Restore Your Van’s Performance and Reliability
Is your 2010-2012 Express 1500 Van experiencing frustrating issues like stalling, hesitation, or a complete no-start condition? A faulty Fuel System Control Module (FSCM) is often the culprit. This critical component, also known as a fuel pump driver module, regulates the voltage sent to the fuel pump. When it fails, it can starve your engine of fuel, leading to poor performance, a check engine light, and leaving you stranded. Don’t let a small electronic module sideline your work van or family vehicle.
We offer a dependable and straightforward solution. This FSCM is not just a replacement part; it’s a complete, ready-to-install fix. We pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives with the latest GM factory software, ensuring perfect communication with your vehicle’s computer systems. You can skip the expensive trip to the dealership for programming and get your van back on the road quickly and affordably.
From the Diagnostic Bay: A Common Pitfall
I’ve seen it hundreds of times in my shop: a customer comes in with a truck or van that cranks but won’t start, or stalls intermittently. They’ve already replaced the fuel pump, sometimes a costly and difficult job, only to have the exact same problem. The real issue, more often than not, is the FSCM. These modules are typically mounted on the frame rail, exposed to water, salt, and road debris, which corrodes the housing and damages the internal electronics. A quick check for power at the fuel pump connector often points directly to a failed FSCM, saving hours of labor and the cost of an unnecessary pump replacement.
Is Your Vehicle Showing These Symptoms?
A failing FSCM can cause a variety of symptoms. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when warm
- ✔ “Reduced Engine Power” message on the dash
- ✔ Hesitation or sputtering during acceleration
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
- ✔ Inconsistent fuel pressure readings
A Straightforward Guide to Installation
Installing your new 2010-2012 Express 1500 FSCM is a job most DIYers can handle with basic tools. On most GM trucks and vans, the module is located on the driver’s side frame rail, making access relatively simple.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the old FSCM. On the Express Van, it’s typically mounted to the inside of the frame rail, near the spare tire.
- Disconnect the Wiring: Carefully unplug the electrical connector(s) from the old module. Press the release tab firmly to avoid breaking it.
- Remove the Old Module: Unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil might be helpful.
- Install the New Module: Bolt your new, pre-programmed FSCM into place. Ensure it’s securely fastened.
- Reconnect and Finalize: Plug the electrical connector(s) into the new module until they click. Reconnect your battery terminal. The vehicle is now ready to start with no further programming needed.
