Is Your GM Truck or SUV Stalling, Cranking but Not Starting, or Throwing a P069E Code?
If you’re experiencing erratic fuel gauge readings, a sudden loss of power, or your vehicle simply refuses to start, a failing Fuel System Control Module (FSCM) is the most likely culprit. In my 20+ years as a diagnostic technician, I’ve seen hundreds of 2010-2012 GM vehicles come into the shop with these exact symptoms. A customer’s 2011 Silverado 1500 came in last week on a tow truck; it would crank all day but never fire up. He had already replaced the fuel pump, wasting over $400, but the problem persisted. The real issue, confirmed by a quick scan, was a dead FSCM showing code U0109 (Lost Communication With Fuel Pump Control Module). This is a story I’ve seen play out time and time again.
Don’t just throw parts at the problem. This is the correct, permanent fix. This Fuel System Control Module is the central command for your vehicle’s fuel delivery. It precisely regulates the voltage sent to the fuel pump, ensuring optimal fuel pressure under all driving conditions. When it fails, it leaves you stranded.
The Plug-and-Play Solution: A Pre-Programmed GM Fuel Pump Module
The biggest headache with replacing modern vehicle electronics is the required programming. A new module from the dealer is just a blank box; it requires an expensive trip to their service department for programming with their proprietary tools. Our solution eliminates that step entirely. We take a genuine GM module and flash it with the latest, most stable software directly from GM, programmed specifically to your vehicle’s 17-digit VIN. When it arrives at your door, it’s ready for a simple, direct installation.
Expert Pro Tip: Prevent a Repeat Failure
These modules are often mounted on the frame rail, exposed to road salt and moisture. This is the #1 cause of failure I see in the shop. Before installing your new module, take a moment to clean the vehicle’s harness connectors with a dedicated contact cleaner. A dab of dielectric grease on the connector seal can prevent future moisture intrusion and a repeat failure down the road.

Plug-and-Play Installation: No Dealer Visit Required
You can do this repair in your own driveway with basic hand tools. Hereโs a general guide for most trucks and SUVs like the Silverado, Sierra, and Tahoe:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the FSCM: On most trucks, you’ll find it mounted to the inside of the driver-side frame rail, near the spare tire. On other models like the Cadillac CTS or Buick Enclave, it may be in the trunk or on a rear crossmember.
- Disconnect and Remove: Carefully unplug the two electrical connectors. Then, remove the bolts holding the old module to the frame.
- Install the New Module: Bolt your new, pre-programmed FSCM into place and securely plug in the electrical connectors. You should hear a click.
- Reconnect Power: Re-attach the negative battery terminal.
- Final Step: Cycle the key to the ‘ON’ position (without starting) for 10 seconds, then ‘OFF’ for 10 seconds. Do this twice before starting the engine. This allows the vehicle’s main computer to recognize the new module.
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 for your specific vehicle.
