Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
You turn the key, the engine cranks, but it just won’t fire up. Or maybe it starts, but sputters and dies, leaving you stranded. These are classic, frustrating symptoms of a failing Fuel System Control Module (FSCM), a critical component in many 2010-2012 GM vehicles. As a mechanic with over two decades of experience, I’ve seen this exact scenario play out hundreds of times. The original FSCM, often mounted on the frame rail, is vulnerable to moisture and corrosion, leading to erratic fuel pressure and a host of drivability nightmares.

Forget about expensive towing bills and dealership programming fees. This is a direct-fit Programmed Fuel Control Module that arrives at your doorstep ready for installation. We take the hassle out of the repair by flashing the module with the latest GM software updates, specifically matched to your vehicle’s VIN. You’re not just getting a part; you’re getting a complete, personalized solution that restores factory performance and reliability.
Expert Pro Tip: Check for Corrosion Before You Install
Before you bolt on your new FSCM, take a minute to inspect the electrical connector and the mounting location on the frame. I’ve seen countless repeat failures caused by a corroded connector harness. Use a small wire brush and electrical contact cleaner to scrub away any green or white powder from the pins and the vehicle’s harness plug. A clean connection is crucial for the new module to function correctly and last for years to come. This simple step can save you from a major headache down the road.

- Safety First: Disconnect the negative terminal from your vehicle’s battery.

- Disconnect and Remove: Carefully unplug the electrical connector. Then, remove the bolts holding the old module to the frame.
- Install the New Module: Bolt your new, pre-programmed FSCM into place. Firmly reconnect the electrical harness until it clicks.
