Is Your 2008-2009 Tahoe Stalling, Hesitating, or Refusing to Start?
If you’re experiencing erratic engine behavior, a sudden loss of power, or a frustrating no-start condition in your Chevrolet Tahoe or other compatible GM vehicle, a faulty Fuel Pump Control Module (FPCM) is a very likely culprit. This critical component, also known as a Fuel System Control Module (FSCM), is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can starve your engine of fuel, leading to a host of performance issues and diagnostic trouble codes. Don’t replace a perfectly good fuel pump—diagnose the system correctly and replace the component that’s actually at fault.
This is a genuine OEM replacement FPCM, part number 20850907, that comes professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This means you get a true plug-and-play solution without the need for an expensive trip to the dealership for programming. We handle the complex part so you can get your truck or SUV back on the road quickly and confidently.
From the Diagnostic Bay
We had a 2008 GMC Sierra 1500 towed in with a classic ‘crank-no-start’ complaint. The owner had already spent a weekend replacing the in-tank fuel pump, only to have the exact same problem. He was frustrated and out a few hundred dollars. We hooked up our scan tool and saw DTC P069E set in the ECM, which points directly to a communication issue with the FPCM. A quick check of the module, mounted on the driver’s side frame rail, showed heavy corrosion on the casing and connector. We swapped in a VIN-programmed module, cleared the codes, and the truck fired up on the first try. It’s a textbook example of how a small, often overlooked module can mimic a major component failure. Always check the FPCM first!
Common Symptoms of a Failing FPCM
- ✔ Engine stalls unexpectedly, especially under load or when coming to a stop.
- ✔ Vehicle cranks but will not start.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Rough or unstable idle.
- ✔ Check Engine Light is illuminated with codes like P069E, P0230, or P025A.
- ✔ Reduced engine power and poor fuel economy.
- ✔ A buzzing or whining noise from the fuel pump that is inconsistent.
Why Choose a VIN-Programmed 2008-2009 Tahoe Fuel Pump Module?
The FPCM on modern GM vehicles is a smart device that communicates with the Engine Control Module (ECM) over a CAN bus network. It’s not a simple relay. The module must be loaded with the correct software and calibration files that match your vehicle’s specific configuration, including engine size, fuel system type, and other options. Attempting to install a used or non-programmed module will result in a no-start condition and communication errors. Our service eliminates this entire headache. By providing your VIN during checkout, you receive a part that is 100% ready for installation right out of the box. Simply disconnect the old module, mount the new one, plug it in, and you’re done.

Frequently Asked Questions
Is this module ready to install right out of the box?
Yes! As long as you provide us with your 17-digit VIN when you place your order, we will program the module with the latest GM software specific to your vehicle. It will be a true plug-and-play installation with no additional steps required.
Where is the FPCM located on my 2008 Tahoe?
On most GM full-size trucks and SUVs from this era, including the Tahoe, Yukon, Silverado, and Sierra, the Fuel Pump Control Module is typically mounted to the driver’s side frame rail, roughly underneath the driver’s door area.
What happens if I don’t provide my VIN?
We cannot ship the module without a VIN because the programming is essential for the part to function in your vehicle. An unprogrammed module will not allow the engine to start. Please be sure to include your VIN in the order notes or send it to us via message after your purchase to avoid delays.
Will this fix a P069E trouble code?
The Diagnostic Trouble Code (DTC) P069E, ‘Fuel Pump Control Module Commanded On,’ is one of the most common codes indicating a failed FPCM. While you should always perform a complete diagnosis, replacing the FPCM is the specified repair for this code in the vast majority of cases.
Do I need any special tools for installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts, are all that’s needed. The most important part is safely securing the vehicle on jack stands or a lift to gain access to the frame rail where the module is located.
