Is Your Truck Stalling, Hesitating, or Refusing to Start?
If your 2008-2009 GMC Sierra Denali, or another compatible GM vehicle, is experiencing frustrating fuel delivery problems, a faulty Fuel Pump Control Module (FPCM) is a very likely 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 symptoms ranging from intermittent stalling and rough idling to a complete no-start condition. This isn’t just an inconvenience; it’s a critical failure that needs a reliable solution.
This replacement Fuel Pump Control Module, part number 13501024, is the definitive solution to restore your vehicle’s performance and reliability. Unlike generic modules that require an expensive trip to the dealership for programming, this unit arrives at your door pre-programmed specifically for your vehicle. We use your Vehicle Identification Number (VIN) to load the latest, most stable GM software, ensuring seamless communication with your truck’s powertrain control module (PCM) and perfect operational parameters right out of the box.
From the Diagnostic Bay
We had a 2008 Silverado 1500 towed in with a classic complaint: ‘It just died while I was driving and won’t restart.’ The customer had already replaced the fuel pump, thinking that was the obvious fix, but the problem persisted. A quick scan revealed a P069E trouble code: ‘Fuel Pump Control Module Commanded OFF.’ Instead of just throwing another part at it, we located the FPCM on the driver’s side frame rail. It was caked in mud and road salt, and the connector showed signs of corrosion. These modules live in a harsh environment, and their exposure to the elements is often their downfall. We installed a new, VIN-programmed module, cleared the codes, and the truck fired right up with perfect fuel pressure. This is a textbook failure we see often, and a pre-programmed module is the fastest, most effective fix.
Symptoms of a Failing Fuel Pump Control Module
- ✔ Engine Stalling: The engine may stall unexpectedly while driving or when coming to a stop, often without warning.
- ✔ No-Start Condition: The engine cranks but will not start due to a lack of fuel pressure.
- ✔ Hesitation or Stumbling: The vehicle may hesitate or stumble during acceleration as the module fails to command the correct fuel pump speed.
- ✔ Check Engine Light: A failing FPCM will often trigger diagnostic trouble codes (DTCs) such as P069E, P0230, P025A, or U0109.
- ✔ Rough Idle: Inconsistent fuel pressure can lead to a rough or erratic idle.
- ✔ Reduced Power: The vehicle may feel sluggish or underpowered, especially under load.
The Critical Role of the 2008-2009 Sierra Denali FPCM
Modern fuel systems are far more sophisticated than older, constant-pressure systems. The 2008-2009 Sierra Denali FPCM acts as a smart controller, using pulse-width modulation (PWM) to vary the fuel pump’s speed. At idle, it slows the pump down to save energy and reduce noise. During heavy acceleration, it commands full speed to deliver the necessary fuel volume. This precise control improves efficiency and extends the life of the fuel pump. When the module fails, this control is lost, leading directly to the symptoms you’re experiencing. Our module restores this factory-designed function with the benefit of the most recent software updates from GM, which often address the very issues that caused the original part to fail.
Plug-and-Play Installation, No Dealer Required
The single biggest advantage of this module is the VIN-specific programming we perform before shipping. This makes the installation process straightforward for a DIY mechanic or a professional technician. Simply locate the old module (typically on the driver-side frame rail), disconnect the battery, unplug the electrical connector, unbolt the old unit, and install the new one in its place. Once installed and the battery is reconnected, your vehicle is ready to go. You save hundreds of dollars in dealership programming fees and the time and hassle of getting your vehicle to a service center.
Wide Compatibility Across the GM Lineup
This module is a direct replacement for a wide range of GM trucks and SUVs. It is compatible with the following part numbers: 13501024, 15213110, 20759945, 20850907, 25785013, 25854536, 25866052, and 25967325. Please verify the fitment list to ensure it matches your specific vehicle. If you’re unsure, our team is here to help you confirm compatibility.
Frequently Asked Questions
Why does this module need my VIN to be programmed?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact software calibration specified by GM for your truck’s engine, transmission, and emissions equipment. This ensures the FPCM communicates correctly with the other computers on your vehicle and operates the fuel pump at the precise parameters for optimal performance and efficiency.
Is this part truly plug-and-play?
Yes. Because we program it to your VIN before it ships, no further programming or setup is required. Once you install it and reconnect your battery, the module is ready to function correctly. It is a direct-fit replacement for the original part.
Where is the FPCM located on my 2009 Sierra Denali?
On most GMT900 platform trucks and SUVs like the Sierra, Silverado, Tahoe, and Yukon, the Fuel Pump Control Module is mounted to the driver’s side frame rail, typically above the spare tire. It’s exposed to the elements, which is a primary reason for its high failure rate.
What happens if I install a module that isn’t programmed for my vehicle?
An unprogrammed or incorrectly programmed FPCM will likely result in a no-start condition. The vehicle’s security system and powertrain control module will not recognize it, and it will not be able to command the fuel pump to turn on. This is why our VIN-specific programming service is essential.
Can I be sure the FPCM is the problem and not my fuel pump?
While symptoms can overlap, a key indicator for FPCM failure is the presence of specific trouble codes like P069E (FPCM Commanded OFF) or U0109 (Lost Communication with FPCM). A technician can also test for voltage at the fuel pump connector while commanding the pump on with a scan tool. If there’s no voltage, the FPCM is the most likely culprit.
