Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?
If you’re experiencing frustrating engine performance issues with your 2008-2009 GMC Savana 1500 or other compatible GM vehicle, a faulty Fuel Pump Control Module (FPCM) is a very common culprit. This critical component, also known as a Fuel System Control Module (FSCM), is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded with a vehicle that cranks but won’t start, stalls unexpectedly, or displays a ‘Service StabiliTrak’ or ‘Engine Power is Reduced’ message on the dash. Don’t let a small electronic box disrupt your daily life or work schedule. This is the direct, reliable solution you need.
The Critical Role of the Fuel Pump Control Module
In modern GM vehicles, the FPCM is the brain behind the fuel delivery system. Unlike older systems that ran the fuel pump at full power all the time, the FPCM uses pulse-width modulation (PWM) to vary the fuel pump’s speed based on engine demand. It receives commands from the Engine Control Module (ECM) and adjusts fuel pressure accordingly. This sophisticated control provides better fuel efficiency, reduces emissions, and extends the life of the fuel pump. However, due to their typical mounting location on the frame rail, these modules are exposed to harsh conditions—road salt, water, mud, and vibrations—which often leads to internal corrosion and electronic failure.
From the Diagnostic Bay
I remember a 2008 Silverado 1500 that came in on a tow truck. The owner was convinced his new fuel pump was bad—he had just replaced it a week prior to solve a long-crank issue. The truck would crank all day but wouldn’t fire up. We scanned it and found a U0109 ‘Lost Communication with Fuel Pump Control Module’ code. A quick check at the module’s location on the driver’s side frame rail told the whole story. The aluminum housing was swollen and corroded, and the connector was full of green crust. The original FPCM had failed, causing the initial issue, and the new fuel pump was never the problem. We installed a new, pre-programmed FPCM, and the truck fired up on the first try. It’s a classic case of diagnosing the entire system, not just the most obvious part.
Diagnosing Your Failing 2008-2009 Savana 1500 Fuel Pump Module
A failing FPCM can mimic other fuel system problems, making diagnosis tricky. However, there are several key indicators that point directly to this module. If you’re experiencing any combination of the symptoms below, it’s highly likely your FPCM is the root cause. This module is a direct replacement and is pre-programmed to your vehicle’s VIN, ensuring a seamless and effective repair.
Common Symptoms of a Bad FPCM:
- ✔ Engine Cranks but Will Not Start: This is the most common symptom. The module fails to command the fuel pump on, resulting in no fuel pressure.
- ✔ Stalling While Driving: The module may fail intermittently, cutting power to the fuel pump and causing the engine to stall, often without warning.
- ✔ Hesitation or Stumbling on Acceleration: An erratic FPCM may not provide the necessary fuel pressure under load, causing poor engine performance.
- ✔ Check Engine Light: A malfunctioning module will almost always trigger a Check Engine Light with specific diagnostic trouble codes (DTCs).
- ✔ ‘Engine Power is Reduced’ Message: The vehicle’s computer may limit engine power to prevent damage when it detects a fault in the fuel system.
- ✔ Associated DTCs: Look for codes like P069E, P0230, P0606, or U0109, which directly point to a problem with the FPCM or its circuit.
The Plug-and-Play Programmed Solution
The biggest hurdle in replacing an FPCM has traditionally been the need for programming. A new module from a dealership must be installed and then programmed with a proprietary scan tool, like a GM MDI, to communicate with your vehicle’s other computers. This adds significant cost and inconvenience, requiring a trip to a dealer or a highly-equipped shop. Our solution eliminates this step entirely. When you purchase this module, you provide us with your vehicle’s VIN. We then flash the module with the latest, most stable GM-certified software specifically for your vehicle. The part you receive is ready for immediate installation—a true plug-and-play fix.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the primary benefit of our service. We program the module to your vehicle’s specific VIN before shipping it to you. This means it is ready for installation right out of the box, saving you time and the expense of dealer programming.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. Without your VIN, we cannot program the module, and it will not function in your vehicle. The order cannot be processed until the VIN is supplied. Please add your VIN in the notes at checkout or send us a message after your purchase.
Where is the FPCM located on my 2008 Savana 1500?
On most GM trucks and vans from this era, including the Savana 1500, the Fuel Pump Control Module is mounted to the driver’s side frame rail, typically near the spare tire. It’s exposed to the elements, which is a primary reason for its high failure rate.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward. It typically involves safely raising the vehicle, locating the old module on the frame, disconnecting the electrical connector, and removing a few bolts. The new module bolts in its place, the connector is reattached, and the job is done. Since it’s pre-programmed, no further steps are needed.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded On) is one of the most common codes indicating a failed FPCM. While you should always perform a complete diagnosis, replacing a faulty FPCM is the standard and effective repair for this code.
