2010 Chevy Traverse Fuel Pump Fuse Location: A Complete Owner's Guide
The fuel pump fuse on a 2010 Chevy Traverse is located in the underhood fuse block, which sits in the engine compartment on the passenger side of the vehicle. More specifically, the fuse labeled "FSCM" (Fuel System Control Module) with a 25A rating is the primary fuse that protects the fuel pump circuit, and it is positioned in slot F34 within that fuse box. There is also a 20A fuse labeled "FUEL PUMP" that protects the fuel pump and sender assembly directly. When the fuel pump stops working, checking these two fuses first can save you time and money before you start replacing expensive parts.
The 2010 Chevrolet Traverse, part of the first generation (GMT561) produced from 2009 to 2017, has two main fuse boxes. Understanding where they are and what each fuse does is essential for any owner who wants to troubleshoot electrical problems at home. This guide walks you through the exact locations, fuse assignments, and step-by-step testing procedures so you can get your Traverse running again with confidence.
Where Are the Fuse Boxes on a 2010 Chevy Traverse?
Before you can check the fuel pump fuse, you need to know exactly where the fuse boxes are located. The 2010 Traverse has two primary fuse panels:
1. Engine Compartment Fuse Block (Underhood Fuse Box)
This is the box you need for the fuel pump fuse. It is located in the engine compartment, on the passenger side of the vehicle, near the battery. Open the hood and look toward the passenger side, close to the firewall. The black plastic cover lifts off easily once you release the latches. This box houses the high-amperage fuses and relays that control major systems like the engine, cooling fans, starter, and fuel pump.
2. Instrument Panel Fuse Block (Passenger Compartment Fuse Box)
This fuse block is located under the instrument panel on the passenger side of the vehicle. You may need to remove the glove compartment or pull down a small cover panel to access it. This box contains fuses for interior components such as the radio, airbags, door locks, climate control display, and power seats.
Some sources also mention that the interior fuse box can be found on the driver's side of the dashboard near the door frame. This discrepancy likely comes from differences in how different trims and model years are configured. If you cannot find the fuse box under the passenger side dash, check the driver's side end of the dashboard as well.
Which Fuse Controls the Fuel Pump on a 2010 Chevy Traverse?
There are actually two fuses you need to know about when dealing with fuel pump issues on the 2010 Traverse:
1. FSCM Fuse (Slot F34, 25A)
The FSCM fuse protects the Fuel System Control Module, which manages the variable-speed fuel pump. This is the most important fuse for the fuel pump circuit. If this fuse blows, the fuel pump will not receive power at all.
2. FUEL PUMP Fuse (20A)
The FUEL PUMP fuse is a 20A fuse that protects the fuel pump and sender assembly directly. This fuse sits in the underhood fuse block as well. On the 2010 Traverse, the FUEL PUMP fuse is listed under a separate label in some diagrams, while the FSCM fuse handles the flow control module.
In addition to these fuses, the fuel pump relay is also located in the underhood fuse block. The relay is what actually switches power on and off to the fuel pump. If the relay fails, the pump will not run even with good fuses. Testing the relay is covered later in this guide.
Step-by-Step: Locating the Fuel Pump Fuse
Here is how to find the fuel pump fuse on your 2010 Chevy Traverse in under five minutes:
1. Open the hood and secure it properly.
Make sure the hood is fully open and the prop rod is engaged. You need both hands free to work on the fuse box.
2. Find the underhood fuse block.
Look on the passenger side of the engine compartment, near the battery and the firewall. The cover is a black plastic box with a latch or two. Some models may have a small diagram printed on the top of the cover that shows fuse positions.
3. Remove the fuse box cover.
Press the release tabs on the sides of the cover and lift it straight up. Set the cover aside carefully. On the underside of the cover, there is often a diagram that lists fuse positions and amperages. This is your quick reference for identifying the fuel pump fuse.
4. Locate fuse F34 (FSCM).
Using the diagram on the cover or the information from this guide, find the slot labeled FSCM or Fuel System Control Module. On the 2010 Traverse, this is a 25A fuse located in position F34 in the engine compartment fuse block. It is a mini blade-style fuse.
5. Locate the FUEL PUMP fuse (20A).
Look for the fuse labeled "FUEL PUMP" with a 20A rating. Depending on the exact build of your vehicle, this fuse may be positioned near the FSCM fuse or in an adjacent slot. The underhood fuse block on the 2010 Traverse has over 60 fuse positions, so using the diagram is the quickest way to find it.
