Programmed GM Fuel Pump Control Module FPCM 25854536 | 2008-2009 Silverado Sierra

Is Your GM Truck or SUV Stalling, Hesitating, or Refusing to Start?

As a mechanic with over two decades of experience, I’ve seen countless GM vehicles towed into the shop with fuel delivery problems. The owner is often convinced they need a new, expensive in-tank fuel pump. More often than not, the real culprit is a much simpler, more accessible part: the Fuel Pump Control Module (FPCM), also known as the Fuel System Control Module (FSCM). If your 2008-2009 Silverado, Tahoe, Yukon, or other GM model is giving you trouble, this pre-programmed module is your direct-fit, reliable solution.

The Real Problem: Why Your Original FPCM Fails

On most of these trucks and SUVs, the factory FPCM is mounted on the frame rail, exposed to everything the road throws at it—water, salt, mud, and constant vibration. Over time, this leads to corrosion on the circuit board and connectors, causing erratic performance or complete failure. This module is the brain that tells your fuel pump how much pressure to deliver. When it fails, you get symptoms that are easily mistaken for a bad pump.

Why is a Pre-Programmed GM Fuel Pump Control Module the Smart Choice?

Buying a module from the dealer means you get a blank box. You then have to pay them an additional one or two hours of labor to program it to your vehicle’s Vehicle Identification Number (VIN). Our solution eliminates that entire step. We flash this module with the latest, most stable GM-approved software specifically for your VIN before we ship it. It arrives at your door ready for a simple, plug-and-play installation.

Common Symptoms of a Failing FPCM:

• ✔ Engine cranks but won’t start
• ✔ Stalling or sputtering, especially during acceleration
• ✔ Long crank times before the engine turns over
• ✔ “Reduced Engine Power” message on the dash
• ✔ Check Engine Light with codes like P069E, P0230, or U0109
• ✔ Inconsistent fuel pressure readings

Plug-and-Play Installation: No Dealer Visit Required

You can get your vehicle back on the road in under an hour with basic hand tools. Here’s a general guide for most truck and SUV applications:

1. Safety First: Disconnect the negative terminal from your vehicle’s battery.
2. Locate the Module: On most trucks and large SUVs (Silverado, Sierra, Tahoe, etc.), the FPCM is bolted to the driver’s side frame rail, often near the spare tire. On other models (like the Traverse or Colorado), it may be on a rear crossmember.
3. Disconnect and Remove: Carefully unplug the electrical connectors. Use a small screwdriver to release the locking tabs if needed. Then, unbolt the old module from the frame.
4. Install the New Module: Bolt your new, pre-programmed FPCM into the same location. For extra protection against future corrosion, I recommend applying a thin layer of dielectric grease to the connector pins before plugging them in.
5. Reconnect and Start: Reconnect the electrical harnesses and your battery terminal. The vehicle should now start and run smoothly with restored fuel pressure.

Frequently Asked Questions (FAQ) about the GM Fuel Pump Control Module

Q: How do I know if my FPCM is bad and not the fuel pump?

A: While symptoms overlap, a key indicator is the U0109 trouble code, which points directly to a communication loss with the FPCM. You can also check for power at the fuel pump connector while a helper cranks the engine; no power often means the FPCM isn’t sending the signal.

Q: What information do you need from me?

A: After you place your order, you must provide us with your 17-digit VIN. This is crucial for us to load the correct GM software for your vehicle’s specific configuration.

Q: Is this a difficult part to replace for a DIYer?

A: Not at all. The physical replacement is very straightforward, typically involving just a couple of bolts and electrical plugs. Since we handle the programming, you avoid the most complex part of the job.

Q: Will this module fix a P069E code?

A: Yes, the P069E code (Fuel Pump Control Module Requested MIL Illumination) is one of the most common codes indicating a faulty FPCM. This module is the direct solution for that issue.

Q: This part replaces multiple part numbers. Is it truly compatible?

A: Absolutely. This module is a direct replacement for several older part numbers, including 13501024, 15213110, 20759945, and others listed below. It contains the updated hardware and software to reliably replace all previous versions.
