Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Wrench set
- Screwdriver set
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals and cable ends using a wire brush.
3. Reconnect the battery terminals securely.

3. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box and identify the starter relay.
2. Swap the starter relay with a similar relay to test functionality.
3. Inspect and replace any blown fuses related to the starting system.

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (usually mounted on the transmission).
2. Disconnect the electrical connector from the starter.
3. Check for corrosion or damage at the terminals.
4. Use a multimeter to test for voltage at the starter terminal when attempting to crank.
5. If no voltage is present, further inspect wiring leading to the starter.

5. Starter Replacement (if necessary)

Sub-steps:
1. Remove the bolts securing the starter to the engine.
2. Carefully remove the starter from the mounting location.
3. Install the new starter motor and secure with bolts (torque to manufacturer specifications).
4. Reconnect the electrical connector and battery terminals (positive first, then negative).
