Is Your Buick Enclave Stalling, Hesitating, or Refusing to Start?
If you’re dealing with frustrating engine problems like stalling at intersections, poor acceleration, or a car that just won’t turn over, a failing Fuel System Control Module (FSCM) is a very likely culprit. In my 20+ years as a technician, I’ve seen these exact symptoms hundreds of times, often accompanied by the dreaded P069E, P0230, or P0606 trouble codes. The FSCM is the electronic brain that tells your fuel pump how much fuel to deliver. When it fails, your engine is starved of fuel, leading to unreliable performance and leaving you stranded.

From the Shop Floor: A Common Diagnostic Mistake
“A customer’s 2011 Enclave came in last week with intermittent stalling and a P069E code. They had already replaced the fuel pump themselves, but the problem persisted. The issue wasn’t the pump; it was the 2010-2012 Enclave FSCM. On these vehicles, the module is mounted to the rear crossmember, exposed to road salt and moisture. His original module’s connector pins were green with corrosion, causing a poor connection and erratic fuel pressure. We installed one of our pre-programmed modules, and the vehicle ran perfectly. Always check the FSCM and its connector for corrosion before condemning the fuel pump โ it can save you hundreds of dollars.”
Symptoms of a Failing FSCM:
- โ Engine cranks but will not start
- โ Stalling, especially under load or when coming to a stop
- โ Rough idle and engine hesitation
- โ Reduced engine power and poor fuel economy
- โ Check Engine Light with codes like P069E, P0230, or U0109
Plug-and-Play Installation: No Dealer Visit Required
Installing your new 2010-2012 Enclave FSCM is a straightforward process you can do at home. Hereโs a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On the 2010-2012 Enclave, the FSCM is typically mounted on the rear subframe/crossmember, near the fuel tank.
- Disconnect: Carefully unplug the electrical connector(s) from the old module. Inspect the harness-side connector for any signs of corrosion or damage and clean if necessary.
- Remove Old Module: Unbolt the old FSCM from its mounting bracket. It’s usually held on by a couple of small bolts.
- Install New Module: Bolt the new, pre-programmed FSCM into place.
- Reconnect: Plug the electrical connector(s) firmly into the new module until they click.
- Final Step: Reconnect the negative battery terminal. Start the vehicle to confirm the repair.
