Is Your 2010-2012 Express Van Stalling, Hesitating, or Refusing to Start?
As a mechanic with over two decades of experience, I know there’s nothing more frustrating than a work vehicle that’s unreliable. When your Express 1500 is down, you’re not just inconveniencedโyou’re losing money. Often, the culprit for these maddening fuel delivery issues isn’t the fuel pump itself, but the small black box that controls it: the Fuel System Control Module (FSCM).
Mounted on the left-hand frame rail, this critical component is exposed to everything the road throws at it: water, salt, mud, and constant vibration. Over time, this exposure leads to internal failure or corrosion at the connector, causing a host of problems that can mimic a bad fuel pump.

This Fuel System Control Module arrives at your door fully programmed with the latest GM software updates, specifically matched to your vehicle’s VIN. You provide us with your VIN during checkout, and we handle the complex programming. This means no expensive dealer visit, no programming fees, and no special tools required. It’s the most direct path to getting your van back in service.
Expert Pro Tip: Check the Connector First!
Before you even unbolt the old module, take a close look at the wiring harness connector. I’ve seen countless cases where water intrusion has caused green or white corrosion on the pins. If you find any, clean it meticulously with a small wire brush and electrical contact cleaner before plugging in your new module. Installing a new part into a corroded connector is a recipe for a repeat failure.
Common Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Vehicle starts and then immediately stalls
- โ Severe hesitation or stumbling during acceleration
- โ Check Engine Light with codes like P069E, P0230, or P025A
- โ Reduced engine power message on the dash

- Disconnect and Remove: Carefully unplug the electrical connector. Then, remove the bolts or nuts (usually 10mm or 13mm) holding the old module to the frame.
- Inspect and Clean: As mentioned in our pro tip, thoroughly inspect and clean the harness connector. Ensure it’s dry before proceeding.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the electrical connector, ensuring it clicks securely into place.
