Is Your GM Truck or SUV Stalling, Sputtering, or Refusing to Start?
A reliable fuel supply is the lifeblood of your vehicle’s engine. In modern GM vehicles like the 2008-2009 Chevrolet Tahoe, GMC Sierra, or Cadillac Escalade, the Fuel Pump Control Module (FPCM), sometimes called the Fuel System Control Module (FSCM), is the brain behind this critical operation. It precisely regulates the voltage sent to the fuel pump, ensuring your engine gets the exact amount of fuel it needs under all driving conditions. When this module fails, it can cause a wide range of frustrating and potentially dangerous issues, from poor performance and decreased fuel economy to leaving you stranded on the side of the road.
This replacement FPCM, part number 13501024, is the definitive solution for a faulty original module. Unlike a generic part from a local store, this module is not a one-size-fits-all guess. We provide a crucial service: we flash the module with the latest official GM software, specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN) before it ships. This means it arrives at your door ready for a straightforward installation, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in with a classic ‘crank, no start’ condition. The owner had already replaced the fuel pump himself, assuming it was the culprit, but the problem persisted. He was frustrated and out a few hundred dollars. When we hooked up our scanner, we saw DTC P069E – ‘Fuel Pump Control Module Commanded OFF.’ A quick check of the FPCM, located on the frame rail, revealed heavy corrosion on the casing and connector pins—a very common issue. The module was shorting internally. We installed a new, VIN-programmed module, and the truck fired right up. It’s a powerful reminder to always diagnose before replacing parts; the FPCM is often the root cause of fuel delivery problems, not the pump itself.
Common Symptoms of a Failing FPCM
If your vehicle is exhibiting any of the following symptoms, a failing Fuel Pump Control Module could be the cause. A faulty module can mimic a bad fuel pump, so proper diagnosis is key.
- ✔ Engine cranks but will not start.
- ✔ Stalling, especially under load or during acceleration.
- ✔ Rough idling or engine sputtering.
- ✔ Hesitation or loss of power when accelerating.
- ✔ Check Engine Light with codes like P069E, P0230, P025A, or U0109.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ A loud whining noise from the fuel pump as it runs continuously at full power.
The Right Solution: A Pre-Programmed 2008-2009 Tahoe FPCM
Why is a pre-programmed module so important? The FPCM communicates with your vehicle’s primary computer, the Engine Control Module (ECM), to manage fuel pressure based on engine load, speed, and other parameters. If the software isn’t a perfect match for your vehicle’s specific configuration, it can lead to persistent performance issues, incorrect fuel trims, and even damage to your new fuel pump. Our process ensures a seamless integration. By providing your VIN, you guarantee that the 2008-2009 Tahoe FPCM you receive is loaded with the correct operational parameters for your exact make, model, and engine combination. This is the most reliable and efficient way to restore your vehicle’s factory performance and fuel delivery logic.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This makes the part ready to install right out of the box, saving you the time, hassle, and high cost of dealership programming.
Where is the FPCM located on my vehicle?
On most compatible trucks and SUVs like the Tahoe, Silverado, and Sierra, the FPCM is typically mounted on the driver’s side frame rail, often near or above the spare tire. It’s exposed to the elements, which is a primary reason these modules fail due to corrosion.
What happens if I install this without providing a VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function correctly with your vehicle’s computer system. An unprogrammed module will not work. Please be sure to send us your VIN after purchase to avoid delays.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, safely raising the vehicle, locating the old module, unplugging the electrical connector, and unbolting it from the frame. The new module then bolts in its place. The most important step is ensuring the connector is clean and free of corrosion before plugging in the new module.
Will this fix my P069E trouble code?
The Diagnostic Trouble Code P069E is one of the most common codes indicating a fault within the FPCM circuit. While a failed module is the most frequent cause, it’s also important to check for corroded wiring, a bad connector, or a poor ground connection at the module. In the majority of cases, replacing the FPCM resolves this code.
