Restore Your Engine’s Performance and Reliability
Is your 2013 Cadillac Escalade EXT or another GM vehicle suffering from frustrating and unpredictable engine problems? Symptoms like sudden stalling, difficulty starting, engine hesitation under load, or a persistent Check Engine Light can often point to a single, critical component: a failing Fuel Pump Control Module (FPCM). This module, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel delivery system. It precisely regulates the voltage sent to the fuel pump, ensuring your engine receives the exact amount of fuel it needs for optimal performance and efficiency. When it fails, it can leave you stranded and facing a complex repair.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealer-dependency out of the equation. Each 2013 Escalade EXT Fuel Module is professionally programmed with the latest official GM software updates. All we need is your vehicle’s VIN at checkout. This ensures perfect communication with your vehicle’s other computers, like the ECM and BCM, right out of the box. You get a reliable fix that restores factory performance without the added time and expense of a trip to the dealership for programming.
A Technician’s Notebook: The Intermittent Stall
I had a 2013 Silverado in the bay with a complaint that stumped two other shops: it would stall randomly at stoplights, but only when the weather was hot. There were no consistent codes, just an occasional P069E (Fuel Pump Control Module Commanded Off). We checked the fuel pump, wiring, and pressure, and everything seemed fine. On a hunch, I focused on the FPCM, which is mounted on the frame rail—exposed to heat and moisture. After letting the truck idle for 30 minutes on a hot day, I tapped the module with a screwdriver handle, and the engine immediately sputtered and died. The heat was causing an internal failure in the module’s circuitry. Replacing it with a pre-programmed unit like this one solved the problem permanently. It’s a classic failure I’ve seen dozens of times on these GM platforms.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but refuses to start (no-start condition).
- ✔ Sudden engine stalling, especially when coming to a stop or at idle.
- ✔ Noticeable hesitation or sputtering during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ An illuminated Check Engine Light with fuel system-related Diagnostic Trouble Codes (DTCs) such as P069E, P0230, P0627, or U0109.
Plug-and-Play Installation: A Straightforward Guide
Installing your new 2013 Escalade EXT Fuel Module is a manageable job for a confident DIYer or a quick task for any professional mechanic. On most trucks and SUVs, the module is located on the driver-side frame rail.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the FPCM. On most compatible trucks (Silverado, Sierra, Escalade, Tahoe), it’s mounted on the left (driver’s side) frame rail, often near the spare tire. On cars or crossovers (CTS, Acadia), it may be in the trunk or on a rear crossmember.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, remove the bolts or nuts holding the module to its bracket. Corrosion can be an issue here, so a little penetrating oil can help.
- Install the New Module: Mount your new, pre-programmed FPCM in the same location. Secure it with the original hardware.
- Reconnect and Finalize: Plug the electrical connectors back in until they click securely. Reconnect the negative battery terminal. The vehicle is now ready to start with no additional programming required.

Frequently Asked Questions
What is the benefit of this module being pre-programmed?
It saves you significant time and money. A new module from a dealer would require a separate, costly programming session. Our module arrives ready for installation, making it a true plug-and-play fix that communicates correctly with your vehicle’s systems immediately.
Do I really need to provide my VIN?
Yes, providing your 17-digit Vehicle Identification Number (VIN) is essential. We use it to load the exact, correct GM software for your specific vehicle build, ensuring flawless operation and compatibility.
Where is the FPCM located on my 2013 Escalade EXT?
On the 2013 Escalade EXT, as with most GM trucks of this era, the Fuel Pump Control Module is mounted to the left (driver’s side) frame rail, typically ahead of the rear axle.
Can a bad FPCM cause a no-start condition?
Absolutely. The FPCM is responsible for powering the fuel pump. If the module fails completely, it won’t send power to the pump, and the engine will crank but will not start due to a lack of fuel.
Is this part compatible with part number 20964305?
Yes, this module is a fully compatible and interchangeable replacement for both 20964304 and 20964305.
