Is Your GM Truck or SUV Stalling, Cranking with No Start, or in Limp Mode?
If you’re dealing with frustrating issues like your engine suddenly dying, a persistent “Reduced Engine Power” message, or a vehicle that cranks but refuses to start, the problem is very likely a failed Fuel System Control Module (FSCM). I’ve been a diagnostic technician for over 20 years, and on these 2010-2012 GM platforms, a faulty FSCM is one of the most common culprits I see for these exact symptoms, often throwing diagnostic trouble codes like P069E, P0230, or P0606.
Many owners mistakenly replace the in-tank fuel pump first, only to find the problem remains. The FSCM, often mounted to the frame rail, is exposed to water, salt, and vibration, which leads to internal corrosion and failure. This module is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to poor performance and no-start conditions.
Real-World Diagnosis: A Technician’s Experience
A customer’s 2011 Chevy Tahoe was towed into my shop last week with these exact symptoms. It would run for a few minutes and then stall, refusing to restart. The dash was lit up with a “Reduced Engine Power” warning. The owner was convinced he needed a new fuel pump. However, a quick scan with a professional tool revealed code P069E – Fuel Pump Control Module Commanded OFF. A visual inspection confirmed my suspicion: the original FSCM on the driver-side frame rail was heavily corroded. We replaced it with one of our pre-programmed modules, and the Tahoe fired right up and ran perfectly. He saved hundreds by not replacing a perfectly good fuel pump.

Simple Installation Guide: Get Back on the Road Fast
Installing your new FSCM is straightforward. For most trucks and SUVs like the Silverado, Sierra, Tahoe, and Yukon, the module is located on the driver-side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FSCM. It’s a small black box with electrical connectors, typically held on by two or three bolts.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small screwdriver to release the locking tabs if necessary. Then, unbolt and remove the old module.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the electrical connectors, ensuring they click securely.
- Final Step: Reconnect the negative battery terminal. Start the vehicle and verify that the warning lights are off and the engine runs smoothly.
