The starter relay is typically located in the engine compartment’s under-hood fuse/relay box on the driver’s side, near the battery, and is labeled ST or STA on the box diagram.
In more detail, the starter relay acts as the switch that energizes the starter solenoid when you turn the key. For most 2000 Civics, you’ll find this relay in the under-hood fuse/relay box; if it isn’t there, check the interior fuse box behind the glove box or consult the owner’s manual for the exact diagram for your trim.
Location in the engine bay
The under-hood fuse/relay box is usually mounted on the driver’s side of the engine bay, near the battery and close to the left fender. The lid carries a diagram that marks each relay, including the starter one.
Identifying the starter relay
On the diagram, look for a relay labeled ST, STA, START, or Starter. The exact designation can vary by model year and market, but it will be one of the relays in that box.
Note: Some Civics may not have a separate starter relay in the engine bay box; the ignition switch wiring could energize the starter solenoid directly or through a different configuration. If you cannot locate a dedicated starter relay in the engine bay, consult the service manual for your VIN and trim to confirm the correct layout.
Use these steps to locate the starter relay in the under-hood fuse box.
- Open the hood and locate the under-hood fuse/relay box on the driver’s side of the engine bay, near the battery.
- Remove the lid and inspect the diagram inside or on the lid to identify the relay designated for the starter (ST/STA/START).
- Confirm the correct relay by tracing the wiring: a control signal from the ignition switch goes to the relay, and the relay energizes the heavy feed to the starter solenoid.
- If you can’t find a starter relay in the engine bay box, check the interior fuse box behind the glove box or consult the owner's manual/service manual for your specific trim.
These steps should help you locate and identify the starter relay for your 2000 Honda Civic in most configurations.
Summary
For a 2000 Honda Civic, the starter relay is usually in the engine compartment’s under-hood fuse/relay box on the driver’s side near the battery, labeled ST or STA on the lid diagram. If it isn’t there, check the interior fuse box behind the glove box or refer to the manual for your model’s exact layout. Verifying the relay, its signal wiring from the ignition switch, and the power feed to the starter are key checks when diagnosing starting issues.
