Is Your GM Truck or SUV Stalling or Refusing to Start?
If you’re dealing with frustrating engine stalls, a crank-no-start condition, or a persistent Check Engine Light with code P069E, the culprit is very likely a failed Fuel System Control Module (FSCM). I’ve seen this exact scenario hundreds of times in my 20+ years as a technician. These modules, often mounted on the driver-side frame rail, are constantly exposed to water, salt, and vibrations, leading to internal corrosion and failure.
A Story from My Shop
“A customer’s 2011 Sierra 1500 came in on a tow truck last week. He’d already replaced the in-tank fuel pump himself, but it still wouldn’t fire up. His scanner showed P069E, but he didn’t know what to make of it. We put it on the lift, and one look at the original FSCM told the storyโthe casing was swollen and the connectors were green with corrosion. We installed one of our pre-programmed modules, and the truck started on the first try. Itโs a common, and often misdiagnosed, problem.”

This isn’t just a replacement part; it’s a complete solution. We take a genuine GM Fuel Control Module and program it with the latest GM software specifically for your vehicle’s VIN. This means it arrives at your door ready for a true plug-and-play installation. You get to skip the expensive dealership visit for programming, saving you time and hundreds of dollars.
Common Symptoms of a Failing GM Fuel Control Module
- โ Engine stalls unexpectedly while driving.
- โ Vehicle cranks but will not start.
- โ Check Engine Light is on with code P069E (Fuel Pump Control Module Commanded OFF).
- โ Reduced engine power or hesitation during acceleration.
- โ Inconsistent fuel pressure readings.
Plug-and-Play Installation: Get Back on the Road Fast
You don’t need to be a master mechanic to replace this module. With basic hand tools, you can have your vehicle running properly in under an hour.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs (like the Silverado, Tahoe, and Escalade), you’ll find the FSCM mounted to the driver-side frame rail, near the spare tire. On other vehicles like the CTS or LaCrosse, it may be in the trunk or rear compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts holding the old module to the frame.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the electrical harnesses, ensuring they click securely.
- Final Step: Reconnect the negative battery terminal. Start the vehicle and confirm the Check Engine Light is off and the engine runs smoothly.
Expert Pro Tip: Connector Inspection
Before plugging in your new module, take a moment to inspect the vehicle’s wiring harness connectors. Use a small pick and some electrical contact cleaner to gently clean out any green or white corrosion from the pins. A poor connection is a common cause of repeat failures, and this simple step ensures a solid, long-lasting repair.
