Restore Your Truck’s Reliability and Performance
Is your 2008-2009 GMC Sierra Denali or other GM truck suddenly stalling, hesitating, or refusing to start? The frustration of an unreliable vehicle is something I’ve seen countless times in my 20+ years in the shop. More often than not on these vehicles, the culprit isn’t the fuel pump itself, but this small, yet critical, component: the Fuel Pump Control Module (FPCM). This module, often called a Fuel System Control Module (FSCM), is the brain behind your fuel delivery system. When it fails, it can leave you stranded without warning.
We offer a dependable and straightforward solution. This isn’t just a replacement part; it’s a complete fix. We take a genuine GM-spec FPCM and flash it with the very latest official software updates using the Vehicle Identification Number (VIN) from your specific truck. This means you receive a part that is 100% plug-and-play, with no expensive trip to the dealership required for programming. This is the exact process we use in our own repair facility to guarantee a lasting repair.
From the Diagnostic Bay
I remember a 2008 Silverado 1500 that came in on a tow truck. The owner had already replaced the in-tank fuel pump, but the truck would still crank but not start, or sometimes stall while driving. He was frustrated and out of money. A quick scan showed a U0109 ‘Lost Communication with Fuel Pump Control Module’ code. We located the FPCM on the driver-side frame rail, and it was caked in mud and corrosion. After installing one of our pre-programmed modules, the truck fired up on the first try and ran perfectly. It’s a classic failure on these trucks, and having a VIN-programmed module on hand turned a difficult problem into a simple, 20-minute fix.
Is Your Truck Showing These Symptoms?
A failing FPCM can mimic a bad fuel pump. Before you spend hundreds on a pump replacement, check if your vehicle is experiencing any of these common indicators of a bad fuel pump control module. A faulty 2008-2009 Sierra Denali FPCM often leads to:
- ✔ Engine stalling, especially under load or when warm.
- ✔ Extended cranking time before the engine starts.
- ✔ Complete no-start condition where the engine just cranks.
- ✔ Stuttering or hesitation during acceleration.
- ✔ Reduced engine power and poor fuel economy.
- ✔ Check Engine Light with diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109.
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle with basic tools. Because we pre-program the module, you skip the most complicated step. The module is typically located on the driver-side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FPCM mounted to the frame crossmember. It’s a small silver box with an electrical connector.
- Disconnect and Remove: Unplug the electrical connector, being careful not to damage the locking tab. Then, remove the bolts or nuts holding the module to the frame.
- Install the New Module: Bolt the new, pre-programmed FPCM into place. Ensure it is securely mounted.
- Reconnect: Plug the electrical connector firmly into the new module until it clicks. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to prime the system, then start the engine. Your vehicle should now run smoothly.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive your VIN, as the programming is specific to your vehicle.
Why is VIN programming necessary?
The FPCM communicates with your vehicle’s main computer (ECU/PCM). Programming it to your VIN ensures it has the correct software and parameters to control fuel pressure accurately for your specific engine and emissions system, preventing performance issues and error codes.
Is this part difficult to install?
No, this is a very DIY-friendly repair. Since we handle the programming, the physical installation is just a matter of unbolting the old module and bolting in the new one. It typically takes less than 30 minutes with basic hand tools.
What is the most common cause of FPCM failure?
The most common cause is exposure to the elements. These modules are often mounted on the vehicle’s frame rail, where they are subjected to water, salt, and road debris, leading to corrosion and internal electronic failure.
Will this fix a P069E check engine light code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded On) is one of the most common codes indicating a faulty FPCM. Replacing the module with our pre-programmed unit is the definitive fix for this issue.
