2005 Toyota Corolla Fuel Pump Fuse Location: The Complete Owner’s Guide
The bottom line: The fuel pump fuse on a 2005 Toyota Corolla is located in the engine compartment fuse box, which sits on the passenger side of the engine bay near the firewall. The specific fuse you need to check is the EFI fuse (position 13), rated at 20 amps for the 1ZZ-FE engine, or 15 amps for the 2ZZ-GE engine. Additionally, there is a second fuse labeled EFI2 (position 17) rated at 15 amps that also controls the multiport fuel injection system and can affect fuel pump operation. If both fuses are intact but the pump still isn't getting power, the problem likely lies with the fuel pump relay or a wiring issue rather than a blown fuse.
Having trouble starting your 2005 Corolla? Before you spend hundreds on a tow truck or a mechanic, checking the fuel pump fuse is one of the cheapest and easiest diagnostic steps you can do at home. A blown fuse is a common cause of a no-start condition, and replacing it costs less than a dollar. This guide walks you through exactly where to look, what to inspect, and how to confirm whether the fuse is actually your problem.
Where to Find the Fuse Box on a 2005 Toyota Corolla
Step 1: Open the Hood
The 2005 Corolla (ninth generation, model codes E120/E130) has two fuse boxes. The one you need for the fuel pump is under the hood.
- Pull the hood release lever located under the driver’s side dashboard.
- Lift the hood and secure it with the prop rod.
- Look toward the passenger side of the engine bay, near the firewall (the metal wall separating the engine from the cabin).
Step 2: Identify the Engine Compartment Fuse Box
The engine compartment fuse box is a black plastic box with a red or black cover. It sits close to the battery on the passenger side. Turn the two locking tabs and lift the cover off. On the inside of the cover, you’ll find a diagram that shows the position and function of every fuse.
Step 3: Locate Fuse Number 13 (EFI)
Once the cover is off, look for the fuse labeled EFI in position 13. Here’s what you need to know:
- For the 1ZZ-FE engine (most common): This is a 20-amp fuse.
- For the 2ZZ-GE engine (sport version): This is a 15-amp fuse.
The EFI fuse powers the multiport fuel injection system and the emission control system. It is the main fuse that supplies power to the fuel pump circuit.
Step 4: Locate Fuse Number 17 (EFI2)
Right nearby, also in the engine compartment fuse box, you’ll find fuse EFI2 in position 17. This is always a 15-amp fuse. It also feeds the multiport fuel injection system and emission control system. A blown EFI2 fuse can also stop the fuel pump from running.

| 14 | ALT-S | 5A | Charging system |
| 15 | HEAD LH LWR | 10A | Left headlight (low beam) |
| 16 | HEAD RH LWR | 10A | Right headlight (low beam) |
| 17 | EFI2 | 15A | Multiport fuel injection, emission control |
How to Check the Fuel Pump Fuse
You don’t need special tools to inspect a fuse. Here’s how:
- Turn off the engine and remove the key from the ignition. Make sure all accessories are off.
- Pull out the fuse using the fuse puller tool. Toyota conveniently places a fuse puller and spare fuses inside the engine compartment fuse box. If you can’t find the puller, a pair of needle-nose pliers works fine, just be gentle.
- Look at the metal strip inside the fuse. If the strip is intact and continuous, the fuse is good. If the strip is broken, melted, or shows a gap, the fuse is blown.
- Test for continuity if you want to be extra thorough. Use a multimeter set to the continuity or ohms setting. Place one probe on each metal blade of the fuse. A beep or a reading near zero ohms means the fuse is fine. No beep or an infinite reading means it’s blown.
- Swap with a known good fuse as another reliable test. Pull a fuse with the same amperage rating from a non-essential circuit, like the audio system (AMP, 30A) or horn (HORN, 10A), and insert it into the EFI slot. If the car starts, you’ve confirmed the original fuse was bad.
What Else Could Be the Problem?
If both the EFI and EFI2 fuses are intact, the fuel pump relay could be at fault.
