Is Your GM Truck or SUV Stalling or Losing Power?
There’s nothing more frustrating than your reliable Silverado, Tahoe, or Escalade suddenly hesitating, stalling out, or flashing a ‘Reduced Engine Power’ message. You hit the gas, and it feels like the engine is starving for fuel. Often, the blame is immediately placed on the in-tank fuel pump, a costly and labor-intensive repair. But after 20+ years under the hood, I can tell you that a huge percentage of the time, the real culprit is a much simpler, more accessible part: the Fuel System Control Module (FSCM).
From the Shop Floor: A Real-World Scenario
A customer’s 2011 Sierra 1500 came in last week with these exact symptoms. It would crank but not start, and when it did run, it had no power. The owner had already replaced the fuel pump himself, but the problem persisted. A quick scan showed code P069E – ‘Fuel Pump Control Module Commanded OFF’. Instead of another expensive pump, we checked the FSCM mounted on the driver-side frame rail. It was corroded from years of exposure to road salt and moisture. We installed one of our pre-programmed modules, and the truck fired right up and ran perfectly. He could have saved hundreds of dollars and a full weekend of work by diagnosing the FSCM first.
The Smart Solution: A VIN-Programmed Module Ready to Install
This isn’t just a replacement part; it’s a complete solution. We take a genuine GM Fuel System Control Module and program it specifically to your vehicle’s Vehicle Identification Number (VIN) before we ship it. This means it arrives at your door loaded with the latest GM software updates, ready for a true plug-and-play installation. You get to skip the expensive trip to the dealership for programming, saving you time and money.
Diagnosing a Failing GM Fuel Pump Module
If you’re experiencing any of the following issues, a faulty FSCM is a highly likely cause. These modules are notorious for failing due to their exposed mounting location on many trucks and SUVs, leading to water intrusion and corrosion.
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or acceleration
- ✔ ‘Reduced Engine Power’ message on the dash
- ✔ Hesitation or sputtering during acceleration
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
Plug-and-Play Installation: No Dealer Visit Required
Replacing the FSCM is a straightforward job that most DIY mechanics can handle in their own driveway. Because we program it for you, no special tools or dealer software is needed.
- Safety First: Disconnect the negative battery terminal.
- Locate the Module: On most trucks and SUVs (like the Silverado, Tahoe, Yukon, and Avalanche), you’ll find the FSCM mounted to the driver-side frame rail, near the spare tire. On cars like the CTS or LaCrosse, it’s typically in the trunk or rear compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small screwdriver to release the locking tabs if necessary. Then, unbolt the module from its bracket.
- Install the New Module: Bolt the new, pre-programmed module in place. Reconnect the electrical connectors, ensuring they click securely.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for a few seconds to prime the system, then start the vehicle. Your fuel delivery issues should be resolved.
