Is Your 2012 Impala Stalling, Hesitating, or Refusing to Start?
There’s nothing more frustrating than an engine that cranks but won’t fire up, or one that cuts out unexpectedly in traffic. If you’re experiencing these symptoms, along with a “Service Fuel System” message or a check engine light with code U0109 (Lost Communication With Fuel Pump Control Module), the culprit is often a failed Fuel System Control Module (FSCM). This small but critical component is the brain that tells your fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to serious drivability problems.
From the Shop Floor: “A customer’s 2012 Impala came in last week with a classic no-start condition. They had already replaced the fuel pump, but the engine still wouldn’t catch. A quick scan confirmed a hard U0109 code. We located the FSCM in the trunk’s right rear quarter panel, swapped it with a pre-programmed unit just like this one, and the car fired right up. It’s a common failure point I’ve diagnosed hundreds of times, and a new module is the definitive fix.”

Simple Installation: No Dealer Visit Required
You can install this module yourself with basic hand tools. Hereโs a general guide for your 2012 Impala:
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Access the Module: Open the trunk and pull back the liner on the right-hand (passenger) side to expose the FSCM mounted in the quarter panel area.
- Disconnect and Remove: Carefully unplug the electrical harnesses connected to the old module. Then, remove the bolts or nuts holding it in place.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and securely fasten it.
- Reconnect Everything: Plug the electrical connectors firmly into the new module. Reconnect your battery’s negative terminal.
- Verify the Fix: Start your Impala. It should run smoothly, and any related warning lights should be extinguished.
Expert Pro Tip: Before installing your new FSCM, take a moment to inspect the electrical connectors on the vehicle’s wiring harness. Look for any green or white crusty buildup (corrosion) or bent pins. A poor connection can mimic module failure. Cleaning the terminals with a dedicated contact cleaner can prevent future issues and ensure a solid repair.
