Where is the starter relay located on a 2013 Honda Accord?

On a 2013 Honda Accord, the starter relay is located in the engine compartment fuse/relay box on the driver’s side near the battery. It’s typically labeled ST or START on the lid’s diagram.

This guide explains the standard location, how to identify the correct relay, and what to check if the engine won’t turn over. While this is the most common setup for 2013 Accords, there can be variation by trim or regional spec, so always reference the fuse box diagram for your VIN.

Where to look in the engine compartment

The starter relay is most often found in the engine compartment fuse/relay box (the large black box with a removable cover) on the driver’s side of the engine bay, near the battery. The box cover features a schematic that labels each relay, including the starter circuit.

To prepare for identification, locate the relay box and remove the lid carefully to read the diagram. The starter relay may be labeled as ST, START, or with a symbol indicating the starter circuit.

• Open the engine compartment fuse/relay box and identify the relay labeled ST/START according to the diagram on the cover.


• Confirm the relay’s position by matching the position in the diagram to the physical relays inside the box.


• Inspect the relay and its connections for signs of wear or burning, and test the relay if you have the proper tools.

Concluding the inspection, ensure the battery connections and grounding are solid, as a weak supply can mimic a faulty starter relay.

Alternative locations and notes

In some Honda Accord configurations or markets, the starter relay is integrated into the IPDM-E (intelligent power distribution module) assembly, located near the firewall or behind the right-side front wheel well. If you cannot find a standalone starter relay in the engine fuse box, check the IPDM-E or refer to the official manual for your exact VIN.

For most owners, the engine compartment fuse/relay box remains the primary location. If you’re unsure or uncomfortable with inspection, consult a professional mechanic.

What to do if the starter won’t engage

Begin with the basics: verify the battery is charged, the battery terminals are clean and tight, and the ignition circuit is sending power. If the battery is healthy, test or swap the starter relay using a known-good unit, following safe electrical procedures.

• Locate the starter relay in the engine compartment fuse box (as described above).


• Remove and test the relay with a multimeter or swap with a similar relay to see if the issue resolves.


• If swapping the relay doesn’t fix the problem, rule out the starter motor, ignition switch, and related wiring.

These steps help determine whether the issue is a faulty relay, a weak battery, or a more complex electrical fault.

Summary

The starter relay on a 2013 Honda Accord is typically in the engine compartment fuse/relay box on the driver’s side near the battery, labeled ST or START. Some models may house the relay in the IPDM-E module. Always consult the lid diagram or the owner’s manual for your exact VIN and trim, and consider professional help for electrical diagnostics.