The Fuel Pump Relay
On the 2005 Corolla, the fuel pump relay is located in the same engine compartment fuse box, right next to the EFI fuse. It’s a small, square, black component. When you turn the key to the ON position, the relay clicks and sends power to the fuel pump for about two seconds to prime the system.
- How to test the relay: Turn the key to the ON position (don’t crank the engine) and listen for a faint click from the fuse box. If you don’t hear a click, the relay may be stuck or failed.
- A quick trick: Give the relay a gentle tap with the handle of a screwdriver. Sometimes a stuck relay will free up and start working again. This is a temporary fix, so if it works, plan on replacing the relay soon.
- Swap test: Like the fuse, you can swap the fuel pump relay with an identical relay from another circuit, if one is available. Check the owner’s manual or the fuse box diagram to see if another relay has the same part number.
Other Supporting Fuses
Some guides also recommend checking a few other fuses in the engine compartment that relate to the fuel injection and engine control systems. These include small 7.5-amp and 10-amp fuses that feed the engine control module and other sensors. While less likely to cause a complete no-start, a blown fuse here can still disrupt fuel delivery.
Why the Fuse Box Cover Diagram Matters
Always check the diagram on the inside of the fuse box cover before pulling any fuse. Toyota updates the design slightly from year to year and even between trim levels. The diagram printed on the cover is specific to your car and shows the exact amperage for each fuse. Using a fuse with the wrong amperage rating, especially a higher one, can damage the wiring or start a fire. Never replace a 15-amp fuse with a 20-amp fuse just because it fits.
What to Do If the Fuse Keeps Blowing
If you replace the EFI fuse and it blows again right away, you have a short circuit somewhere in the fuel injection or fuel pump wiring. Do not keep replacing the fuse and hoping for the best. A short circuit can cause more damage and, in the worst case, a fire. Here are a few things to check:
- Inspect the fuel pump wiring harness under the rear seat, where the fuel pump access panel is located. Look for chafed, pinched, or melted wires.
- Check the fuel pump itself. A failing fuel pump can draw too much current and blow the fuse. You can test the pump’s resistance with a multimeter, but this requires some electrical know-how.
- Take it to a qualified mechanic. If you’re not comfortable with electrical diagnostics, a professional can trace the short circuit safely and find the root cause.
Using the Spare Fuses
Toyota includes spare fuses in the engine compartment fuse box, typically in positions 4, 5, and 6, labeled SPARE with ratings of 30A, 15A, and 10A. If you need a 15-amp fuse for the EFI2 position, you can use the spare 15A. If your car has the 1ZZ-FE engine and you need a 20A for the EFI position, check if there’s a spare 20A; some model years may not include one. In that case, you’ll need to purchase a new fuse from an auto parts store. A pack of assorted fuses costs a few dollars and is a smart thing to keep in your glove box.
A Word on the Interior Fuse Box
Some older guides mention that the fuel pump fuse is located in the interior fuse box under the dashboard. For the 2005 Corolla, this is not the case. The fuel pump-related fuses (EFI and EFI2) are in the engine compartment fuse box. The interior fuse box, located below the driver’s side of the instrument panel, handles accessories like the cigarette lighter, power windows, turn signals, and the audio system. The only fuel-related items there are fuses that support the engine control system, such as the AM2 fuse in position 22 (15A) which helps the starting and fuel injection system, and the STOP fuse in position 23 (15A) which also ties into the fuel injection system. These are worth a quick check if the engine cranks but won’t start and the EFI fuses look good.
Summary Checklist
If your 2005 Corolla won’t start and you suspect the fuel pump, follow this simple checklist:
- Open the hood and locate the engine compartment fuse box on the passenger side.
- Remove the cover and check the diagram on the inside.
- Pull fuse 13 (EFI) — 20A for 1ZZ-FE, 15A for 2ZZ-GE.
- Pull fuse 17 (EFI2) — 15A.
- Inspect the metal strip for a break or melting.
- Test with a multimeter or swap with a good fuse.
- If fuses are fine, check the fuel pump relay next to the EFI fuse. Tap it gently to see if it’s stuck.
- Check the AM2 and STOP fuses in the interior panel under the dash if the engine still won’t start.
- If the fuse blows again immediately, there’s a short circuit. Stop and get professional help.
