Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
As a mechanic with over two decades of experience, one of the most common issues I see on 2010-2012 GM vehicles is a sudden loss of power, erratic engine behavior, or a complete no-start condition. Often, the culprit isn’t the fuel pump itself, but the small black box that controls it: the Fuel System Control Module (FSCM). This module, often mounted on the frame rail, is exposed to road salt, water, and vibration, leading to internal failure and leaving you stranded. A tell-tale sign is often the diagnostic trouble code (DTC) P069E stored in the computer.
The Plug-and-Play Solution: A Module Programmed Specifically for YOU
Don’t waste time and money at the dealership. This isn’t just a replacement part; it’s a complete solution. We take a genuine OEM-quality Fuel System Control Module and professionally flash it with the latest GM software, calibrated precisely to your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures seamless communication with your vehicle’s other computers, restoring factory performance and reliability right out of the box.
Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Stalling while driving, especially under load
- โ Rough idle or engine hesitation
- โ Reduced engine power and poor acceleration
- โ Check Engine Light with code P069E
Expert Pro Tip from a 20-Year Veteran Technician
Before you install your new module, take a close look at the vehicle’s wiring harness connector. Because these modules are often mounted on the frame, I’ve seen countless repairs fail prematurely due to corrosion on the connector pins. Use a small wire brush and a quality electronic contact cleaner to thoroughly clean both the pins and the inside of the harness plug. A clean connection is just as important as a new part for a lasting repair.
Why is VIN Programming Essential for a GM Fuel Control Module?
In modern GM vehicles, the GM Fuel Control Module is a networked computer. It doesn’t just send power to the fuel pump; it receives precise commands from the Engine Control Module (ECM) to vary fuel pressure based on engine load, speed, and other factors. A generic, non-programmed module from a parts store or salvage yard won’t have the correct software for your specific vehicle’s configuration (engine, transmission, emissions). This mismatch can lead to persistent performance issues, new trouble codes, or the module simply not working at all. Our VIN-programming service eliminates this guesswork and guarantees compatibility.
Simple Plug-and-Play Installation: No Dealer Visit Required
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Old Module: On most trucks and SUVs (Silverado, Sierra, Tahoe, Yukon, Escalade), the FSCM is mounted on the driver’s side frame rail, near the spare tire. On other models (CTS, LaCrosse, Acadia), it may be in the trunk or rear compartment area.
- Disconnect and Remove: Carefully unplug the electrical connector. Then, remove the bolts or nuts securing the old module to the frame or chassis.
- Install the New Module: Mount your new, pre-programmed module in the same location. Secure it with the original hardware.
- Reconnect: Plug the wiring harness connector firmly into the new module. You should hear a click.
- Final Step: Reconnect the negative battery terminal. Start the vehicle and verify that the engine runs smoothly and the Check Engine Light is off.
