Restore Your Van’s Reliability and Performance
If your 2010-2012 Chevrolet Express 1500 is experiencing frustrating issues like stalling, hesitation, or a complete 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 can leave you stranded and disrupt your workday. Don’t let a faulty module dictate your schedule. This is a direct-replacement, fully programmed FSCM that restores factory performance and dependability.
The biggest headache with replacing modern electronic modules is the mandatory, and often expensive, trip to the dealership for programming. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the latest, most stable GM software specific to your Express Van. It arrives at your door ready for a true plug-and-play installation, saving you time, towing fees, and dealership labor costs. This is the smart, efficient solution for both professional mechanics and DIY-savvy van owners.
A Technician’s Notebook: The Intermittent Stall
I had a local delivery driver bring in his 2011 Express 1500 with a problem that was costing him money. The van would run fine for hours, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. There were no consistent warning lights, but a scan revealed a stored history code: P069E (Fuel Pump Control Module Commanded OFF). These intermittent electrical issues are the worst to diagnose. We checked fuel pressure, and it was erratic. Instead of just throwing a fuel pump at it, we focused on the FSCM, which is mounted on the frame rail and exposed to years of road grime and moisture. We swapped in one of our pre-programmed modules, and the van was back in service the same afternoon. The driver called a week later to say the problem was completely gone. A simple module swap saved him from a costly, incorrect fuel pump replacement and got his business back on schedule.
Common Signs of a Failing FSCM
- âś” Engine cranks but will not start.
- âś” Vehicle stalls unexpectedly, especially under load or when warm.
- âś” Noticeable loss of engine power and poor acceleration.
- âś” Rough idle or engine hesitation.
- âś” Check Engine Light illuminated with codes like P069E, U0109, or P0230.
- âś” Reduced fuel economy.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- âś” Locate the Module: On the Express 1500 Van, the FSCM is typically mounted to the driver’s side (LH) frame rail, near the spare tire.
- âś” Disconnect Electrical Connectors: Carefully press the release tabs and pull the electrical connectors straight out from the module. Inspect them for any corrosion or damage.
- âś” Remove the Old Module: Unbolt the module from the frame rail. These bolts can sometimes be rusty, so a little penetrating oil might be helpful.
- âś” Install the New Module: Bolt your new, pre-programmed FSCM securely onto the frame rail.
- âś” Reconnect Everything: Plug the electrical connectors firmly back into the new module until they click. Reconnect your battery terminal.
- âś” Final Step: Cycle the key to the ‘On’ position (without starting) for 10 seconds to allow the system to initialize before starting the engine. The vehicle is now ready to run.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows our technicians to access the exact GM software calibration for your vehicle’s specific configuration. This ensures the module communicates perfectly with your engine computer and fuel pump for optimal performance and efficiency, making it a true plug-and-play part.
Is this part difficult to install myself?
For most of the listed trucks and vans, this is a very DIY-friendly repair. The module is located on the frame rail and is typically accessible with basic hand tools. Since our module comes pre-programmed, you save the most difficult step—the software flashing.
Will this fix a P069E trouble code?
Yes, in a vast majority of cases, a faulty FSCM is the root cause of a P069E code. While you should always perform a proper diagnosis, replacing the module is the most common and effective fix for this specific code.
How do I know if my old module is part number 20827745?
You can check the sticker on your original module. However, this part is also a direct replacement for several other part numbers, including 20791901, 20877116, and 20850927. As long as your vehicle is on our compatibility list, this module will work, as the programming is what truly matters.
What happens if I don’t replace a failing FSCM?
Ignoring a failing FSCM can lead to more severe issues. It can cause the fuel pump to work incorrectly, potentially shortening its lifespan. Most critically, it can result in your vehicle stalling in traffic or leaving you stranded with a no-start condition, which can be a serious safety concern.
