’s Performance and Reliability
If your 2010-2012 Chevrolet Avalanche is experiencing frustrating issues like stalling, hesitation, a no-start condition, or a persistent Check Engine Light, a failing Fuel System Control Module (FSCM) is a very common culprit. This module, often called the fuel pump driver module, is the brain that precisely controls the fuel pump’s voltage and speed. When it fails, it starves your engine of the fuel it needs, leading to poor performance and leaving you stranded. This isn’t just an inconvenience; it’s a critical component for your vehicle’s operation.
We solve this problem by providing a direct-replacement FSCM that arrives at your door pre-programmed and ready for installation. Simply provide your vehicle’s VIN at checkout, and our technicians will flash the module with the latest, most stable GM software specific to your truck. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money. With our 2010-2012 Avalanche FSCM, you get a reliable, plug-and-play solution to get your truck running right again.
Case Study: The “Bad” Fuel Pump That Wasn’t
A customer brought in his 2011 Sierra with a classic no-start complaint. He had already spent a considerable amount of money replacing the in-tank fuel pump himself, but the truck still wouldn’t fire up. He was frustrated, to say the least. After a quick check, we found no power going to the new pump. Instead of working backward from the pump, we went straight to the common point of failure on these GM trucks: the FSCM mounted on the frame rail. It was heavily corroded from years of exposure to road salt and moisture. We installed a new, programmed FSCM, and the truck started instantly. This is a story I’ve seen play out dozens of times; diagnosing the FSCM first can save you from a costly and unnecessary fuel pump replacement.
Is Your GM Truck or SUV Showing These Signs?
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when warm
- ✔ Rough idle or engine hesitation
- ✔ “Reduced Engine Power” message on the dash
- ✔ Check Engine Light with codes like P069E, P0230, P2635, or U0109
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery.
- ✔ Locate the Module: On most GM trucks like the Avalanche, the FSCM is mounted on the driver’s side frame rail, typically above the spare tire.
- ✔ Disconnect Wiring: Carefully unplug the electrical connectors from the old module. Press the release tabs firmly to avoid breaking them.
- ✔ Remove Old Module: Unbolt the old FSCM from the frame. These bolts can sometimes be rusty, so a little penetrating oil might be helpful.
- ✔ Install New Module: Bolt the new, pre-programmed FSCM into place and securely reconnect the electrical harnesses.
- ✔ Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming required.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN (Vehicle Identification Number) allows us to program the module with the exact software and calibrations your vehicle’s specific configuration requires. This ensures perfect communication with your engine computer (ECM) and guarantees a plug-and-play installation without needing a dealer visit.
Where is this module located on my 2011 Avalanche?
On the 2010-2012 Avalanche and similar GM trucks, the Fuel System Control Module is typically mounted to the outside of the driver’s side frame rail, often near or above the spare tire. It’s exposed to the elements, which is a primary reason for its failure.
Is this part difficult to install for a DIYer?
No, this is a very DIY-friendly repair. Since the module comes pre-programmed, the job only requires basic hand tools to unbolt the old unit and install the new one. The most common challenge is dealing with potentially rusty bolts.
Will this fix a P069E trouble code?
Yes, the diagnostic trouble code P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common indicators of a failed FSCM. Replacing the module is the standard and effective repair for this code.
What’s the difference between this and a part from a salvage yard?
A used module from a salvage yard will be programmed for the vehicle it came from, not yours. It would still require a trip to a dealer or equipped shop for proper programming. Furthermore, being a used part, it carries the same risk of failure from age and corrosion. Our module is tested, loaded with fresh software for your VIN, and ready to provide reliable service.
