Is Your GM Truck or SUV Stalling or Refusing to Start?
If you’re dealing with frustrating issues like your engine cranking but not starting, sudden stalling while driving, or a persistent Check Engine Light with code P069E, a failing Fuel System Control Module (FSCM) is the most likely culprit. In my 20+ years as a technician, I’ve seen this exact scenario hundreds of times, especially on GM vehicles from the 2010-2012 era. The original modules, often mounted on the frame rail, are highly susceptible to moisture and road salt, leading to internal corrosion and failure.
A Technician’s Real-World Experience
“Just last month, a 2011 Silverado 1500 was towed into my bay. The owner had already replaced the fuel pump, thinking that was the issue, but the truck still wouldn’t start. A quick scan showed code P069E, pointing directly to the FSCM. We found the original module on the driver-side frame rail, its casing swollen and the connector pins green with corrosion. Replacing the module fixed the problem instantly. This isn’t a rare case; it’s a pattern I’ve diagnosed and fixed on countless Tahoes, Yukons, and Sierras.”

Plug-and-Play Installation: No Dealer Visit Required
You can perform this repair right in your own driveway. The location of the module varies by model (check your service manual), but is commonly found on the driver’s side frame rail on trucks/SUVs or inside the trunk/rear compartment on cars.
- Safety First: Disconnect the negative battery terminal.
- Locate the Old Module: Find the existing FSCM. It’s a small black box with an electrical connector.
- Disconnect and Remove: Carefully unplug the wiring harness and unbolt the old module from its mounting location.
- Inspect the Connector: Before plugging in your new module, carefully inspect the vehicle’s wiring harness connector for any signs of corrosion (green or white powder). Clean it thoroughly with a contact cleaner and a small brush if needed.
- Install the New Module: Bolt the new, pre-programmed module into place and securely plug in the wiring harness.
- Reconnect and Start: Reconnect the battery terminal. The vehicle may take a few extra seconds to crank on the first start as the fuel system re-pressurizes. Your Check Engine Light should be off and the problem resolved.
IMPORTANT: After you complete your purchase, please send us a message with your 17-digit VIN. We cannot ship your order until we have programmed the module. This step is critical to ensure it works perfectly with your vehicle.
