Restore Proper Fuel Delivery to Your GM Truck or SUV
Is your 2008-2009 Chevrolet Avalanche, Silverado, Tahoe, or other compatible GM vehicle experiencing frustrating issues like engine stalling, hesitation during acceleration, a no-start condition, or a persistent Check Engine Light? These are classic symptoms of a failing Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). This critical component is responsible for precisely managing the voltage sent to your fuel pump, ensuring your engine receives the exact amount of fuel it needs under all driving conditions. When it fails, it can leave you stranded and facing a difficult diagnosis.
This replacement FPCM, part number 20759945, is the definitive solution to restore your vehicle’s performance and reliability. Unlike parts that require a trip to the dealership for expensive programming, this module arrives at your door completely pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). We handle the complex flashing process with the latest GM software updates, making this a true plug-and-play repair for both professional technicians and savvy DIYers.
From the Diagnostic Bay
We had a 2009 Sierra 1500 towed in with a classic no-start complaint. The owner had already replaced the in-tank fuel pump himself, assuming it was the culprit, but the truck still wouldn’t fire up. A quick scan revealed a P069E code: ‘Fuel Pump Control Module Commanded OFF’. We checked the wiring and found it intact. The issue was the FPCM itself, which had failed internally. These modules are exposed to harsh conditions on the frame rail and are a common point of failure. By installing a pre-programmed FPCM like this one, we had the customer back on the road in under an hour, saving him the cost of the unnecessary fuel pump and the headache of a dealership visit for programming.
Diagnosing a Failing Avalanche Fuel Pump Module
A faulty FPCM can mimic other fuel system problems, making diagnosis tricky. If you’re experiencing any of the following, your fuel pump module is a likely suspect:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Rough or erratic idle
- ✔ Hesitation or stumbling on acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with fuel system codes (e.g., P069E, P0230, P025A)
- ✔ A buzzing or whining noise from the fuel pump area that is inconsistent
The Pre-Programmed Advantage
Modern GM vehicles utilize a sophisticated variable-pressure fuel system. The FPCM is the brain of this system. A generic, unprogrammed module simply will not work. It must be calibrated with software that matches your vehicle’s engine, transmission, and other specific options. Our service eliminates this critical, and often overlooked, step. By providing us with your VIN during checkout, you receive a module that is ready for immediate installation. This saves you time, money, and the hassle of coordinating with a dealership or specialized shop with expensive programming tools.
Simple Installation Process
For most trucks and SUVs like the Avalanche, Sierra, and Yukon, the FPCM is located on the driver’s side frame rail, near the spare tire. Installation is straightforward:
- Safety First: Disconnect the negative battery terminal.
- Locate the Module: Find the old module on the frame rail. It’s a small black box with electrical connectors.
- Disconnect and Remove: Unplug the electrical connectors and unbolt the module from the frame.
- Install the New Module: Bolt the new, pre-programmed module in place and securely reconnect the electrical harnesses.
- Final Step: Reconnect the battery terminal. Your vehicle is ready to start.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. The main benefit of this part is that we program it for you before shipping. Simply provide your vehicle’s VIN at checkout, and it will arrive ready to install right out of the box.
Where is the FPCM located on my 2008 Silverado 1500?
On most GM trucks and full-size SUVs from this era, including the Silverado, the Fuel Pump Control Module is mounted to the driver’s side frame rail, typically above or near the spare tire.
Can a bad FPCM cause a P069E code?
Yes, absolutely. Diagnostic Trouble Code P069E is one of the most common codes indicating a problem within the FPCM circuit, often pointing directly to a failed module.
Why is providing my VIN so important?
Your VIN allows us to load the precise GM factory software and calibrations for your vehicle’s specific configuration (engine, drivetrain, emissions, etc.). This ensures seamless communication with other vehicle computers and guarantees correct fuel system operation.
Is this part the same as a fuel pump driver module?
Yes. The terms Fuel Pump Control Module (FPCM), Fuel System Control Module (FSCM), and Fuel Pump Driver Module (FPDM) are often used interchangeably for this component.
