Is Your GM Truck or SUV Stalling or Refusing to Start?
You turn the key, and… nothing. Or maybe your 2011 Silverado sputters and dies at a stoplight, leaving you stranded. As a technician with over 20 years in the bay, I’ve seen this scenario play out hundreds of times. The dashboard might show a ‘Reduced Engine Power’ message, and a scan tool often reveals the dreaded P069E, P0230, or U0109 trouble codes. Many people immediately suspect the fuel pump, but very often, the real culprit is a failed Fuel System Control Module (FSCM).
A customer’s 2011 GMC Yukon came in last week with these exact symptoms. It would crank but not start, and when it did run, it was rough. The owner had already replaced the fuel pump, but the problem persisted. We hooked up our diagnostic tools and saw the voltage to the fuel pump was erratic. The problem wasn’t the pump; it was the brain telling it what to do. A new, properly programmed FSCM had his Yukon running smoothly in under an hour. This is a common and frustrating misdiagnosis that you can avoid.
The Plug-and-Play Solution: A Pre-Programmed FSCM
This isn’t just a replacement part; it’s a complete solution. This Fuel System Control Module, also known as a Fuel Pump Driver Module, is the definitive fix for a wide range of 2010-2012 GM vehicles. The biggest hurdle with replacing these modules has always been the mandatory, and often expensive, trip to the dealership for programming. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our certified technicians will flash the module with the latest, most stable GM software specific to your vehicle. It arrives at your door ready for a straightforward installation.

Expert Pro Tip: On trucks and SUVs like the Tahoe, Sierra, and Escalade, these modules are often mounted on the driver-side frame rail, where they’re exposed to road salt and moisture. Before installing your new module, take a minute to clean the mounting area and the electrical connector with a wire brush and contact cleaner. Applying a thin layer of dielectric grease to the connector pins is a simple step that prevents future corrosion and ensures a solid, long-lasting connection.
Simple, DIY-Friendly Installation
You don’t need to be a master mechanic to replace this part. With basic hand tools, you can get your vehicle back on the road quickly. While the exact location varies by model (check your service manual), the process is generally straightforward.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FSCM. On most trucks/SUVs (Silverado, Tahoe, Yukon), it’s on the driver’s side frame rail near the spare tire. On cars (CTS, LaCrosse), it may be in the trunk or rear compartment.
- Disconnect and Remove: Unplug the electrical connector and unbolt the module from its mounting point.
- Install the New Module: Bolt the new, pre-programmed module into place and securely plug in the connector.
- Reconnect and Start: Reconnect the battery terminal. Your vehicle should now start and run correctly with no warning lights.
Don’t let a faulty module dictate your schedule. Take control of your repair with a reliable, pre-programmed FSCM and restore your vehicle’s dependability today.
