Restore Your Vehicle’s Performance and Reliability
Are you experiencing frustrating and unpredictable issues with your GM truck or SUV? Problems like engine stalling, hesitation during acceleration, a crank-no-start condition, or an illuminated Check Engine Light can often be traced back to a single, critical component: the Fuel Pump Control Module (FPCM). This module, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel delivery system. When it fails, it can leave you stranded and facing a confusing diagnosis. This replacement module, part number 20850907, is the definitive solution to get your vehicle running smoothly and reliably again.
From the Diagnostic Bay
We once had a 2008 Silverado 1500 towed in with a classic crank-no-start issue. The owner had already replaced the in-tank fuel pump himself, assuming it was the obvious culprit, but the truck still wouldn’t fire up. After confirming he had no fuel pressure at the rail, we checked the FPCM. These modules are mounted on the frame rail, exposed to road salt, water, and vibration, which leads to corrosion and internal failure. A quick scan revealed trouble code P069E, pointing directly to the module. We installed a new, pre-programmed FPCM, and the truck fired up on the first try. The customer could have saved himself hundreds of dollars and a weekend of frustration by diagnosing the module first. This is why we stress the importance of checking the FPCM before condemning the pump.
Is Your GM Truck or SUV Showing These Symptoms?
A failing FPCM can manifest in several ways, often mimicking a bad fuel pump. If you’re noticing any of the following signs, your fuel pump module is the likely cause:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Rough idling or engine sputtering
- ✔ Hesitation or loss of power during acceleration
- ✔ Reduced fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109
The Ultimate Plug-and-Play Solution: Your Programmed 2008-2009 Escalade EXT Fuel Pump Module
What makes this module the best choice for your repair is our professional programming service. Modern vehicles require electronic modules to be specifically calibrated to their Vehicle Identification Number (VIN). Without this programming, a new module simply will not work. Typically, this requires an expensive trip to the dealership for installation and software flashing. We eliminate that step entirely. When you purchase this Escalade EXT Fuel Pump Module from us, you provide your VIN, and we program the unit with the latest, most stable software updates directly from GM. It arrives at your door ready for a true plug-and-play installation, saving you time, towing fees, and costly dealer labor charges.
Why Programming is Non-Negotiable
The FPCM communicates with the Engine Control Module (ECM) to precisely manage fuel pressure. It varies the voltage sent to the fuel pump based on engine load, speed, and other parameters. This complex system requires the correct software to function. An unprogrammed module will not communicate correctly, resulting in a persistent no-start condition. Our VIN-specific programming ensures seamless integration and factory-correct performance from the moment you install it. This is the most critical step for a successful repair, and we handle it for you.
Broad Compatibility Across the GM Lineup
While this is a perfect fit for the 2008-2009 Cadillac Escalade EXT, this versatile FPCM is also the correct component for a wide range of GM trucks and SUVs. It directly replaces a number of original part numbers, including: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. It is compatible with popular models such as the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, Hummer H2, and many more from 2007 to 2009. Please verify the fitment list to ensure it matches your specific vehicle.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is essential for us to load the exact, vehicle-specific software and calibrations from GM into the module. This ensures the FPCM communicates perfectly with your vehicle’s other computers, guaranteeing proper function and avoiding a trip to the dealer.
Is this part ready to install right out of the box?
Yes! Because we pre-program the module to your VIN before shipping, it is a true plug-and-play part. Simply disconnect the battery, unbolt the old module, plug in the new one, and you’re ready to go. No further programming or dealer visits are required.
Where is the FPCM located on my vehicle?
On most compatible trucks and SUVs like the Silverado, Sierra, and Escalade, the Fuel Pump Control Module is located on the driver’s side frame rail, typically above the spare tire. Its placement makes it vulnerable to the elements, which is a common reason for its failure.
Can a bad Escalade EXT Fuel Pump Module cause my engine to crank but not start?
Absolutely. This is one of the most common symptoms. The FPCM controls the power to the fuel pump. If the module fails, it cannot send voltage to the pump, resulting in zero fuel pressure. The engine will turn over freely but will not have the fuel it needs to start.
What are the most common trouble codes for a failing FPCM?
The most definitive diagnostic trouble code (DTC) for a failed FPCM is P069E (Fuel Pump Control Module Commanded OFF). You may also see codes like P0230 (Fuel Pump Primary Circuit Malfunction) or U0109 (Lost Communication With Fuel Pump Control Module).
