The starter relay in a 2013 Honda Accord is in the engine‑bay fuse/relay box, labeled STARTER on the cover diagram, and it sits on the driver’s side near the strut tower by the battery.
Below is a practical guide to locating the relay, understanding its role, and what to do if you’re troubleshooting a starting issue.
Location and what to look for
On most 2013 Accord models, the starter relay is part of the under‑hood fuse/relay box. This box is usually mounted in the engine bay on the driver’s side. The cover of the box has a diagram showing the relay layout, including a relay labeled STARTER or ST. If you’re unsure, check the diagram on the underside of the lid or consult the owner’s manual for the exact map for your engine option (2.4L I4 or 3.5L V6).
To confirm the location, follow these steps:
- Open the hood and locate the under‑hood fuse/relay box on the driver’s side of the engine bay near the strut tower and battery.
- Remove the lid and read the diagram to identify the STARTER (or ST) relay.
- Carefully pull the STARTER relay straight out to inspect or replace it, noting its exact position for reinstallation.
- If the diagram doesn’t clearly label STARTER, reference the owner’s manual’s fuse/relay map for your trim and engine.
If your Accord uses a different fuse box arrangement or you’re working on a specific variant, you may also find a small relay cluster in a secondary power distribution box located closer to the firewall. In most cases, though, the starter relay is in the engine bay’s main under‑hood box.
How to troubleshoot or replace
Diagnosing a starter relay issue typically starts with confirming power to the relay and its control signal. Look for symptoms such as a no‑crank condition, a single click when turning the key, or intermittent starting problems. Replacing the relay is a straightforward job that involves removing the old relay and seating a new one in the same socket, making sure it fits snugly.
Before you begin any electrical work, ensure safety by turning off the ignition and, if you’re comfortable, disconnecting the negative battery terminal to prevent sparks or shorts. If you’re unsure about the process, consult a professional technician or refer to the service manual for your exact engine configuration.
Common signs of a failing starter relay
If the starter relay is failing, you might notice one or more of the following:
- No engine crank when turning the key or pressing Start
- Rapid, repeated clicking from the engine bay when attempting to start
- Intermittent starting behavior that seems to come and go
- Starter motor runs (or engages) but the engine does not crank, suggesting a power/ground issue in the circuit
If you experience these symptoms, inspect the STARTER relay first, along with associated wiring and connections. Cleaning corroded terminals, ensuring tight connections, or replacing a faulty relay can often resolve the issue without more invasive work.
Maintenance and tips
Regularly inspect the under‑hood fuse/relay box for signs of corrosion, loose connectors, or damaged wires. Keep the cover clean and dry, and replace any damaged relays with the correct part number for your engine. If you replace the relay and starting problems persist, there may be a related issue in the starting circuit, such as a faulty ignition switch, bad wiring, or a tired battery.
Summary
For a 2013 Honda Accord, the starter relay is located in the engine‑bay under‑hood fuse/relay box on the driver’s side near the strut tower, clearly labeled STARTER on the lid’s diagram. Use the diagram to identify the exact relay location, and replace it if you experience starting problems or a no‑crank condition. If in doubt, consult the owner’s manual or a qualified technician for guidance.
