Is Your GM Truck or SUV Stalling or Refusing to Start?
There’s nothing more frustrating than a vehicle that leaves you stranded. If your Silverado, Sierra, Tahoe, Escalade, or other GM vehicle is suddenly stalling, cranking but not starting, or displaying a “Service Fuel System” message, the culprit is often a failed Fuel System Control Module (FSCM). As a mechanic with over 20 years of experience, I’ve seen this exact scenario hundreds of times. The check engine light comes on, and a scan tool reveals codes like P069E, P0230, or U0109, all pointing directly to a communication or performance issue with this critical component.
The FSCM acts as the brain for your fuel pump, regulating the voltage and pressure to ensure your engine gets the precise amount of fuel it needs. When it fails, the fuel pump can stop working intermittently or altogether, leading to the exact symptoms you’re experiencing. Don’t replace the entire fuel pump assembly until you’ve checked this moduleโit’s a common misdiagnosis that costs people a lot of unnecessary money.

Expert Pro Tip from a 20-Year Veteran Mechanic
Before installing your new FSCM, take a close look at the vehicle’s wiring harness connector. These modules are often mounted on the frame rail, exposed to road salt, water, and grime. I’ve seen countless modules replaced when the real issue was a corroded pin inside the connector. Use a small brush and electrical contact cleaner to thoroughly clean the harness plug. A clean, secure connection is critical for the new module to function correctly and will prevent future issues.
Simple Plug-and-Play Installation Guide
You can get your vehicle back on the road in under an hour with basic hand tools. The module is typically located on the driver-side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Old Module: Find the FSCM on the frame rail or crossmember. It’s a small black box with a single large electrical connector.
- Disconnect and Remove: Carefully unplug the wiring harness. Then, unbolt the module from its mounting bracket. There are usually two or three bolts holding it in place.
- Install the New Module: Bolt your new, pre-programmed module into the same location. Reconnect the wiring harness, ensuring it clicks securely into place.
- Final Steps: Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming needed.
