2009 Toyota Camry Fuel Pump Fuse Location: The Complete Owner's Guide

The fuel pump fuse on a 2009 Toyota Camry is located in the engine compartment fuse box, which sits near the battery on the driver's side of the engine bay. This is the first place you should check when your Camry cranks but refuses to start, because a blown fuse is one of the most common and cheapest reasons for a no-start condition. The engine compartment fuse box is a black rectangular unit with a removable lid, and the diagram printed on the underside of the lid will help you identify the correct fuse. Before you spend any money on parts or call a tow truck, take five minutes to inspect this fuse, because it could save you a lot of time and frustration.

The 2009 Toyota Camry actually has two fuse boxes, and understanding which one does what is critical. The first fuse box is located under the dashboard on the driver's side, and it handles interior functions like the radio, lights, doors, power windows, and seat heaters. The second fuse box is in the engine compartment, and this one manages high-current systems like the starter motor, alternator, fuel injectors, and cooling fans. The fuel pump fuse lives in the engine compartment box, not the interior one, so that is where you need to look first.

Where Exactly Is the Engine Compartment Fuse Box?

Open the hood of your 2009 Camry and look toward the driver's side, near the battery. You will see a black rectangular fuse box with a removable lid. It may be labeled "Main Fuse Box" or "Engine Room Fuse Block." Remove the lid by pressing the release tabs on the sides, and set it aside. On the underside of that lid, you will find a printed diagram that maps out every fuse and relay in the box. This diagram is your best friend, because it tells you exactly which slot is the fuel pump fuse and what amperage rating it should have.

If the diagram on the lid has faded or become hard to read, which happens on many older vehicles, you can also check the owner's manual for the same information. The fuse you are looking for is typically rated at 20 to 30 amps, and it is usually grouped with other powertrain-related components like the EFI (Electronic Fuel Injection) fuses and the fuel pump relay.

Fuse Box Diagram: What Does the Fuel Pump Fuse Look Like?

The engine compartment fuse box on the 2009 Toyota Camry contains a series of numbered fuses. Based on the fuse box diagrams for this vehicle, here is the layout you should expect to see when you open the cover:

1. Fuse #19 – EFI MAIN (30A): This is the main electronic fuel injection fuse, which powers the EFI system and is directly related to fuel delivery.
2. Fuse #20 – EFI NO.3 (10A): Supports the multiport fuel injection system.
3. Fuse #21 – EFI NO.2 (15A): Also supports the multiport fuel injection system.
4. Fuse #23 – A/F (20A): This fuse handles the air-fuel ratio sensor, which is part of the fuel injection system.
5. Fuse #25 – EFI NO.1 (10A): Powers the theft deterrent system, smart key system, and the multiport fuel injection system.

The fuel pump relay is known as the "C/OPN" (Circuit Opening) relay, and it works in tandem with the EFI relay to control power to the fuel pump. If either the fuse or the relay fails, the fuel pump will not receive power, and your engine will not start.

How to Check If the Fuel Pump Fuse Is Blown

Checking the fuel pump fuse is a straightforward process that requires no special skills, but you do need a basic understanding of what a good fuse looks like versus a blown one. Here is how to do it:

1. Turn off the vehicle and remove the keys from the ignition. Safety first, and you need the ignition completely off before you touch anything electrical.
2. Locate the fuse box in the engine compartment and remove the lid, as described above.
3. Find the fuse slot that corresponds to the fuel pump circuit. Look for a fuse that may be labeled "EFI" or "A/F" as described earlier, and check the diagram on the fuse box lid.
4. Pull the fuse out using a fuse puller or a pair of needle-nose pliers. The fuse box usually includes a small fuse puller tool that clips onto the fuse.
5. Inspect the fuse carefully. Look at the metal wire inside the fuse. If the wire is intact and you can see it clearly connecting both sides, the fuse is good. If the wire is broken, melted, or charred, the fuse is blown and needs to be replaced.

If the fuse appears intact, you can confirm it with a multimeter. Set the multimeter to test continuity, touch the probes to both metal terminals of the fuse, and listen for a beep. A reading of zero means the fuse is good. Any other reading, or no beep at all, means the fuse is blown.

2009 Toyota Camry Fuel Pump Fuse Location: Step-by-Step Walkthrough

Let me walk you through the entire process from start to finish so you can do this with confidence in your driveway or garage.

