Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
You turn the key, and instead of a confident roar, you get a weak crank, a sputter, or nothing at all. Maybe your vehicle starts but then stalls unexpectedly at a stoplight, leaving you stranded. If you’re seeing a check engine light with code P069E, or experiencing erratic fuel gauge behavior alongside these symptoms, the culprit is very likely a failing Fuel System Control Module (FSCM).
Over my 20 years on the shop floor, I’ve seen this exact scenario play out hundreds of times on otherwise reliable Chevy Silverados, GMC Sierras, Tahoes, and Escalades from this era. The original FSCM, often mounted on the frame rail, is vulnerable to moisture and corrosion, leading to internal failure that disrupts the signal to your fuel pump.
A Real-World Diagnosis Story: “Just last month, a 2011 GMC Sierra 1500 was towed in. The owner had already replaced the fuel pump, thinking that was the issue, but the truck still wouldn’t run for more than a few seconds. A quick scan showed the classic P069E code. We inspected the FSCM connectorโit was green with corrosion. After cleaning the harness plug and installing one of our pre-programmed modules, the truck fired right up and ran perfectly. He could have saved himself hundreds of dollars and a lot of frustration by starting with the FSCM.”

Easy Installation Guide: Get Back on the Road Fast
While the exact location can vary slightly, on most trucks and SUVs like the Silverado, Tahoe, and Yukon, you’ll find the module on the driver’s side frame rail, near the spare tire. The job can typically be done in under 30 minutes with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the FSCM: Find the old module. It’s a small, black box with an electrical connector, usually held on by two or three bolts.
- Disconnect and Remove: Carefully unplug the electrical connector. Use a small screwdriver to release the locking tab if necessary. Then, unbolt and remove the old module.
- Install the New Module: Bolt your new, pre-programmed GM Fuel Control Module into place.
- Connect and Secure: Firmly plug in the electrical connector until it clicks. Give it a gentle tug to ensure it’s secure.
- Final Step: 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. Start your vehicle and enjoy a smooth-running engine!
