Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals using a wire brush.
3. Test the battery with a multimeter; if below 12.4 volts, replace the battery.
4. Install the new battery, connecting positive first, then negative.

3. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box under the hood.
2. Remove the starter relay and inspect it for damage. Replace if faulty.
3. Check the starter fuse; remove it and inspect visually. Replace if blown.

4. Starter Inspection and Replacement

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Disconnect the wiring harness from the starter.
3. Remove the mounting bolts using a socket set and carefully extract the starter.
4. Install the new starter by reversing the removal steps, ensuring all connections are secure.

5. Ignition Switch Check

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Inspect the ignition switch for wear or damage.
3. Replace the ignition switch if faulty by disconnecting the wiring harness and unscrewing it from the column.
