Is Your GM Truck or SUV Stalling or Failing to Start? The FPCM is a Common Culprit.
If you’re experiencing frustrating issues like your 2008-2009 Sierra Denali, Silverado, Tahoe, or other compatible GM vehicle cranking but not starting, stalling unexpectedly, or showing a “Service Fuel System” message, a faulty Fuel Pump Control Module (FPCM) is a very likely cause. 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 by either starving the engine of fuel or cutting it off completely.
This isn’t just a simple relay; it’s a sophisticated electronic module that adjusts fuel flow based on engine load, speed, and other parameters. Over time, exposure to heat, moisture, and road vibrations—especially given its typical mounting location on the frame rail—can lead to internal electronic failure, causing a host of drivability problems.
From the Diagnostic Bay
We had a 2008 Silverado 1500 come into the shop on a tow truck. The owner was frustrated because he had just replaced the in-tank fuel pump himself, but the truck still wouldn’t start. It would crank all day long, but never fire. He was convinced he got a bad pump. We hooked up our diagnostic scanner and monitored the fuel system data. The key finding was that the Engine Control Module (ECM) was commanding 100% fuel pump duty cycle, but the FPCM was reporting 0% actual duty cycle and zero fuel rail pressure. The module was receiving the command but wasn’t executing it. We swapped in a new, pre-programmed FPCM, and the truck fired up on the first try. This is a classic case where the module, not the pump, was the root cause, saving the customer from buying another unnecessary part.
Symptoms of a Failing Fuel Pump Control Module
- âś” Engine Cranks but Won’t Start: The most common symptom, where the FPCM fails to activate the fuel pump at all.
- âś” Sudden Stalling: The engine may die while driving, sometimes without warning, especially under load or when coming to a stop.
- âś” Hesitation and Sputtering: Inconsistent fuel delivery can cause the vehicle to hesitate or sputter during acceleration.
- âś” Reduced Engine Power: The vehicle may feel sluggish and lack its normal power due to insufficient fuel pressure.
- âś” Check Engine Light: Fault codes related to the fuel pump circuit, such as P069E, P0230, or P025A, are often triggered.
- âś” “Service Fuel System” Message: The driver information center may display a warning message.

Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. The main benefit of our service is that we program the module to your specific vehicle using your VIN before we ship it. It arrives ready for installation, saving you time and money.
Where is the FPCM located on my vehicle?
On most GM trucks and SUVs from this era (like the Silverado, Sierra, Tahoe, Yukon, Escalade), the module is mounted to the driver’s side frame rail, typically near the spare tire.
Is this the same as a Fuel Pump Driver Module (FPDM)?
Yes, the terms Fuel Pump Control Module (FPCM), Fuel System Control Module (FSCM), and Fuel Pump Driver Module (FPDM) are often used interchangeably for this part.
What happens if I forget to provide my VIN?
We cannot ship the module without your VIN, as the programming is essential for it to function in your vehicle. We will contact you via email after your purchase to request the VIN if it was not provided during checkout.
Will this fix a P069E trouble code?
Yes, the DTC P069E (Fuel Pump Control Module Commanded OFF) is a very strong indicator that the FPCM itself has failed. Replacing it with this pre-programmed unit is the correct repair for that code.
