Is Your GM Truck or SUV Stalling or Losing Power?
If you’re dealing with frustrating issues like your engine cranking but not starting, sudden stalling, a check engine light with fuel system codes (like P069E or P0230), or a “Service Fuel System” message, the culprit is often a failed Fuel System Control Module (FSCM). Located on the frame rail of most GM trucks and SUVs, this critical component is exposed to harsh road conditions, leading to corrosion and internal failure. Don’t let a small module sideline your entire vehicle.
The Plug-and-Play Solution: A Pre-Programmed GM Fuel Control Module
Replacing the FSCM used to mean a trip to the dealership for expensive diagnostics and programming. We eliminate that hassle. This is a genuine GM Fuel System Control Module that we program specifically to your vehicle’s VIN before it ships. It arrives at your door loaded with the latest GM software, ready for a straightforward installation. You get a reliable repair that restores factory performance without the dealer price tag.
From the Shop Floor: A Real-World Diagnosis
“A customer’s 2011 Silverado 1500 came in last week with a classic no-start after a heavy rainstorm. It would crank all day but never fire. The owner had already replaced the fuel pump, but the problem persisted. We put it on the lift and immediately saw the issue. The FSCM, mounted to the frame, had its main connector packed with greenish-white corrosion. The constant exposure to water and road salt had compromised the pins, causing an intermittent loss of communication with the fuel pump. We installed one of our pre-programmed modules, applied dielectric grease to the new connector, and the truck fired up on the first try. It’s a repair I’ve done hundreds of times on these GM platforms.”

Simple Installation Guide
Installing your new GM Fuel Control Module is a job most DIYers can handle in under an hour. While the exact location varies slightly by model (e.g., frame rail on a Sierra, rear compartment on a CTS), the process is similar.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Old Module: On most trucks and large SUVs, find the FSCM mounted to the driver’s side frame rail, often near the spare tire. On cars, it may be in the trunk or rear compartment.
- Disconnect and Remove: Carefully unplug the electrical connector. Inspect the harness side for any corrosion and clean it if necessary. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed FSCM into place. Apply a small amount of dielectric grease to the connector pins to prevent future moisture intrusion.
- Connect and Finalize: Securely plug in the electrical connector until it clicks. Reconnect the negative battery terminal.
- Start the Vehicle: Your vehicle should now start and run correctly with proper fuel pressure. Clear any stored diagnostic trouble codes with a scan tool.
Important: After purchasing, please send us your 17-digit VIN. We cannot ship your order until we have programmed the module. This step is critical to ensure a successful, hassle-free repair.
