2007 GMC Yukon Fuel Pump Control Module Location: Where It Is and How to Access It
The bottom line up front: On a 2007 GMC Yukon, the fuel pump control module is mounted on the outside of the fuel tank, on the driver’s side, just forward of the rear axle. You do not need to drop the fuel tank to reach it, but you do need to safely raise the vehicle and, in some cases, remove a protective shield to get a clear view. This module is a common failure point on 2007–2009 GM trucks and SUVs, and knowing exactly where it sits can save you hours of guesswork and avoid an unnecessary trip to a repair shop.
The 2007 GMC Yukon, along with its siblings the Chevrolet Tahoe and Cadillac Escalade, uses a separate electronic module to control fuel pump speed and pressure. This is not the fuel pump itself. The pump stays inside the fuel tank, while the control module lives outside, bolted to the tank’s exterior. This design allows the module to be replaced without draining or removing the tank, which is good news for DIY owners. In this guide, you will learn the exact location, how to access it safely, the symptoms of a failing module, and what replacement parts you should consider.
What Is the Fuel Pump Control Module and Why Does It Fail?
The fuel pump control module (FPCM) is a small electronic box that regulates voltage to the in-tank fuel pump. It adjusts fuel delivery based on demand, helping the engine run smoothly under different loads. When it fails, the fuel pump may stop receiving power entirely, or it may run at full speed all the time, which can cause fuel pressure problems.
On the 2007 Yukon, this module is part of a broader fuel delivery system that includes the pump, the fuel level sensor, and the wiring that connects them. The module is particularly prone to failure because it is exposed to road moisture, salt, and temperature extremes. Water can seep into the connector, causing corrosion and intermittent electrical faults. Over time, the internal circuitry can also overheat, leading to a complete shutdown. This is why so many owners report stalling and no-start conditions after a few years of ownership.
If the module fails, the engine may crank but not start. You might also notice the check engine light with a diagnostic trouble code like U0109, which means lost communication with the fuel pump control module. In some cases, the engine starts fine when cold but stalls after the vehicle warms up, because heat causes the failing module to lose connection.
Exact 2007 GMC Yukon Fuel Pump Control Module Location
Here is the straightforward answer: the fuel pump control module is attached to the driver’s side of the fuel tank, roughly in line with the front edge of the rear wheel well. It is mounted on a bracket that clamps to the tank shell, and it sits low enough that you can see it from underneath the truck.
To be more specific:
1. Position relative to the vehicle: The module is located above the spare tire area, forward of the rear axle. If you crawl under the rear of the Yukon and look up toward the driver’s side, you will see the fuel tank. The module is a small black plastic or metal box with a wiring harness plugging into it. It is not inside the tank; it is bolted to the outside of the tank.
2. What it looks like: The module is roughly the size of a paperback book. It has a single electrical connector with several wires. A metal bracket holds it in place. On some models, there is also a plastic cover or a heat shield that must be removed to access the connector.
3. How to find it without a lift: If you do not have access to a lift, you can still reach the module by safely raising the rear of the vehicle with jack stands. Once the truck is elevated, lie down behind the rear axle and look upward. You may need a flashlight to spot the module. It is easier to see if you remove the spare tire and its carrier first, as the tire can block your line of sight.
4. Which side of the tank: The module is not centered. On the 2007 Yukon, it is offset to the driver’s side. This is true for both the standard wheelbase and the XL models, and it also applies to the Denali trim. If you are looking at the truck from the rear, the module is on the left-hand side.
5. Is it the same for 2007 and 2008–2009? Yes, the general location is the same for 2007, 2008, and 2009 model years. However, the part numbers differ. For 2007, the original GM part number is 19332069. For 2008–2009, the part numbers include 13501024, 20759945, and 25785013, depending on the vehicle’s build date and whether it is a Yukon or Yukon XL. If you are replacing the module, make sure you order the correct part for your specific model year.
Tools and Safety Precautions Before You Start
Working under a 5,000-pound SUV is not something to take lightly. Before you even think about touching the module, you need to prepare.
1. Safety first: Park on a flat, solid surface. Engage the parking brake and chock the front wheels. Use a high-quality floor jack and a pair of heavy-duty jack stands. Never rely on the jack alone to hold the vehicle up. The Yukon is heavy, and a jack failure can cause serious injury or death.
2. Let the truck cool down: The fuel system operates under pressure, and the metal components around the tank can be hot after driving. Wait at least an hour after the engine has been running before you start working. This reduces the risk of burns and makes handling the wiring harness easier.
3. Have the right tools: You will need a socket set with metric and standard sizes, a flathead screwdriver, a trim removal tool, and a flashlight. The module is held by one or two bolts, and the electrical connector has a locking tab. You may also need a swivel socket if the bolts are hard to reach.
4. Consider disconnecting the battery: Fuel system components are electrical. To prevent any accidental sparks while you are near the tank, disconnect the negative battery cable before you begin. This is especially important if you plan to unplug the module or work near the fuel lines.
5. Remove the spare tire: On many Yukon models, the spare tire hangs directly beneath the rear cargo area, right in the path of the module. Lowering and removing the spare tire gives you much better access. It also makes the module easier to see and reach.
How to Access and Replace the Module Step by Step
Once you have the truck safely raised and the spare tire out of the way, the replacement process is straightforward. Here is the step-by-step procedure that most DIY owners follow:
1. Identify the module. Look for a small box bolted to the driver’s side of the fuel tank. It will have a wiring harness connected to it. Clean the area around the module with a shop rag to remove dirt and grime before you start unplugging anything. This prevents debris from falling into the connector.
