Restore Your Truck’s Performance and Reliability
Is your 2008-2009 Sierra Denali, or another compatible GM truck, suddenly stalling, hesitating during acceleration, or refusing to start? Before you suspect the fuel pump itself, the culprit is often the Fuel Pump Control Module (FPCM), also known as a Fuel Pump Driver Module. Mounted on the frame rail, these modules are exposed to harsh road conditions—water, salt, and debris—which leads to internal corrosion and failure. This results in erratic fuel pressure, leaving you stranded and frustrated. In my 20+ years in the shop, I’ve seen this exact failure hundreds of times on otherwise perfectly healthy GM trucks and SUVs.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM-spec module and flash it with the very latest official software updates using the VIN you provide. This critical step ensures perfect communication with your vehicle’s computer system, eliminating the need for an expensive trip to the dealership for programming. You get a part that works correctly right out of the box, solving the root cause of the problem and restoring factory-spec fuel delivery for a dependable, long-term fix.
A Technician’s Notebook: The Intermittent Stall
A customer brought in his ’08 Silverado with a frustrating problem: it would run fine for days, then stall without warning at a stoplight. He’d already replaced the fuel filter and was about to spend big on a new in-tank fuel pump. No solid Check Engine codes were stored, just a history code for P069E (Fuel Pump Control Module Commanded On). Instead of throwing parts at it, we put it on the lift. The FPCM, located on the driver-side frame rail, showed tell-tale signs of water intrusion and corrosion on the casing. A quick voltage check confirmed it was failing intermittently. We installed a new, pre-programmed 2008-2009 Sierra Denali FPCM, and the truck has run flawlessly since. It’s a classic example of how diagnosing the control side first can save hundreds of dollars.
Is Your Truck Showing These Symptoms?
A failing FPCM can mimic a bad fuel pump. Watch for these common indicators before making a costly misdiagnosis:
- ✔ Engine cranks but won’t start
- ✔ Stalling, especially when coming to a stop or at idle
- ✔ Severe engine hesitation or sputtering under acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, P0230, or U0109 (Lost Communication With Fuel Pump Control Module)
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle in under an hour with basic hand tools. The module is typically located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FPCM on the vehicle’s frame. On most trucks and SUVs, it’s on the left (driver’s side) frame rail. On some vehicles like the Colorado or Traverse, its location may vary slightly.
- Disconnect Electrical Connectors: Carefully press the release tabs and unplug the two electrical connectors from the old module. Inspect the connectors for any corrosion or damage.
- Remove the Old Module: Use a socket wrench to remove the bolts securing the module to the frame. The old unit may be corroded, so a little penetrating oil can help.
- Install the New Module: Mount your new, pre-programmed FPCM onto the frame and tighten the bolts securely.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal. Your installation is complete, with no programming required!

Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is essential. We use it to flash the module with the correct, most recent GM software for your specific vehicle. This step ensures full compatibility and prevents performance issues, making the part truly plug-and-play.
What does the Fuel Pump Control Module (FPCM) do?
The FPCM acts as a smart relay for your fuel pump. Instead of just turning the pump on or off, it receives commands from the Engine Control Module (ECM) and precisely regulates the voltage sent to the fuel pump. This provides optimal fuel pressure across all driving conditions, improving efficiency and performance.
Is this part difficult to install myself?
Not at all for most people with basic tools. The module is typically mounted to the outside of the frame rail with just a few bolts and two electrical connectors. It’s one of the more accessible DIY repairs you can perform.
Will this fix a P069E code?
In the vast majority of cases, yes. Diagnostic Trouble Code P069E indicates a performance or communication issue with the Fuel Pump Control Module. A failed FPCM is the most common cause of this code on these GM vehicles.
Is this a new or used part?
This is a high-quality, new-condition module that has been professionally programmed to your vehicle’s specifications. It meets or exceeds original equipment standards for performance and longevity.
