Is Your Truck or SUV Stalling, Hesitating, or Showing a Check Engine Light?
There’s nothing more frustrating than a vehicle you can’t depend on. If your GM truck, like a Sierra Denali or Silverado, is experiencing sudden power loss, a rough idle, or a no-start condition, a failing Fuel System Control Module (FSCM) is a very likely culprit. This critical component regulates the voltage sent to your fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it leaves you with an unreliable and potentially unsafe vehicle. You’ve found the definitive solution to get your truck back to peak performance and reliability.

An Expert’s Diagnostic Tip
“I’ve seen countless technicians and DIYers waste hundreds of dollars replacing a perfectly good fuel pump, only to find the real problem was the Fuel System Control Module. The symptoms are nearly identical. A faulty FSCM can’t deliver the correct voltage, making the pump appear weak or dead. By starting with this pre-programmed module, you’re not just replacing a part; you’re eliminating the most common and often misdiagnosed point of failure in the GM fuel system, saving you time, money, and frustration.”
Frequently Asked Questions
Do I need to program this module after I receive it?
Absolutely not. The main benefit of our service is that we program the module to the specific VIN you provide during checkout. It will arrive ready to be installed, making it a true plug-and-play solution.
Where is the FSCM located on my truck or SUV?
On most GM trucks and full-size SUVs like the Sierra, Silverado, Tahoe, and Yukon, the FSCM is mounted on the driver’s side frame rail, often above the spare tire. It’s exposed to the elements, which is a common reason for its failure. Always disconnect the battery before beginning the replacement.

After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Will this fix a P069E code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded OFF) is one of the most common codes indicating a failed FSCM. Replacing the module with this pre-programmed unit is the correct and most effective repair for this code.
