Is Your GM Truck or SUV Stalling, Cranking with No Start, or Showing a P069E Code?
If you’re dealing with frustrating fuel delivery problems on your 2010-2012 GM vehicle, a faulty Fuel System Control Module (FSCM) is a very common culprit. Many owners and even shops mistakenly replace the fuel pump first, only to find the issue persists. In my 20+ years as a diagnostic technician, I’ve seen this exact scenario play out hundreds of times. The FSCM, often mounted on the frame rail, is exposed to the elements, leading to corrosion and internal failure that mimics a bad fuel pump.
From the Shop Floor: “A customer’s 2011 Silverado 1500 came in on a tow truck last month. It would crank all day but wouldn’t fire up. The check engine light was on with code P069E (Fuel Pump Control Module Commanded OFF). They had already replaced the in-tank fuel pump themselves, but nothing changed. 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 fired up on the first try. It’s a fix I’ve performed on countless Tahoes, Sierras, and Escalades.”

Easy Installation for the DIYer or Professional
Installing your new Programmed GM FSCM is a straightforward process that can be done with basic hand tools. Getting it right ensures your vehicle runs reliably for years to come.
Expert Pro Tip: Before installing your new FSCM, take a moment to thoroughly clean the mounting surface on the frame rail. Use a wire brush to remove any rust or scale. A clean, solid ground connection is absolutely critical for the longevity and proper function of this module. Poor grounding is a leading cause of repeat failures.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Old Module: On most trucks and SUVs (like the Silverado, Sierra, Tahoe, Yukon), the FSCM is mounted on the driver’s side frame rail, typically near the spare tire. On other vehicles (like the CTS, LaCrosse, Acadia), it may be in the trunk or rear compartment area. Refer to your specific model’s service information if unsure.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, unbolt the old module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed FSCM into place, ensuring it’s secure. Reconnect the electrical connectors until they click, confirming a solid connection.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting) for 10 seconds to allow the system to initialize, then start your engine. Your fuel delivery issues should be resolved.
