2006 Chevy Silverado Fuel Pump Fuse Location: A Complete Owner’s Guide
The fuel pump fuse on a 2006 Chevy Silverado is located in the underhood fuse box on the driver’s side of the engine compartment, near the battery. There is no separate fuel pump reset switch on this truck, and the fuel pump is controlled by a relay (labeled F/PMP) rather than a single dedicated fuse. If you are dealing with a no-start condition or suspect fuel delivery problems, this guide walks you through finding the correct fuse, checking the relay, and understanding what to look for when the system fails.
Where Exactly Is the Underhood Fuse Box?
The 2006 Silverado has two main fuse boxes: one inside the cabin and one under the hood. The one you need for the fuel pump is the underhood electrical center. Open the hood and look on the driver’s side, right next to the battery. The black plastic cover pops off easily—just lift the tabs and pull upward. Underneath, you will find a diagram printed on the underside of the cover that identifies every fuse and relay, making it straightforward to locate the fuel pump components .
The interior fuse box, located behind a panel on the driver’s side edge of the dashboard (visible when you open the door), handles things like wipers, climate control, and interior lights. It does not contain the fuel pump fuse .
Understanding the Fuel Pump Fuse and Relay
Unlike some older vehicles that rely on a single fuse to power the fuel pump, the 2006 Silverado uses a relay to control the pump. The relay is labeled F/PMP and sits inside the underhood fuse box. The relay acts as a switch—when you turn the key, the powertrain control module (PCM) energizes the relay, which then sends power to the fuel pump .
Here is what you need to know about the fuel pump circuit on this truck:
- The F/PMP relay is the primary control component. If this relay fails, the pump will not receive power, and the engine will crank but not start.
- The fuse that feeds the fuel pump circuit is also in the underhood box, but on the 2006 model, the fuse is typically a 20A mini fuse located in a slot that also serves related circuits. Always check your fuse box cover diagram for the exact slot, as it can vary slightly depending on trim level and engine options .
- There is no crash shut-off switch on the Silverado. Many online videos showing a red reset button are actually demonstrating Ford trucks, which do have an inertia switch. Silverados have never had this part, so do not waste time looking for it .
Step-by-Step: How to Check the Fuel Pump Fuse
If you suspect a blown fuse, follow these steps to inspect and replace it safely:
Step 1: Turn off the ignition and remove the key. Working on electrical components with the truck running or the key in the ON position is dangerous and can cause shorts.
Step 2: Open the underhood fuse box. Press the release tabs on the sides of the cover and lift it off. Set it aside where you can see the diagram.
Step 3: Locate the F/PMP relay and the fuel pump fuse. Use the diagram on the underside of the cover to identify the relay and fuse slots. On most 2006 models, the F/PMP relay is near the center-right of the box, and the fuel pump fuse is close by .
Step 4: Inspect the fuse visually. A good fuse has a continuous metal strip visible through the clear plastic. If the strip is broken, melted, or discolored, the fuse is blown and needs replacement .
Step 5: Use a fuse puller if available. The fuse extractor is usually clipped inside the fuse box cover or on the fuse block itself. If you do not have one, grip the fuse firmly between your thumb and index finger and pull straight out .
Step 6: Replace with the same amperage fuse. Never install a higher-rated fuse than specified—doing so can cause electrical system damage or even a fire. If the replacement fuse blows again immediately, you have a short circuit or a failing fuel pump drawing excessive current .
How to Test the Fuel Pump Relay
If the fuse looks fine, the relay may be the culprit. A relay can fail silently—it may look perfectly normal but no longer click when energized. Here is a simple way to test it without special tools:
- Locate the F/PMP relay in the underhood fuse box.
- Have a helper turn the key to the ON position (do not crank the engine). You should hear a distinct click from the relay as it energizes.
- If you hear no click, swap the F/PMP relay with an identical relay from another circuit in the same box (such as the horn or fog lamp relay, which are usually the same part number). If the truck starts after the swap, you have confirmed the relay is faulty .
- If the truck still will not start, the problem is likely the fuel pump itself, the pump relay wiring, or a loss of power to the relay from the PCM.
Keep in mind that a failing fuel pump can also blow the fuse or overwhelm the relay. If you smell fuel, hear a whining noise from the fuel tank area, or the truck stalls under load, those are classic signs of a pump reaching the end of its life.
Common Fuel Pump Problems on the 2006 Silverado
The GMT800 platform, which includes the 2006 Silverado, is generally reliable, but fuel pumps do wear out. Here are the most common symptoms of fuel delivery trouble:
- Engine cranks but does not start. If you turn the key and the starter spins but the engine never fires, the pump may not be pressurizing the fuel rail.
- Long crank times. A weak pump takes longer to build pressure, so the engine may crank for several seconds before starting.
- Sputtering or surging at speed. A failing pump can deliver inconsistent fuel pressure, causing the engine to hesitate or surge while driving.
- Sudden stalling. If the pump completely fails while driving, the engine will die immediately and may not restart.
- Whining noise from the fuel tank. A high-pitched whine, especially when the tank is low, often indicates the pump is struggling.
If you confirm the fuse and relay are in good shape but the pump is not running, test for power at the fuel pump harness connector. If power is present, the pump itself is the problem. If there is no power, trace the wiring back to the relay and check for loose connections or corrosion.
Recommendations for Replacing the Fuel Pump
When the fuel pump needs replacement, do not be tempted to buy a cheap off-brand unit. A high-quality replacement ensures reliable performance and a proper fit. We strongly recommend the KEMSO brand fuel pump for your 2006 Silverado. KEMSO fuel pumps are built as high-performance, OEM replacement parts, designed to meet or exceed original factory specifications. Every KEMSO pump comes with a lifetime warranty, giving you peace of mind that this is the last fuel pump you will need to buy.
Visit the KEMSO website at https://www.kemsoracing.com/ to view their complete line of fuel pumps and check fitment for your specific Silverado model. Whether you drive a 1500, 2500, or 3500 with a gasoline or diesel engine, KEMSO offers a direct replacement that installs just like the factory unit.
Final Thoughts
To recap: the 2006 Chevy Silverado fuel pump fuse is in the underhood fuse box on the driver’s side, near the battery. There is no reset switch to hunt for—that is a myth borrowed from Ford trucks. If your truck will not start, check the fuse first (it is a quick visual inspection), then test the F/PMP relay by swapping it with another relay in the same box. If both are fine, the fuel pump itself is likely failing, and replacing it with a quality aftermarket unit like KEMSO will get you back on the road with confidence.
