Is Your GM Truck or SUV Stalling or Refusing to Start?
You turn the key, the engine cranks, but it just won’t fire up. Or maybe it starts, but then sputters and dies unexpectedly on the road. These are classic, frustrating signs of a failing Fuel System Control Module (FSCM), also known as a fuel pump driver module. In my 20+ years as a technician, I’ve seen this exact scenario play out hundreds of times. The FSCM is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leaving you stranded.
This isn’t just a part; it’s a complete, ready-to-install solution. We take a genuine GM-spec module and program it with the very latest factory software, specifically matched to your vehicle’s VIN. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
From the Shop Floor: A Real-World Diagnosis
“A customer’s 2011 Silverado 1500 came in last week on a tow truck. It would crank all day but wouldn’t start. He had already replaced the fuel pump himself, assuming that was the issue, but the problem persisted. A quick scan showed code P069E – Fuel Pump Control Module Requested MIL Illumination. We went straight to the FSCM mounted on the driver-side frame rail. The module was corroded from years of exposure to road salt and moisture. We replaced it with one of our pre-programmed units, and the truck fired up on the first try. This simple part saved him from more guessing and unnecessary expenses.”

Easy Installation Guide for Your 2010-2012 Fuel System Control Module
Replacing the FSCM is a straightforward job you can do in your own driveway. While the exact location varies, it’s typically found on the vehicle’s frame or chassis.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most GM trucks and SUVs (Silverado, Sierra, Tahoe, Yukon), it’s on the driver-side frame rail, often near the spare tire. On cars and crossovers (CTS, Acadia, Enclave), it may be in the trunk area or on a rear crossmember.
- Disconnect and Remove: Unplug the electrical connector(s). Be gentle with the locking tabs. Then, unbolt the module from the frame. These bolts can be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Before tightening fully, it’s wise to clean the mounting points on the frame to ensure a solid ground connection.
- Reconnect and Test: Securely plug in the electrical connector(s). Reconnect the battery terminal. Turn the key to the ‘On’ position for a few seconds to let the system prime, then start the engine.
Expert Pro Tip: The single biggest killer of these frame-mounted modules is a poor ground connection caused by rust and corrosion. Before you bolt your new FSCM on, take a wire brush or some sandpaper and clean the mounting surface on the frame until you see shiny, bare metal. This ensures a solid ground path, which is critical for the module’s long-term health.
After purchase, simply send us your vehicle’s 17-digit VIN, and our experts will handle the programming. We’ll get this critical part shipped to you, ready for a hassle-free installation that restores your vehicle’s reliability.
