Restore Your Escalade’s Performance and Reliability
Is your 2010-2012 Cadillac Escalade EXT experiencing frustrating issues like stalling, sputtering, or a dreaded no-start condition? A faulty Fuel System Control Module (FSCM) is often the culprit. This critical component regulates the voltage sent to your fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded and facing a costly dealership visit. This module is your direct-fit, plug-and-play solution, arriving pre-programmed to your vehicle’s specific VIN. Forget about expensive towing and programming fees; this is the efficient fix that gets you back on the road with confidence.
From the Diagnostic Bay: The Misdiagnosed Fuel Pump
A customer brought in his 2011 Sierra, convinced he needed a new fuel pump. The truck would crank but not start, and when it did run, it had no power. He’d already spent a weekend preparing to drop the fuel tank. I told him to hold off. I hooked up my scan tool and saw DTC P069E, a classic code pointing to the FSCM. These modules, especially on trucks exposed to the elements, are notorious for corrosion and internal failure. We swapped in a new FSCM in under 30 minutes, right on the frame rail. The truck fired right up. He saved himself a full day of unnecessary labor and the cost of a fuel pump he didn’t need. Always check the FSCM first!
Common Signs of a Failing Fuel System Control Module
If you’re noticing any of these issues, a failing FSCM is a likely cause. Replacing it can restore your vehicle’s performance and prevent further engine trouble.
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ “Reduced Engine Power” message on the dash
- ✔ Hesitation or sputtering during acceleration
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ Inconsistent fuel pressure readings
Your Straightforward FSCM Installation Guide
Installing your new 2010-2012 Escalade EXT FSCM is a simple process that most DIYers can complete with basic hand tools. This module is typically located on the driver-side frame rail, making it easily accessible.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the inside of the driver-side frame rail, often near the spare tire.
- Disconnect: Carefully unplug the electrical connectors from the old module. Press the release tabs firmly to avoid damaging the clips.
- Remove Old Module: Unbolt the old FSCM from the frame. It’s typically held on by two or three small bolts.
- Install New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original bolts.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they lock into place.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds before starting the engine to allow the system to prime.

Why do you need my VIN?
Your Vehicle Identification Number (VIN) is required so we can program the module with the latest GM software specific to your Escalade EXT’s configuration. This ensures perfect communication with your vehicle’s other computers and guarantees a simple, plug-and-play installation without needing a trip to the dealer.
Is this part difficult to install?
Not at all. For most trucks and SUVs like the Escalade, the FSCM is mounted on the frame rail and is accessible with basic hand tools. Our installation guide above walks you through the process, which typically takes less than an hour for a DIY mechanic.
Will this fix a P069E check engine code?
Yes, a faulty FSCM is the most common cause of a P069E trouble code (Fuel Pump Control Module Requested MIL Illumination). Replacing the module with this pre-programmed unit is the correct and reliable fix for this issue.
How is this different from a part from the auto parts store?
Standard off-the-shelf modules are not programmed. You would have to install it, then have your vehicle towed to a dealership or a shop with expensive GM programming tools to have it flashed. Our service handles the programming for you, saving you significant time, money, and hassle.
My truck hesitates but doesn’t stall. Could this still be the FSCM?
Absolutely. An intermittent or failing FSCM can cause a wide range of fuel delivery problems, including hesitation, poor acceleration, and rough idling, long before it fails completely. It’s a key part of the fuel system that can cause many drivability issues.
