Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re dealing with frustrating fuel delivery problems like engine stalling, a ‘Reduced Engine Power’ message, or a complete no-start condition, a faulty Fuel System Control Module (FSCM) is a very common culprit. Located on the frame rail of most GM trucks and SUVs, this critical component is constantly exposed to road salt, water, and vibration, which often leads to internal failure or corroded connections, triggering diagnostic trouble codes like P069E, P0230, or U0109.
From the Shop Floor: A Real-World Diagnosis
“A customer’s 2011 Silverado 1500 came in last week on a tow truck. It would crank but wouldn’t start, and the fuel pump wasn’t priming. The scan tool showed a P069E code, indicating a fault in the FSCM control circuit. A quick visual inspection under the truck confirmed my suspicion: the module’s aluminum casing was heavily pitted, and the main connector was green with corrosion. After replacing the FSCM with one of our pre-programmed units and cleaning the connector pins, the truck fired right up. This is a repair I’ve done hundreds of times; exposure is the number one killer of these modules.”

Plug-and-Play Installation Guide (Typical Truck/SUV):
Installing your new GM Fuel Control Module is straightforward. While locations vary slightly, the process is generally the same for most trucks and SUVs where it’s mounted on the frame.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM, typically mounted on the driver’s side frame rail, often near the spare tire.
- Disconnect Connectors: Carefully press the release tabs and unplug the electrical connectors. Inspect the harness-side connectors for any corrosion and clean them with a contact cleaner if necessary.
- Remove Old Module: Unbolt the two fasteners holding the module to its bracket or the frame.
- Install New Module: Mount your new, pre-programmed module, reconnect the electrical connectors until they click, and re-attach the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the system to prime, then start the engine. Your issue should be resolved.
