Solution

1. Preparation

Gather tools: multimeter, jumper cables, socket set, and screwdriver.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Check Battery Condition

Use a multimeter to measure the battery voltage. A healthy battery should read approximately 12.6 volts or higher.
If the voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.

3. Clean and Secure Battery Connections

Disconnect the negative battery terminal first, followed by the positive terminal.
Clean the terminals and cable connectors using a wire brush.
Reconnect the positive terminal first, then the negative terminal, ensuring they are tight.

4. Jump-Start the Vehicle

Connect jumper cables to a known good battery following the proper sequence (positive to positive, negative to negative).
Start the donor vehicle, then attempt to start the Honda Accord.

5. Inspect and Replace the Starter Motor

If the vehicle still does not start, remove the starter motor:
- Disconnect the battery.
- Remove any components obstructing the starter (such as heat shields).
- Unbolt the starter motor from the engine block.
- Disconnect the electrical connections from the starter.
Install the new starter motor in reverse order, ensuring all bolts are torqued to manufacturer specifications.
