If your 2010-2012 Express 1500 Van is suddenly stalling, refusing to start, or flashing a ‘Reduced Engine Power’ message, you’re likely dealing with a failed Fuel System Control Module (FSCM). I’ve seen this exact scenario countless times in my 20+ years as a technician. These modules, often mounted on the frame rail, are exposed to harsh conditions, leading to internal failures that can mimic a bad fuel pump. Don’t waste money replacing parts you don’t need. This is the direct, reliable solution to get your workhorse van back in service.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and high dealership costs out of the equation. By providing us with your vehicle’s VIN at checkout, we will program this module with the latest GM software specifically for your van. This means when it arrives, it’s a true plug-and-play fix. You avoid the expensive tow to the dealer and the $150+ programming fee they charge. For a professional mechanic, this means faster bay turnover. For a DIYer, it means you can confidently complete the job in your own driveway.
Case Study: The Misdiagnosed Fuel Pump
A customer brought in his 2011 Silverado with a classic no-start condition. He’d already replaced the in-tank fuel pump himself, but the truck still wouldn’t fire up. He was frustrated and out a few hundred dollars. After a quick scan, I pulled code P069E – Fuel Pump Control Module Commanded OFF. The module wasn’t sending the signal. The culprit wasn’t the new pump, but the original, corroded FSCM on the frame rail. We installed a pre-programmed module, and the truck started on the first try. This is a perfect example of why diagnosing the 2010-2012 Express 1500 FSCM first can save you significant time and money.

Your Straightforward FSCM Installation Guide
Replacing the 2010-2012 Express 1500 FSCM is a manageable job for anyone with basic tools. It’s typically located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FSCM on the inside of the driver-side frame rail. It’s a small, black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical harnesses. Then, remove the bolts or nuts holding the module to the frame. Corrosion might make this tricky, so a little penetrating oil can help.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location. Secure it with the original hardware.
- Reconnect: Plug the electrical connectors firmly into the new module. You should hear a click as they seat.
- Final Step: Reconnect the negative battery terminal. The vehicle may require a few key cycles for all systems to reset. Start the engine and verify the fix.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is essential for us to program the module with the exact software and calibrations your vehicle requires from the factory. This ensures perfect communication between the FSCM and other vehicle computers, guaranteeing a seamless, plug-and-play installation without any additional programming.
Is this a difficult part to replace myself?
Not at all. For most DIYers with basic hand tools, this is a very straightforward repair. The module is usually in an accessible location on the frame rail. Since our module comes pre-programmed, you eliminate the most difficult part of the job—the software flashing.
Will this fix a P069E code?
Yes, Diagnostic Trouble Code (DTC) P069E is one of the most common indicators of a failing Fuel System Control Module. Replacing a faulty FSCM with this pre-programmed unit is the definitive fix for this code and related symptoms.
What happens if I install it without programming?
An unprogrammed module will not work. The vehicle’s security system will prevent it from starting, or it will not be able to properly regulate the fuel pump, leading to the same issues you’re trying to fix. Our pre-programming service handles this for you.
Is this compatible with other part numbers?
Yes, this module is a direct, interchangeable replacement for several GM part numbers, including 20791901, 20827745, 20877116, and 20850927. Ordering this part ensures you receive a compatible unit for any of these original numbers.
