If your 2010-2012 Chevy Express 1500 Van is suddenly stalling, struggling to start, or throwing confusing fuel system codes, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless vehicle owners and even professional shops chase their tails, replacing perfectly good fuel pumps when the real culprit was a faulty Fuel System Control Module (FSCM). This isn’t just a replacement part; it’s a direct, reliable solution to restore your van’s performance and get you back to work.
The FSCM is the brain behind your fuel pump, regulating voltage to ensure your engine gets the precise amount of fuel it needs. When it fails, the symptoms can be intermittent and frustrating. That’s why we offer this high-quality FSCM, which solves the biggest headache of the repair process: programming. We handle it for you. Simply provide your van’s VIN at checkout, and we will flash the module with the latest, most stable GM software before it even leaves our facility. This means no expensive trips to the dealership and no special scan tools required for installation. It arrives at your door ready to install.
Case Study: The ‘Bad Fuel Pump’ That Wasn’t
I remember a customer with an ’11 Express work van that was towed into my shop. It would crank but not start. The owner had already replaced the in-tank fuel pump himself over the weekend, but the problem persisted. His frustration was palpable. A quick scan showed DTC U0109 – Lost Communication with Fuel Pump Control Module. Instead of going back to the tank, we went straight to the FSCM mounted on the frame rail. It was heavily corroded from road salt and moisture. We installed a new, pre-programmed FSCM, and the van fired up on the first try. He had spent a whole weekend and hundreds of dollars on a pump he didn’t need. This story is why we emphasize checking the FSCM first—it can save you a world of time and money.
Is Your Express Van Showing These Signs?
A failing FSCM can mimic other fuel system problems. Before you replace your fuel pump, check if you’re experiencing any of these common symptoms. This 2010-2012 Express 1500 FSCM is the definitive fix for:
- ✔ Engine stalling, especially under load or when coming to a stop.
- ✔ Crank-no-start condition where the engine turns over but won’t fire.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ An illuminated Check Engine Light with fuel-related codes.
- ✔ Common Diagnostic Trouble Codes (DTCs) such as P069E, P0230, or U0109.
A Straightforward Guide to Installation
Replacing the FSCM is a job most DIYers can handle with basic tools. Since we program it for you, it’s a true plug-and-play repair.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most Express vans, the FSCM is mounted to the driver’s side (LH) frame rail, roughly under the driver’s door area. You may need to safely lift and support the vehicle for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the old module from the frame. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt your new, pre-programmed FSCM into the same location. Ensure it’s secure.
- Reconnect and Test: Plug the electrical connectors back into the new module. Reconnect the battery terminal. Turn the key to the ‘On’ position for a few seconds to prime the system, then start the engine.
