Common Symptoms & Your Solution
A failing FSCM can manifest in several ways, often triggering diagnostic trouble codes (DTCs) and dashboard warnings. If you’re experiencing any of the following, this module is the likely fix:
- Engine cranks but won’t start
- Sudden stalling while driving, especially under load
- Hesitation or sputtering during acceleration
- Reduced engine power and poor fuel economy

- “Service Fuel System” message on the instrument cluster
Our process is simple: after your purchase, you provide us with your vehicle’s VIN.

From the Tech’s Bench: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched modules. The FSCM doesn’t just power the fuel pump; it’s a networked computer that talks to the Engine Control Module (ECM) and Body Control Module (BCM). Simply installing a used, non-programmed module is a recipe for disaster—it can lead to persistent no-start conditions or even damage your new fuel pump. Our VIN-programming service isn’t just a convenience; it’s a critical step that ensures all systems integrate seamlessly, just as the factory intended. This is the correct way to do the job, ensuring a permanent fix, not a temporary patch.
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not. The main benefit of our service is that we handle all the programming for you before we ship. Simply provide your VIN after purchase, and the module will arrive ready for a plug-and-play installation.
Where is the 20850927 Fuel System Control Module located on my vehicle?
On most trucks and SUVs like the Silverado, Tahoe, and Yukon, it’s typically mounted on the driver’s side frame rail, near the spare tire. On crossovers like the Enclave or Traverse, it’s often found on the rear crossmember. It’s exposed to the elements, which is a primary reason for its failure.
How do I send you my VIN?
After you complete your purchase, you can 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 essential.
Will this fix a P069E trouble code?
Yes, the code P069E (Fuel Pump Control Module Commanded On) is the most common indicator of a failed FSCM. Replacing the module with this pre-programmed unit is the standard and effective repair for this code.
Is this a brand new part?
This is a high-quality, fully tested replacement part that is guaranteed to perform to OEM specifications. Each unit is inspected and programmed by our technicians to ensure it’s ready for years of reliable service.
