Is Your GM Truck or SUV Stalling or Refusing to Start?
There’s nothing more frustrating than a vehicle that cranks but won’t start, or worse, stalls unexpectedly in traffic. If your 2010-2012 GM vehicle is experiencing these issues, or if your mechanic has found a trouble code like P069E, the culprit is often a failed Fuel System Control Module (FSCM). Before you spend a fortune replacing the entire fuel pump, consider this common failure point. In my 20+ years as a technician, I’ve seen this exact scenario play out hundreds of times.
“A customer’s 2011 Silverado 1500 came in last week on a tow truck. It would crank all day but never fire up. The owner had already replaced the fuel pump himself, but the problem persisted. A quick scan showed code P069E (Fuel Pump Control Module Commanded OFF). We traced it to the original FSCM, which had failed due to corrosion from its location on the frame rail. This pre-programmed module had him back on the road in under an hour, solving the problem he’d been chasing for a week.”
The Simple, Dealer-Free Solution
This isn’t just a replacement part; it’s a complete solution. We take a genuine GM Fuel System Control Module and professionally program it with the latest GM software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This means when it arrives at your door, it’s ready for a true plug-and-play installation. No expensive trips to the dealership for programming, no special tools required. This is the fix that saves you time and money.
Is a Failing GM Fuel Control Module Your Problem?
A faulty FSCM can cause a variety of confusing symptoms. Here are the most common signs I’ve diagnosed in the shop:
- โ Vehicle cranks but will not start.
- โ Engine stalls while driving, sometimes intermittently.
- โ Reduced engine power or poor acceleration.
- โ Check Engine Light is on with codes like P069E, P0230, or U0109.
- โ Inconsistent fuel pressure readings.
Plug-and-Play Installation: Get Back on the Road Fast
You can install this module yourself with basic hand tools. While the exact location varies by model (check your service manual), it’s typically found on the driver’s side frame rail or near the rear crossmember.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Old Module: Find the existing FSCM. On most trucks and SUVs like the Tahoe or Sierra, it’s mounted to the frame. On cars like the CTS or LaCrosse, it may be in the trunk or rear compartment.
- Disconnect and Remove: Carefully unplug the electrical connector and unbolt the module from its mounting point.
- Install the New Module: Bolt your new, pre-programmed module in place and securely plug in the electrical connector.
- Reconnect and Start: Reconnect the battery terminal. Your vehicle should now start and run correctly with fuel delivery restored.
Expert Pro Tip: Ensure a Solid Connection
These modules, especially when frame-mounted, are prone to corrosion at the mounting points and electrical connector. Before installing your new module, take a wire brush and clean any rust or debris from the mounting surface on the frame. Also, inspect the vehicle’s harness connector for any green or white corrosion on the pins and clean it with a quality electronics cleaner. A clean ground and solid connection are critical for the longevity of your new FSCM.
