Restore Your Truck’s Performance and Reliability
Is your 2010-2012 Chevrolet Avalanche stalling, hesitating, or refusing to start? 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 countless GM trucks and SUVs sidelined by a faulty FSCM. This module is the brain of your fuel delivery system, controlling the voltage sent to the fuel pump. When it fails, it can cause intermittent fuel pressure, leading to a host of frustrating and potentially dangerous engine problems.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair by pre-programming this module to your vehicle’s specific VIN with the latest GM software updates. This means you can skip the costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll ship a module that’s truly plug-and-play, getting your truck back on the road quickly and reliably. This is the definitive fix for a failing 2010-2012 Avalanche FSCM.
A Technician’s Notebook: The Misleading P069E Code
A customer brought in his 2011 Sierra 1500 with a persistent ‘Engine Power Reduced’ message and a P069E trouble code. He had already replaced the in-tank fuel pump himself, but the problem remained. On these GM platforms, the P069E code points to a performance issue in the fuel pump control circuit. While it can indicate a bad pump, it’s very often caused by the FSCM itself failing to provide the correct voltage. The module is mounted on the frame rail, exposed to water, salt, and road debris, leading to corrosion and internal failure. After a quick 15-minute swap with a programmed FSCM, the code was cleared and the truck ran perfectly. It’s a classic case where diagnosing the controller, not just the component it controls, saves time and money.
Is Your Avalanche Exhibiting These Symptoms?
- âś” Engine cranks but will not start
- âś” Stalling, especially under load or when coming to a stop
- âś” ‘Engine Power Reduced’ message on the dash
- âś” Intermittent hesitation or stumbling during acceleration
- âś” Check Engine Light with codes like P069E, U0109, or P0230
- âś” A noticeable whine from the fuel pump that changes pitch erratically
A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- âś” Locate the Module: On most GM trucks and SUVs like the Avalanche, the FSCM is mounted on the driver’s side frame rail, typically near the spare tire.
- âś” Disconnect and Remove: Unplug the electrical connectors. Be gentle with the locking tabs. Then, remove the bolts or nuts securing the old module to the frame.
- âś” Install the New Module: Mount your new, pre-programmed 2010-2012 Avalanche FSCM in the same location and secure it with the original hardware.
- âś” Reconnect: Firmly plug in the electrical connectors until they click into place. Double-check that they are secure.
- âś” Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair is successful. The engine should start and run smoothly.
By investing in this pre-programmed 2010-2012 Avalanche FSCM, you are not just buying a part; you are buying peace of mind. You’re getting a reliable component with the newest software that directly addresses common failure points, ensuring your vehicle’s fuel system operates exactly as the manufacturer intended.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the biggest benefit of our service. We program the module to your vehicle’s VIN before shipping it. It arrives ready for a simple, plug-and-play installation, saving you hundreds in dealership fees.
Where is the FSCM located on a 2010 Avalanche?
You will find the Fuel System Control Module mounted to the inside of the driver’s side frame rail, typically located above the spare tire area. Its exposure in this location is a common reason for its failure due to moisture and debris.
Is this the same as the fuel pump?
No. The fuel pump is located inside your fuel tank. This Fuel System Control Module (FSCM) is the separate computer that controls the fuel pump’s operation. Many people mistakenly replace the pump when this module is the actual point of failure.
Will this fix a P069E check engine light code?
Yes, in a vast majority of cases. The DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is the most common code associated with a failing FSCM on these GM vehicles. Replacing the module with this pre-programmed unit is the standard, effective repair.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We use this to load the correct, updated GM software for your specific vehicle configuration.