6. Inspect the fuses visually.
Once you have located both fuses, pull them out using the fuse puller tool stored in the fuse box (usually a small plastic clip) or a pair of needle-nose pliers. Look through the transparent body of the fuse. If you see a broken or melted metal filament inside, or any dark discoloration, the fuse is blown and needs replacement.
How to Test the Fuel Pump Fuse
Visual inspection alone is not always enough. Sometimes a fuse looks fine but is actually cracked internally. Testing the fuse takes about two minutes with a multimeter.
1. Set your multimeter to the continuity test mode or the ohms setting.
If you do not have a multimeter, you can use a simple 12V test light, but a multimeter is more accurate.
2. Touch one probe to each of the two metal terminals on top of the fuse.
On a mini blade fuse, there are two small metal prongs sticking out from the top. Touch one test lead to each prong. If the multimeter beeps or shows near-zero resistance, the fuse is good. If it shows infinite resistance or no continuity, the fuse is blown.
3. Replace the fuse with the same amperage rating.
Never replace a blown fuse with one of a higher amperage. That can overload the wiring and cause serious damage, including fire. Always use the same rating: 25A for the FSCM fuse and 20A for the FUEL PUMP fuse.
4. Test again after replacement.
If the new fuse blows immediately when you turn the key, you have a short circuit or a failing fuel pump that draws too much current. Do not keep replacing fuses without finding the root cause.
How to Test the Fuel Pump Relay
If both fuses are good but the fuel pump still does not run, the next component to check is the fuel pump relay. The relay is a small black or gray cube located in the underhood fuse block.
1. Identify the relay.
Look for a relay labeled "FUEL PUMP" or "PWR/TRN" in the fuse box diagrams. On the 2010 Traverse, the powertrain relay (PWR/TRN) is commonly associated with fuel pump control.
2. Swap the relay with a known good one.
The simplest test is to swap the suspected fuel pump relay with another relay of the same type in the same fuse box. For example, you can swap it with the horn relay. If the fuel pump starts working after the swap, the original relay is faulty.
3. Use a multimeter for a more precise test.
With the relay removed, check for continuity between the relay coil terminals and for proper contact switching when power is applied. This is more advanced but gives a definitive answer.
Common Symptoms of a Blown Fuel Pump Fuse
How do you know if the fuse is actually the problem? These symptoms point directly to a fuel pump fuse or relay issue:
1. Engine cranks but will not start.
If the starter turns the engine over normally but the engine never fires up, the fuel pump may not be delivering fuel. This is the most common symptom.
2. No fuel pump hum.
Turn the ignition key to the ON position without starting the engine. You should hear a brief humming or whirring sound coming from the rear of the vehicle, near the fuel tank. This is the fuel pump priming. If you hear nothing, the pump is not receiving power.
3. Vehicle stalls while driving.
If the engine suddenly shuts off while driving and will not restart, a blown fuse or faulty relay could have cut power to the fuel pump mid-drive.
4. No fuel pressure at the rail.
If you have a fuel pressure gauge, connect it to the Schrader valve on the fuel rail. The 2010 Traverse with the 3.6L V6 engine should show 55 to 61 psi at idle. No pressure at all means the pump is not running.
Why Checking the Fuse First Saves Money
Replacing a fuel pump on a 2010 Chevy Traverse is not cheap. The part itself can cost anywhere from $150 to $400, and labor adds several hundred more. But many fuel pump "failures" turn out to be nothing more than a blown fuse or a faulty relay.
Testing the fuse and relay takes about ten minutes and costs nothing. A new fuse costs under a dollar. A new relay costs between $10 and $30. Contrast that with a $600+ fuel pump replacement, and it becomes obvious why checking fuses first is the smart move for any owner.
Additionally, the fuel pump harness connector on the Traverse is prone to corrosion and loose connections. If the fuse and relay are both good, inspect the wiring harness near the fuel pump connector. Clean it with electrical contact cleaner and ensure all pins are secure before condemning the pump itself.

Final Checklist: Fuel Pump Fuse Diagnostics for the 2010 Traverse
Here is a simple checklist you can follow when the fuel pump stops working:
1. Confirm the symptom.
Turn the key to the ON position and listen for the fuel pump hum near the rear of the vehicle.
2. Locate the underhood fuse block.
Open the hood, find the fuse box on the passenger side, and remove the cover.
3. Inspect the FSCM fuse (F34, 25A).
Pull the fuse and check for continuity with a multimeter.
4. Inspect the FUEL PUMP fuse (20A).
Pull this fuse and test it the same way.
5. Test the fuel pump relay.
Swap the relay with a known good one and see if the pump activates.
6. Check the wiring and connector.
