Restore Your Truck’s Performance and Reliability
Is your 2008-2009 Avalanche 1500 suddenly stalling, hesitating on acceleration, or refusing to start? Before you condemn the fuel pump, the real culprit is often the Fuel Pump Control Module (FPCM), also known as a Fuel System Control Module (FSCM). In my 20+ years as a technician, I’ve seen countless vehicle owners and even other shops misdiagnose this issue, wasting time and money on unnecessary fuel pump replacements. This module, mounted on the frame rail, is exposed to road salt, water, and vibration, leading to internal corrosion and failure.
This isn’t just a replacement part; it’s a complete solution. We take a genuine GM module and pre-program it with the latest official software, specifically matched to your truck’s Vehicle Identification Number (VIN). This means you get a true plug-and-play fix without the expensive trip to the dealership for programming. You get improved reliability and restored engine performance, solving those frustrating fuel delivery problems for good.
From the Diagnostic Bay: The Ghost in the Machine
A customer brought in his ’08 Silverado with a classic complaint: it would crank but not start, but only intermittently. He’d already replaced the fuel pump himself, but the problem persisted. He was frustrated and out a few hundred dollars. I hooked up my scan tool and saw no communication with the fuel pump module and a pending P069E code. Instead of pulling the bed to check the pump he just installed, I went straight to the FPCM on the driver-side frame rail. The housing was corroded and the connector pins were green with decay. A new, pre-programmed FPCM had him back on the road in 15 minutes. It’s a textbook failure on these trucks, and knowing where to look first saves a world of headache.
Is Your Truck Showing These Telltale Signs?
A failing FPCM can mimic a bad fuel pump, but there are key symptoms to watch for. If you’re experiencing any of the following, this module is the most likely solution:
- âś” Sudden engine stalling, especially while driving
- âś” Vehicle cranks but refuses to start
- âś” Hesitation or sputtering under load or acceleration
- âś” Check Engine Light with codes like P069E, P0230, P0627, or U0109
- âś” Engine running in “Reduced Power” mode
- âś” An audible fuel pump that doesn’t prime when the key is turned
DIY Installation: A 20-Minute Fix
You don’t need to be a master mechanic to replace this module. With basic hand tools, you can have your truck running right in your own driveway. This simple installation saves you hundreds in shop labor costs.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most GM trucks and SUVs like the Avalanche, the FPCM is mounted to the driver-side frame rail, typically above the spare tire.
- Disconnect and Remove: Unplug the electrical connector. Be gentle, as the locking tab can be brittle. Then, remove the bolts holding the old module to the frame.
- Install the New Module: Bolt the new, pre-programmed FPCM into the same location. Apply a small amount of dielectric grease to the connector pins for added protection.
- Reconnect and Test: Plug the electrical connector firmly into the new module. Reconnect your battery terminal, turn the key to the ‘On’ position, and listen for the fuel pump to prime. Start your engine and enjoy a smooth, reliable ride.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for a simple, plug-and-play installation.
What information do you need from me?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN.
Where is the FPCM located on my 2008 Avalanche?
On the 2008-2009 Avalanche and similar GM trucks, the Fuel Pump Control Module is typically mounted on the inside of the driver-side frame rail, often near or above the spare tire.
Will this fix a Check Engine Light with code P069E?
Yes. P069E (Fuel Pump Control Module Requested MIL Illumination) is one of the most common diagnostic trouble codes indicating a failed FPCM. Replacing the module with this pre-programmed unit is the correct fix.
Is this the same as the fuel pump?
No. The fuel pump is located inside your fuel tank. This is the separate electronic control module that regulates the voltage and pressure delivered to that pump. It’s a common point of failure.
