Is Your GM Vehicle Stalling, Hesitating, or Refusing to Start?
There’s nothing more frustrating than a vehicle you can’t rely on. If you’re experiencing erratic engine behavior, a check engine light with fuel-related codes, 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, and when it fails, it can leave you stranded. Don’t settle for guesswork or expensive diagnostic fees. Get the definitive solution and restore your vehicle’s dependability.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your module until we receive this information, as the programming is specific to your exact vehicle.
Is this a plug-and-play installation?
Yes. Because we program the module to your VIN before shipping, it is a true plug-and-play part. No further programming or calibration is required at a dealership. You simply install it, and you’re ready to go.
Where is the Fuel System Control Module located on my vehicle?
On most GM trucks and SUVs, the FSCM is mounted to the driver’s side frame rail, often near the spare tire. On sedans and crossovers, it can be located in the trunk or rear compartment. Always consult a repair manual for your specific model to confirm the exact location.
Will this fix a P069E trouble code?
A P069E code (Fuel Pump Control Module Commanded OFF) is one of the most common indicators of a failed FSCM. While you should always perform a complete diagnosis, replacing the module is the standard and most effective repair for this specific code.
Do I need any special tools to replace this module?
Typically, you will only need basic hand tools like a socket set and ratchet to remove the mounting bolts and disconnect the electrical connector. The most important thing is to disconnect the vehicle’s battery before beginning the repair for safety.
