Is Your GM Truck or SUV Stalling, Cranking but Not Starting?
You’re driving along, and suddenly the engine sputters and dies. Or maybe you go to start your truck in the morning, and it just cranks and cranks without firing up. If you’re seeing a “Service Fuel System” message on your dash, you’re likely dealing with a failed Fuel System Control Module (FSCM). Itโs a frustrating problem, but youโve found the right solution.
From the Shop Floor: A Real-World Scenario
“A customer’s 2011 Sierra 1500 was towed in last week with the classic no-start symptom. He’d already spent a fortune replacing the in-tank fuel pump, but the problem persisted. When I connected my scan tool, it immediately pulled code P069E – Fuel Pump Control Module Requested MIL Illumination. This code almost never points to the pump itself. The true culprit was the FSCM, which had corroded from its position on the frame rail. I’ve personally diagnosed this exact failure on hundreds of GM trucks; it’s one of the most common issues on this platform.”
The Direct Solution: A Programmed Fuel Control Module Ready for Installation
Forget expensive dealership visits and programming fees. This Fuel System Control Module is the definitive fix for your vehicle’s fuel delivery problems. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures it communicates perfectly with your vehicle’s computer systems right out of the box.
Key Symptoms This Part Resolves:
- โ Engine stalling, especially under load or when coming to a stop.
- โ Extended crank times or a complete no-start condition.
- โ Check Engine Light with common FSCM codes like P069E, P0230, or P0606.
- โ “Service Fuel System” warning message displayed on the instrument cluster.
- โ Inconsistent fuel pressure readings.
Plug-and-Play Installation: Get Back on the Road Fast
You don’t need to be a master technician to replace this module. With our pre-programmed unit, it’s a straightforward job you can do in your own driveway.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (Silverado, Sierra, Tahoe, Yukon), you’ll find the FSCM mounted to the driver’s side frame rail, near the spare tire. On cars and other SUVs (CTS, Acadia, Impala), it may be in the trunk or rear compartment area.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed FSCM into place and securely reconnect the electrical plugs.
- Final Step: Reconnect the battery terminal. Start the vehicle to confirm the repair is complete.
Expert Pro Tip: Connector Inspection is Crucial
Before you plug in your new module, take a bright light and carefully inspect the vehicle’s wiring harness connector. These modules often fail due to water and salt intrusion, and that corrosion can creep into the connector itself. If you see any green or white powder, use a small nylon brush and a quality electrical contact cleaner to thoroughly clean the pins. A clean, solid connection is vital for the longevity of your new part.
