Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re dealing with frustrating fuel delivery problems in your 2010-2012 GM vehicle, a faulty Fuel System Control Module (FSCM) is a very common culprit. You might be seeing a check engine light with codes like P069E, P0230, or P0606, or experiencing symptoms like a long crank time, sudden engine stalling, or inconsistent power. Don’t replace the fuel pump until you’ve checked this moduleโit could save you hundreds of dollars.
A Real-World Scenario from My Shop
Just last month, a 2011 Silverado 1500 was towed in with a classic no-start condition. The owner had already replaced the fuel pump himself, but the truck still wouldn’t fire up. A quick scan showed a P069E code: Fuel Pump Control Module Requested MIL Illumination. I went straight to the FSCM, mounted on the driver-side frame rail. As I suspected, years of exposure to road salt and moisture had corroded the module’s casing and compromised the internal electronics. We installed one of our pre-programmed modules, and the truck started on the first try. Itโs a textbook failure I’ve seen hundreds of times on these GM platforms.

Expert Pro Tip: Prevent Future Corrosion
The original FSCMs on many trucks and SUVs are notorious for failing due to their mounting location on the frame. Before installing your new module, take a wire brush and thoroughly clean any rust or debris from the mounting point on the frame. A clean, metal-to-metal contact is crucial. For extra protection in harsh climates, apply a thin layer of dielectric grease to the back metal plate of the new module before bolting it on. This creates a barrier against moisture and can significantly extend its life. Do NOT apply grease inside the electrical connector pins.
Plug-and-Play Installation: No Dealer Visit Required
You can get your vehicle back on the road in under an hour with basic hand tools. While the exact location varies by model (check your service manual), the process is straightforward.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the FSCM: On most trucks/SUVs (Silverado, Tahoe, Escalade), it’s on the driver-side frame rail, often near the spare tire. On cars/crossovers (CTS, Acadia, LaCrosse), it may be in the trunk or on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical harness connector. Then, unbolt the old module from its mounting location.
- Install the New Module: Bolt your new, pre-programmed module securely in place.
- Reconnect: Plug the electrical connector firmly into the new FSCM until it clicks. Reconnect the negative battery terminal.
- Prime the System: Turn the key to the ‘On’ position (without starting) for 5-10 seconds, then turn it off. Repeat this 2-3 times to allow the fuel pump to prime the system before starting the engine.
