Is Your Express Van Stalling, Cranking with No Start, or Showing a P069E Code?
As a mechanic with over two decades of experience, I know that when a workhorse like your 2010-2012 Express 1500 is down, every minute costs you money. Intermittent stalling, a crank-no-start condition, or a check engine light with fuel system codes can often be traced back to a single, critical component: the Fuel System Control Module (FSCM), also known as the fuel pump driver module. This isn’t just a simple relay; it’s the brain that precisely controls the fuel pump’s voltage and speed, ensuring your engine gets the exact amount of fuel it needs under all conditions.
Expert Pro Tip: Check for Corrosion First
On these Express and Savana vans, the FSCM is mounted on the left-hand frame rail, right in the line of fire for road salt, water, and grime. Before you condemn the module, inspect the electrical connector thoroughly. I’ve seen countless cases where the pins inside the harness connector were green with corrosion, causing the exact same symptoms as a failed module. Cleaning the connector with a terminal brush and applying dielectric grease is a crucial step for a lasting repair.
The Problem with a Standard Replacement
You can’t just buy a new FSCM off the shelf and expect it to work. Each module is tied to the vehicle’s specific VIN and requires programming with the latest GM software to communicate with the Engine Control Module (ECM) and other vehicle systems. Without this critical programming step, your van simply won’t run correctly, if at all. This typically means a costly trip to the dealership for installation and programming, adding more downtime and expense to your repair.
