Is Your GM Truck or SUV Stalling or Refusing to Start?
If you’re dealing with frustrating issues like your engine cranking but not starting, sudden stalling, a “Service Stabilitrak” or “Reduced Engine Power” message, or a P069E trouble code, the culprit is very often a failed Fuel System Control Module (FSCM). In my 20+ years as a technician, I’ve seen this exact scenario play out hundreds of times, especially on GM trucks and SUVs where the module is mounted on the frame rail, exposed to water, salt, and road debris. This exposure leads to internal corrosion and eventual failure, leaving you stranded.

From the Shop Floor: A Real-World Diagnosis
“A customer’s 2011 Silverado 1500 came into my shop last week. It would crank fine but wouldn’t start. The fuel gauge was reading correctly, but we weren’t getting the right fuel pressure. The scan tool showed a persistent P069E code, which points directly to the FSCM. Before condemning the module, we checked the connectorโa common failure point. It was clean, but a quick voltage check confirmed the module wasn’t sending the correct signal to the fuel pump. We installed one of our pre-programmed modules, and the truck fired right up on the first try. This is a textbook FSCM failure, and having a VIN-programmed part on hand saved the customer hundreds in diagnostic and programming fees at the dealer.”
Symptoms of a Failing GM Fuel Control Module
If you’re experiencing any of the following, a faulty FSCM is the most likely cause:
- โ Engine cranks but will not start
- โ Vehicle starts and then immediately stalls
- โ “Reduced Engine Power” warning light is on
- โ Check Engine Light with codes like P069E, P0230, or U0109
- โ Inconsistent fuel pressure readings
- โ Hesitation or stumbling during acceleration
Plug-and-Play Installation: No Dealer Visit Required
Replacing the FSCM is a job most DIYers can handle in their own driveway. Hereโs a general guide for a frame-mounted module (location may vary by model):
- Safety First: Disconnect the negative battery terminal.
- Locate the Module: On most trucks and SUVs (Silverado, Sierra, Tahoe, Yukon, Escalade), the FSCM is mounted on the driver’s side frame rail, often near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connector. Inspect it for any green or white corrosion and clean it with an electrical contact cleaner if necessary. Then, unbolt the old module from the frame.
- Install the New Module: Bolt your new, pre-programmed FSCM into place. Reconnect the electrical connector, ensuring it clicks securely.
- Final Steps: Reconnect the negative battery terminal. The vehicle may take a few extra seconds of cranking on the first start as the system re-pressurizes. Your check engine light should be off, and the problem resolved.
