Solution

1. Preparation

Gather all necessary tools and replacement parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Use a wire brush to clean any corrosion from the battery terminals.
Reconnect the terminals securely and check for tightness.
If the battery is weak, replace it with a new one of the same specifications (typically a Group 24F for Honda Accord).

3. Starter Relay Testing

Locate the starter relay in the fuse box (refer to the owner's manual for the exact location).
Remove the relay and test it with a multimeter for continuity.
If faulty, replace it with a new relay.

4. Starter Motor Examination

Remove the starter motor by disconnecting the electrical connections and unbolting it from the engine.
Inspect the starter for worn brushes or damage.
If faulty, replace it with a new starter motor and ensure proper alignment during installation.

5. Reassemble and Final Checks

Reconnect the negative battery terminal.
Tighten all connections and ensure there are no exposed wires.
Start the vehicle to verify proper function.