Step 1: Park the car on a flat surface and turn off the engine. Put the parking brake on and remove the keys from the ignition. Make sure the car is completely off before you open the hood.

Step 2: Open the hood and locate the fuse box. The fuse box is on the driver's side, near the battery. It's a black plastic box with a lid that says "Fuse Box" or "Engine Room Fuse Block." If you cannot find it, check the owner's manual.

Step 3: Remove the fuse box lid. Press the release tabs on the sides of the lid and lift it off. Turn it over and look at the diagram printed on the underside. This diagram shows the location and amperage of every fuse in the box.

Step 4: Identify the fuel pump fuse. Look for fuses labeled "EFI MAIN," "EFI NO.2," "EFI NO.3," or "A/F" on the diagram. The EFI MAIN fuse is typically a 30-amp fuse, and it is the main power source for the fuel injection system.

Step 5: Check the fuse. Use the fuse puller tool that came with the vehicle or a pair of needle-nose pliers to pull the fuse out of its slot. Inspect the metal strip inside the fuse. If the strip is broken, the fuse is blown and needs to be replaced.

Step 6: Replace the fuse if necessary. If the fuse is blown, replace it with a new fuse of the exact same amperage rating. Never use a higher-rated fuse, because this can damage the wiring and create a fire hazard.

Step 7: Test the system. After replacing the fuse, turn the ignition to the "ON" position (without starting the engine). Listen near the rear of the vehicle, by the fuel tank, for the fuel pump prime. You should hear a distinct humming or whirring sound for 2-3 seconds. If you hear it, the fuel pump is receiving power and working. If you do not hear it, the problem may be elsewhere.

What Else Could Be Wrong If the Fuse Is Good?

If you have checked the fuel pump fuse and it is fine, or you replaced a blown fuse but the problem persists, there are several other components you should investigate.

1. The Fuel Pump Relay. As mentioned earlier, the fuel pump relay on a 2007-2011 Toyota Camry is integrated into the engine bay fuse box and known as the "C/OPN" (Circuit Opening) relay. This relay works with the EFI relay to control power to the fuel pump. If this relay fails, the fuel pump will not activate. You can test it by swapping it with a similar relay from the fuse box, such as the A/C compressor relay. If the problem moves with the relay, you have found the faulty part.

2. The Fuel Pump Itself. If the fuse and relay are both good, the fuel pump may be failing. Symptoms of a bad fuel pump include cranking but no start, random stalling while driving, lack of power during acceleration, and a loud, high-pitched whining noise coming from the rear seat area.

3. The Fuel Filter. A clogged fuel filter can restrict fuel flow to the engine, causing performance problems even if the pump is working. This is less likely to cause a complete no-start, but it can cause poor acceleration and surging.

4. The Wiring. The wiring harness between the fuse box and the fuel pump can become corroded or damaged, preventing power from reaching the pump. Inspect the wiring for signs of damage, especially in areas where it rubs against metal edges.

Common Signs of a Blown Fuel Pump Fuse

So, how do you know if the fuel pump fuse is the culprit in the first place? Here are the most common symptoms:

1. Engine cranks but will not start. This is the most common symptom. The starter motor works fine, the engine turns over, but there is no fuel reaching the injectors.
2. No fuel pump prime noise. When you turn the ignition to "ON," you should hear the fuel pump hum for a few seconds. If you hear nothing, the pump is not receiving power.
3. Sudden loss of power while driving. If the fuse blows while you are driving, the engine may stall suddenly and refuse to restart.
4. Intermittent starting issues. If the fuse is loose or making poor contact, you may experience intermittent starting problems that come and go.

2009 Toyota Camry Fuel Pump Fuse Location: The Bottom Line

The fuel pump fuse on a 2009 Toyota Camry is located in the engine compartment fuse box, on the driver's side near the battery. It is typically one of the EFI-related fuses, such as the EFI MAIN (30A) fuse. Checking this fuse is the logically the first step when your Camry has a no-start condition, because it is fast, free, and does not require any special tools. By following the steps outlined in this guide, you can quickly determine whether the fuse is the problem or whether you need to look deeper into the fuel system.

If you have confirmed that the fuse is not the issue and the relay is also working, the problem may be the fuel pump itself. A failing fuel pump shows symptoms similar to a blown fuse, and catching it early can prevent you from being stranded on the side of the road.
