Is Your GM Truck, Van, or SUV Cranking But Not Starting?
There’s nothing more frustrating than a vehicle that won’t run, especially when you depend on it for work or family. If your Chevy Express, Silverado, Tahoe, or other compatible GM vehicle is experiencing intermittent stalling, hesitation on acceleration, or a complete no-start condition, a faulty Fuel System Control Module (FSCM) is the most likely culprit. Don’t let a small electronic component keep you sidelined. This is the direct, reliable solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A failing FSCM can trigger a variety of confusing symptoms and diagnostic trouble codes (DTCs). You might be dealing with a check engine light for codes like P069E, P0230, P0606, or U0109 (Lost Communication With Fuel Pump Control Module). Physically, you may experience:
- Engine cranks but will not start
- Vehicle starts and then immediately stalls
- Sudden loss of power while driving
- Hesitation or sputtering under load
- Reduced fuel economy
This programmed 20791901 fuel system control module is the definitive fix for these issues. We take the guesswork and hassle out of the repair by pre-programming the unit to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive towing, no waiting for a dealership appointment, and no surprise programming fees. It’s a true plug-and-play repair you can perform yourself.

Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians will then use certified equipment to load the correct, most up-to-date GM software for your specific vehicle onto the module before we ship it to you.
Is this part truly plug-and-play?
Yes. Because we pre-program it to your VIN, it is ready for installation right out of the box. Simply disconnect the battery, remove your old module, install this new one, reconnect the battery, and you’re done. No further programming or calibration is required.
Will this fix a Check Engine Light with code P069E?
Yes, P069E (Fuel Pump Control Module Commanded On) 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.
Where is the FSCM located on my truck or SUV?
On most compatible GM trucks and SUVs like the Silverado, Sierra, Tahoe, and Yukon, the Fuel System Control Module is mounted on the driver’s side frame rail, typically above the spare tire. It’s exposed to the elements, which is a common reason for its failure.
What part numbers does this module replace?
This unit is a direct replacement for several original GM part numbers, including 20791901, 20827745, 20877116, and 20850927. If your original module has any of these numbers, this part is a guaranteed fit.
