Restore Your Suburban’s Performance and Reliability
Is your 2013-2014 Suburban 1500 suddenly stalling, hesitating, or refusing to start? Before you condemn the fuel pump, the problem is often the brain behind the operation: the Fuel Pump Control Module (FPCM). As a technician with over two decades of experience, I’ve seen countless GM trucks and SUVs sidelined by a faulty FPCM. This module, also known as a Fuel System Control Module (FSCM), is critical for regulating the voltage sent to your fuel pump. When it fails, it starves your engine of the fuel it needs, leading to frustrating and potentially unsafe driving conditions.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra cost out of the repair by pre-programming this module to your vehicle’s specific VIN with the latest GM software updates. This means you can skip the expensive trip to the dealership for programming. Just install it, and you’re ready to go. It’s the most efficient way to get your truck back to factory-spec operation.
A Technician’s Notebook: The Misleading P069E Code
I once had a 2014 Tahoe in the bay with a persistent Check Engine Light and intermittent stalling at red lights. The owner had already replaced the fuel pump himself, but the problem remained. The only code was a P069E, which points to an issue in the FPCM circuit. After checking the wiring for corrosion—a common issue since these are mounted on the frame rail—I found it was clean. The culprit was the original FPCM itself. Internal corrosion and heat cycling had caused it to fail intermittently. Installing a new, pre-programmed module solved the problem instantly. This highlights why diagnosing the entire system, not just the most obvious part, is key to an effective repair.
Common Signs of a Failing FPCM
If your vehicle is exhibiting any of these symptoms, a failing Fuel Pump Control Module is a likely cause. A faulty module can also trigger specific Diagnostic Trouble Codes (DTCs) that a code reader can identify.
- âś” Engine cranks but will not start
- âś” Stalling, especially under load or when coming to a stop
- âś” Rough idle or engine hesitation during acceleration
- âś” Reduced engine power and poor fuel economy
- âś” Check Engine Light with codes such as P069E, P2635, or U0109
A Straightforward Guide to Your 2013-2014 Suburban FPCM Installation
Installing your new FPCM is a manageable job for a DIYer with basic tools. On the Suburban, Tahoe, and similar GM trucks, it’s typically located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Find the old FPCM mounted to the frame rail. It’s a small black box with electrical connectors. You may need to lower the spare tire for better access.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note their orientation. Then, unbolt the module from the frame. These bolts can sometimes be rusty, so a little penetrating oil can help.
- Install the New Module: Bolt the new, pre-programmed FPCM into the same location. Ensure it is securely fastened to the frame.
- Reconnect Everything: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the system to prime, then start the engine. Your vehicle should now run smoothly.

Frequently Asked Questions
Do I need to get this part programmed at the dealer?
No. We program the module to your vehicle’s VIN before we ship it. It arrives ready for installation, saving you time and money.
What information do you need from me?
After you place your order, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we have this information to program it correctly.
Where is this module located on my 2014 Suburban?
On the 2013-2014 Suburban 1500, the FPCM is typically mounted on the inside of the driver-side frame rail, often near the spare tire.
Is this the same as a fuel pump driver module?
Yes, Fuel Pump Control Module (FPCM), Fuel System Control Module (FSCM), and Fuel Pump Driver Module (FPDM) are different names for the same component that controls the fuel pump.
Will this fix a P069E code?
A faulty FPCM is a very common cause of a P069E code. While you should always verify wiring and connections, replacing a bad module with this pre-programmed unit is often the correct fix.
