If your 2010-2012 Chevrolet Express 1500 Van is experiencing frustrating issues like engine stalling, a no-start condition, or a check engine light with fuel-related codes, a failing Fuel System Control Module (FSCM) is a very common culprit. This critical component, often called the fuel pump driver module, regulates the voltage sent to your fuel pump. When it fails, it can leave you stranded and your work van out of commission. Don’t waste time and money guessing or paying for expensive dealership diagnostics and programming fees. This is the direct, reliable solution you need.
We offer a genuine OEM-quality Fuel System Control Module that arrives at your door pre-programmed to your van’s specific Vehicle Identification Number (VIN). By flashing the module with the latest GM software updates before it ships, we eliminate the need for a trip to the dealer or the use of a specialized scan tool. This makes the repair process faster, more affordable, and accessible for both professional technicians and DIY-savvy van owners. Restore your vehicle’s performance and reliability with a part designed for a perfect fit and seamless operation.
From the Diagnostic Bay
I remember a fleet customer with a 2011 Express 1500 that was a real headache. The van would run fine for a while, then suddenly stall in traffic and refuse to restart for 20 minutes. The driver was losing work, and the shop had already replaced the fuel pump with no change. They brought it to us, and the scanner was showing an intermittent U0109 (Lost Communication with Fuel Pump Control Module) and P069E (Fuel Pump Control Module Requested MIL Illumination). Instead of just throwing another part at it, we checked the FSCM. It’s mounted on the frame rail, exposed to road salt and moisture. Sure enough, there was corrosion at the connector. We installed one of our VIN-programmed modules, and the van has been running reliably ever since. It’s a classic failure on these workhorses.
Is Your Express Van Showing These Symptoms?
A failing FSCM can mimic other fuel system problems. Here are the most common indicators that point directly to this module being the issue:
- ✔ Engine cranks but will not start
- ✔ Stalling while driving, especially under load
- ✔ Hesitation or stumbling on acceleration
- ✔ Reduced engine power and performance
- ✔ Check Engine Light with codes like P069E, U0109, P0230, or P0606
- ✔ Inconsistent fuel pressure readings
A Straightforward Guide to Installation
Replacing the 2010-2012 Express 1500 FSCM is a job most DIYers can handle with basic tools. Since our module comes pre-programmed, you can skip the complex software steps.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On the Express Van, the FSCM is typically mounted to the driver-side frame rail, near the fuel tank.
- Disconnect: Carefully unclip the electrical connectors from the old module. Inspect the connectors for any signs of corrosion or damage.
- Remove Old Module: Unbolt the old FSCM from the frame. It’s usually held on by two or three small bolts.
- Install New Module: Mount your new, pre-programmed FSCM onto the frame rail and tighten the bolts securely.
- Reconnect: Plug the electrical connectors firmly into the new module until they click into place. Applying a small amount of dielectric grease can help prevent future corrosion.
- Final Step: Reconnect the negative battery terminal. The vehicle is now ready to start with no further programming required.

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 compatibility and function, just like a dealership would provide, but without the hassle.
Is this a plug-and-play part?
Yes! Because we program it to your VIN before shipping, it is a true plug-and-play solution. Simply install it, and you’re ready to go. No additional programming is needed.
Where is the FSCM located on my 2011 Express 1500?
On the 2010-2012 Express and Savana vans, the Fuel System Control Module is located on the outside of the driver-side frame rail, usually a bit forward of the rear axle.
Can a bad FSCM drain my battery?
While less common, it’s possible. An internally shorted module could potentially cause a parasitic draw on the battery. However, the primary symptoms are almost always related to engine starting and running performance.
What happens if I install this without programming?
An unprogrammed module will not communicate correctly with your vehicle’s other computers, like the ECM. This will result in a no-start condition and communication error codes. Our pre-programming service solves this entire problem for you.
