Restore Your Cadillac’s Performance and Reliability
Is your 2013-2015 Cadillac CTS, or another compatible GM vehicle, suffering from frustrating and unpredictable fuel delivery problems? An engine that cranks but won’t start, hesitates during acceleration, or stalls unexpectedly can point directly to a failing Fuel Pump Control Module (FPCM). This critical component, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel pump, regulating voltage to ensure precise fuel pressure. When it fails, your engine is starved of the fuel it needs to run properly.
As a technician with over two decades of experience, I’ve seen firsthand how a faulty FPCM can mimic other issues, leading to wasted time and money on incorrect diagnoses. This module is your direct-fit, reliable solution. We take the guesswork and extra expense out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives at your door with the latest GM software updates, ready for a straightforward installation without requiring a trip to the dealership for expensive programming.
Is Your Vehicle Showing These Symptoms?
A failing FPCM can cause a range of issues from minor annoyances to leaving you stranded. If you’re experiencing any of the following, this module is the likely solution. I’ve diagnosed hundreds of these failures in my shop, and these are the classic signs:
- ✔ Engine has a long crank time before starting, or fails to start at all.
- ✔ Vehicle stalls intermittently, especially when coming to a stop or under load.
- ✔ Noticeable hesitation or sputtering when you press the gas pedal.
- ✔ “Reduced Engine Power” message appears on your dashboard.
- ✔ An active Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109 (Lost Communication with Fuel Pump Control Module).
- ✔ Inconsistent fuel pressure readings when checked with a diagnostic scanner.
Case Study: The Intermittent 2014 CTS Stall
A customer brought in their 2014 Cadillac CTS with a problem that was driving them crazy: it would stall without warning, usually at a red light. No codes were stored initially. We checked fuel pressure, which seemed fine in the bay. On a long test drive, I finally got it to act up. Monitoring live data, I saw the fuel pump command from the FPCM suddenly drop to zero right before the engine quit. The module, located in the left rear compartment, was overheating and failing intermittently. Replacing the old module with a new, pre-programmed unit like this one solved the problem permanently. The customer was thrilled to have their car back without the constant fear of stalling in traffic.
A Straightforward Guide to Installation
Installing your new 2013-2015 CTS Fuel Pump Module is a manageable job for a DIY enthusiast or a quick task for any professional mechanic. For the Cadillac CTS, the module is typically located in the trunk area, behind the left-side trim panel.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: In the CTS, you’ll need to remove the trunk floor covering and the left-side trim panel to expose the FPCM. It’s a small black box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the electrical connectors securely.
- Reassemble and Test: Reinstall the vehicle’s trim panels. Reconnect the battery terminal. Turn the key to the ‘On’ position for a few seconds to allow the fuel system to prime, then start the engine. Your vehicle should now run smoothly.

Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. This module is fully programmed to your car’s VIN before we ship it. It is a true plug-and-play solution, saving you a trip to the dealer.
What information do you need from me?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we have this information to program it correctly.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a failed FPCM. Replacing the module is the standard, effective repair for this code.
Where is this module located on a 2014 Chevy Tahoe?
On GM trucks and SUVs like the Tahoe, Yukon, and Silverado from this era, the FPCM is typically mounted to the driver’s side frame rail, near the spare tire. It is exposed to the elements, which is a common reason for its failure.
Is this a genuine GM part?
This is a high-quality replacement part that is programmed with official GM software updates. It is designed to meet or exceed original equipment specifications for function and reliability.
