2005 Toyota Camry Fuel Pump Location: Complete Guide to Finding and Replacing It

The bottom line: The fuel pump on a 2005 Toyota Camry is located inside the fuel tank, mounted to the top of the fuel pump module assembly, and you can access it through a service cover underneath the rear seat cushion — you do not need to drop the fuel tank to get to it. This design makes the pump surprisingly accessible for a DIY repair, and most owners with basic hand tools can complete the job in about 1.5 to 3 hours.

If your Camry is cranking but not starting, stalling at operating temperature, or making a whining noise from the back seat area, the fuel pump is a prime suspect. Before you tear anything apart, it helps to know exactly where the pump lives and how to get to it safely. This guide walks you through the location, the symptoms of a failing pump, the step-by-step replacement process, and how to choose the right replacement part for your 2005 Camry.

Where Exactly Is the Fuel Pump on a 2005 Toyota Camry?

The electric fuel pump sits inside the fuel tank, but unlike many older vehicles where you have to drop the tank from underneath, Toyota placed a metal access panel right in the floorpan under the rear seat. This service cover is circular or oval in shape and is held in place by a few screws or bolts.

Here is the exact path from inside the cabin to the pump:

  1. Remove the rear seat cushion. The bottom cushion pops out by lifting the front edge firmly. Some trims use a 12mm bolt at the front edge that you remove first.
  2. Locate the metal access cover. Once the seat is out, you will see a metal panel on the floor, directly above the fuel tank.
  3. Unscrew the cover. Use a Phillips screwdriver or a 10mm socket depending on what holds the panel in place.
  4. Inside, you will see the top of the fuel pump module. The electrical harness and fuel line are connected right there, meaning the pump itself is just below that opening, submerged in fuel.

This layout covers the 2002 through 2006 model years, including the 2005 Camry. The 2007 model also uses a similar under-seat access design.

How to Diagnose a Failing Fuel Pump Before You Replace It

Not every no-start or stalling issue is caused by the fuel pump itself. Before you invest in a new pump, run through these simple checks to avoid wasting time and money.

1. Listen for the Prime Buzz

Turn the ignition key to the ON position but do not crank the engine. You should hear a quiet hum from the rear seat area for about two seconds. That is the pump pressurizing the fuel system. If you hear nothing, the pump may not be receiving power or the motor itself may be dead.

2. Check the Fuel Pump Relay and Fuse

On the 2005 Camry, the fuel pump relay, labeled C/OPN, lives in the engine bay fuse and relay box. Open the fuse box lid and look at the diagram printed on the underside to confirm the exact location. Pull the relay and test it for clicking when power is applied, or swap in a known-good relay to see if the pump primes. Also check the EFI fuse in both the engine bay and the cabin fuse panel.

3. Verify Fuel Pressure with a Gauge

Connect a fuel pressure gauge to the Schrader valve on the fuel rail. With the key on, the pressure should climb to the manufacturer's specification. A reading that stays at zero or drops quickly after the key is off points to a bad pump or a clogged filter.

4. Watch for These Common Symptoms

  • Crank but no start: The engine turns over but never fires because fuel is not reaching the injectors.
  • Long crank before start: It takes several seconds of cranking before the engine catches.
  • Stalling at temperature: The car dies when the engine gets hot, then restarts after cooling down.
  • Whining noise from the tank area: A high-pitched hum from the rear seat suggests worn pump bearings or a clogged strainer.
  • Loss of power under load: The engine struggles during acceleration or on hills because fuel pressure drops.

How to Replace the Fuel Pump on a 2005 Toyota Camry

Once you have confirmed the pump is the problem, you can proceed with the replacement. The job is rated as intermediate difficulty, and most DIYers finish it in about 1.5 to 3 hours.

