Is Your Cadillac Stalling or Refusing to Start?
There’s nothing more frustrating than a vehicle that’s suddenly unreliable. If your 2010-2012 Cadillac CTS is experiencing issues like engine stalling, hesitation when you press the gas, an extended crank time, or a complete no-start condition, the problem is very likely a failing Fuel System Control Module (FSCM). This small but critical component is the brain behind your fuel pump, and when it fails, it can leave you stranded. You might also see a check engine light with diagnostic trouble code P069E, a dead giveaway for this issue.
The Dealership-Free Solution is Here
In the past, replacing an FSCM meant a trip to the dealership for expensive programming. We’ve eliminated that step. This is a genuine GM Fuel System Control Module that we program specifically to your vehicle’s VIN before we ship it. It arrives at your door loaded with the latest factory software, ready for a straightforward, plug-and-play installation. You get a permanent fix without the dealer’s high labor costs or appointment delays.
Expert Pro Tip from 20+ Years on the Bench: Before you plug in your new module, take a bright flashlight and carefully inspect the vehicle’s wiring harness connector. I’ve seen countless new modules get damaged immediately because of a corroded or melted connector. Look for any green, chalky residue or darkened, burnt-looking plastic around the pins. If you see any signs of damage, you must repair the connector pigtail first, or you’ll be doing this job again.
Key Symptoms of a Failing FSCM:
- ✔ Sudden engine stalling, especially while driving
- ✔ Vehicle cranks but will not start
- ✔ Hesitation or stumbling during acceleration
- ✔ Check Engine Light with code P069E
- ✔ Inconsistent fuel pressure readings
Plug-and-Play Installation for your 2010-2012 CTS
For the Cadillac CTS, the module is conveniently located, making this a very manageable DIY repair. You don’t need specialized diagnostic tools to complete the job.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On the 2010-2012 CTS, you’ll find the FSCM in the trunk, located in the left-hand rear compartment area, typically behind a trim panel.
- Disconnect and Remove: Carefully unplug the electrical connector. Then, unbolt the old module from its mounting point.
- Install the New Module: Bolt the new, pre-programmed module into place. Securely plug in the electrical connector until it clicks.
- Final Steps: Re-install any trim panels you removed and reconnect the negative battery terminal. Your vehicle is now ready to start.