2. Remove the protective cover (if equipped). Some 2007 Yukon models have a plastic skid plate or heat shield that covers the module. This shield is usually held on by a few 10mm bolts. Remove it and set it aside. You may need a swivel socket to reach the rear bolts.
3. Disconnect the electrical connector. Press the locking tab on the connector and pull it straight off the module. Do not yank on the wires. If the connector is stuck, use a small flathead screwdriver to gently pry the tab. Inspect the connector for signs of corrosion or burned pins. This is a common failure point, and if the pins look damaged, replacing the module alone may not fix the problem.
4. Remove the mounting bolts. The module is held by either two bolts or a single bracket. Use a socket wrench to remove them. Keep the bolts in a safe place, as you will reuse them for the new module.
5. Pull the module off the bracket. The module may have a rubber gasket or foam pad behind it. Take note of how it sits before removing it. You will need to install the new module in the same orientation.
6. Compare the old and new modules. Before you install the new module, compare it side by side with the old one. Check that the connector shape, mounting holes, and overall dimensions match. Do not force a different part number into place.
7. Install the new module. Position the new module on the bracket and insert the mounting bolts. Tighten them snugly, but do not overtighten. Reconnect the electrical connector until you feel the locking tab click into place. Reinstall the protective cover if you removed one.
8. Reconnect the battery and test. Start the engine and let it idle. Check that the fuel pump primes when you turn the key to the ON position. If the engine starts and runs smoothly, you are done. If you still have a no-start condition, you may have a wiring issue that requires further diagnosis.
Symptoms That Point to a Failing Fuel Pump Control Module
Knowing the symptoms before the module fails completely can save you from being stranded. Here are the most common signs that the fuel pump control module on your 2007 Yukon is going bad:
1. Engine cranks but will not start: This is the most obvious symptom. When the module dies, it stops sending power to the fuel pump. The engine will crank indefinitely but never fire up.
2. Stalling while driving: The module may work intermittently. You could be driving down the highway and suddenly lose power as the fuel pump cuts out. The engine may stall and then restart after a few minutes once the module cools down.
3. Long cranking before starting: If the module is weak, the fuel pump may not build pressure quickly enough. This causes extended cranking before the engine catches.
4. Diagnostic trouble code U0109: If you scan the OBD-II system and see U0109, it means the engine control module has lost communication with the fuel pump control module. This code almost always points to a failed module, a wiring problem, or a bad connection.
5. Low fuel pressure: If you have a fuel pressure gauge, you may see pressure below the specified range. This happens when the module limits power to the pump, preventing it from running at full capacity.
6. Whining noise from the fuel tank: A failing module can cause the fuel pump to run erratically, producing a loud whining or buzzing sound from the tank area.
If you notice any of these symptoms, do not delay. Driving with a failing fuel pump control module can leave you stranded and may also damage the fuel pump itself, turning a $150 repair into a $800 job.
Buying the Right Replacement: Original GM vs. Aftermarket
When it comes time to buy a replacement fuel pump control module, you have two main options: OEM (original equipment manufacturer) parts from GM, or aftermarket alternatives. Each has its pros and cons, and the right choice depends on your budget and how long you plan to keep the truck.
1. GM OEM parts: The original GM module is the safest choice if you want a guaranteed fit. For the 2007 Yukon, the GM part number is 19332069. For later models, GM also lists 13501024 and 20759945. OEM parts are built to the exact specifications of your truck, so you do not need to worry about compatibility. The downside is price; GM modules can cost between $150 and $300, depending on where you buy them.
2. Aftermarket modules: Several brands make drop-in replacements for the GM module. These are often cheaper, but quality varies. Some aftermarket modules are little more than knock-offs with poor internal components, and they fail quickly. If you go this route, stick to well-known brands with a track record of reliability.
3. What to look for: Regardless of brand, make sure the module you buy is specifically designed for the 2007 GMC Yukon. Check the part number compatibility before ordering. Also, buy from a seller with a good return policy in case the part does not fit or fails early.
4. Should you replace the fuel pump too? If your Yukon has high mileage (over 150,000 miles) and you are already working on the fuel system, it may be wise to replace the fuel pump as well. The pump and the module work together, and if the module failed due to a wiring short, the pump might have been damaged too.

Additional Tips for Long-Term Reliability
Once you have replaced the fuel pump control module, there are a few things you can do to extend the life of the new part and avoid a repeat failure next year.
1. Keep the connector clean: Corrosion in the electrical connector is the leading cause of module failure. Apply dielectric grease to the connector pins before plugging it in. This creates a moisture barrier and prevents future corrosion.
2. Inspect the wiring harness: Look for chafed, melted, or broken wires near the module. The harness routes along the frame and can rub against sharp edges over time. Repair any damaged wires before they cause another short.
3. Secure the module properly: Make sure the mounting bolts are tight and the module does not rattle. Vibration can loosen the internal solder joints over time.
4. Consider a fuel system cleaning: If the fuel pump has been running at reduced speed due to a failing module, carbon and varnish may have built up in the fuel lines. A quality fuel system cleaner can help remove these deposits and keep the new module and pump working efficiently.
5. Address check engine lights promptly: If you see a dashboard warning light, do not ignore it. Scan the codes early. A small electrical issue is much cheaper to fix than a fully stalled fuel system.
Final Thoughts
The 2007 GMC Yukon fuel pump control module location is one of the most practical things you can learn about your vehicle.