Tools You Will Need

Here is the list of tools to gather before you start:

  1. Safety glasses and nitrile gloves
  2. 10mm, 12mm, and 14mm sockets with ratchets
  3. Flat-blade screwdriver (small) and Phillips screwdriver
  4. Trim clip removal tool
  5. Needle-nose pliers
  6. A non-sparking brass punch and a small hammer (for the lock ring)
  7. A catch pan and shop towels
  8. A torque wrench (5 to 60 Nm range)

Step 1: Relieve Fuel System Pressure

Working with a pressurized fuel system is dangerous, so do not skip this step.

  1. Open the hood and remove the negative battery cable with a 10mm socket.
  2. Locate the fuel pump relay or fuse in the engine bay fuse box and pull it out.
  3. Reconnect the negative battery cable temporarily.
  4. Start the engine and let it run until it stalls from fuel starvation. Then crank for an additional 2 to 3 seconds to bleed remaining pressure.
  5. Turn the key off and disconnect the negative battery cable again.

Tip: Open the gas cap to release any built-up tank pressure before you begin working.

Step 2: Remove the Rear Seat Cushion

From the back seat footwell area, look for the seat cushion retainers. If there are bolts, remove them with a 12mm socket (torque to 37 Nm on reassembly). If your cushion uses clips, use a trim tool to pop the front edge up, then lift the cushion and set it aside.

Step 3: Open the Fuel Pump Service Cover

With the seat out, you will see the metal service panel on the floor. Remove the screws or bolts holding it down, lift the cover, and wipe away any dust or debris so nothing falls into the tank when you open it.

Step 4: Disconnect the Electrical Connector and Fuel Line

Unplug the pump module electrical connector by releasing the lock tab with a small flat-blade screwdriver. Place a catch pan and shop towels under the fuel line connection. Carefully release the quick-connect fuel line by lifting the connector lock and squeezing the tabs by hand, then pulling the line straight off. Avoid using pliers unless absolutely necessary because the plastic connector is easy to crush.

Step 5: Remove the Pump Module Lock Ring

Mark the module and tank alignment with a marker so you reinstall the pump in the same orientation. Use a non-sparking brass punch and a small hammer to tap the lock ring counterclockwise until it releases. Remove the lock ring and set it aside.

Step 6: Pull the Old Assembly Out

Carefully lift the entire fuel pump module straight up and out of the tank. Be gentle with the float arm on the fuel level sensor, as it bends easily and will cause the fuel gauge to read incorrectly. The assembly will be wet with fuel, so hold it over the catch pan while you work.

Step 7: Install the New Fuel Pump Assembly

If you purchased a complete fuel pump module assembly, you do not need to disassemble anything — this is the direct swap approach. Slide the new assembly into the tank in the correct orientation, ensuring the float arm is free. Replace the lock ring and tap it clockwise to secure. Torque the retaining bolts to specs if your assembly uses bolts (the 2002-2006 Camry uses 8mm bolts).

Step 8: Reconnect Everything and Test

Reconnect the electrical harness and fuel line. Reinstall the service cover and the rear seat cushion. Reconnect the negative battery cable, then cycle the ignition to the ON position for two seconds, off for ten, and repeat 5 to 10 times to prime the system. Then start the engine and check for leaks around the fuel line connection.

Fuel Pump vs. Fuel Pump Module: Which Should You Buy?

The most common mistake owners make when ordering a replacement is buying only the electric pump motor when the entire assembly is what they actually need. While the bare motor is cheaper, it adds complexity — you have to disassemble the module, transfer the old sender and housing, and risk damaging old components that may be near the end of their life.

For a reliable long-term repair, order the complete fuel pump module assembly, which includes the pump motor, the fuel strainer (sock), the fuel level sender, and the housing. This is a direct swap that takes less time and gives you peace of mind knowing every component inside the tank is fresh.

The OEM part number for the fuel pump on a 2005 Camry is 23220-28070 or 23220-28360, depending on your exact engine configuration. Verify the number against your VIN before ordering.
