Is your 2008-2009 Chevrolet Suburban 1500 suddenly stalling, hesitating, or refusing to start? These are frustrating and often dangerous symptoms of a failing Fuel Pump Control Module (FPCM). Don’t get stranded or pay expensive dealership programming fees. This is the direct-fit, reliable solution you need to restore your vehicle’s performance and your peace of mind. This module, also known as a Fuel System Control Module (FSCM), is the brain behind your fuel pump, and when it fails, it can mimic a bad fuel pump, leading to misdiagnosis and wasted money.
We take the guesswork and extra cost out of the repair. Unlike a part from the dealer, this FPCM arrives at your door pre-programmed with the latest GM software updates, specifically flashed to your vehicle’s VIN. This means no extra trip to a mechanic for costly programming. It’s a true plug-and-play solution designed for a hassle-free installation, whether you’re a seasoned technician or a DIY enthusiast.
From the Diagnostic Bay: The Ghost of a Bad Fuel Pump
I’ll never forget a 2008 Tahoe that came into my shop on a tow truck. The owner had just spent a fortune having a new fuel pump installed elsewhere, but the truck still wouldn’t start. He was convinced he got a faulty pump. After hooking up my scanner, I saw no communication with the fuel pump module (DTC U0109) and a code for fuel pump circuit failure (P069E). I went straight to the driver-side frame rail, and there it was: the FPCM, covered in white, chalky corrosion from years of exposure to road salt and moisture. The connectors were green with decay. We installed a new, pre-programmed 2008-2009 Suburban 1500 FPCM, and the truck fired up on the first try. It’s a classic failure on these GM trucks and SUVs, and catching it correctly saves customers hundreds.
Is Your Vehicle Showing These Signs of FPCM Failure?
A faulty FPCM can cause a range of issues that are often misdiagnosed. If you’re experiencing any of the following, this module is the likely culprit:
- ✔ Engine stalls unexpectedly, especially while driving.
- ✔ Vehicle cranks but refuses to start (no-start condition).
- ✔ Hesitation or stumbling during acceleration.
- ✔ “Reduced Engine Power” message on the dashboard.
- ✔ Check Engine Light with codes such as P069E, P0230, P0606, or U0109.
- ✔ A buzzing or whining noise from the fuel pump that is inconsistent.
A Straightforward Guide to Installation
Replacing the FPCM is a job most DIYers can handle in their driveway with basic tools. This pre-programmed module makes it even simpler.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most compatible trucks and SUVs like the Suburban or Tahoe, you will find the FPCM mounted to the driver-side frame rail, typically above the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the old module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new FPCM into the same location. Apply a small amount of dielectric grease to the connector pins to protect against future corrosion before plugging them in securely.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds (without starting) to allow the system to prime, then start your engine. The vehicle is ready to drive!

Frequently Asked Questions
What does this Fuel Pump Control Module do?
The FPCM regulates the voltage sent to your fuel pump. This ensures the pump delivers the precise amount of fuel the engine needs under all conditions, improving efficiency and performance. When it fails, it can starve the engine of fuel.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to flash the module with the exact software calibration specified by GM for your vehicle’s specific configuration. This ensures perfect compatibility and performance, eliminating the need for you to have it programmed.
Is this part difficult to install?
No, this is a very straightforward repair. The module is typically mounted on the vehicle’s frame rail and is held in place by a few bolts. Since we program it for you, it’s a simple plug-and-play process once you access it.
What happens if I install it without programming?
An unprogrammed module will not work correctly. The vehicle will likely not start, or it will run very poorly and set multiple trouble codes. Our pre-programming service solves this entire problem for you.
Is this a new or used part?
This is a high-quality, tested replacement part that is guaranteed to restore function. We load it with new, vehicle-specific GM software to ensure it performs reliably for years to come.
