Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Inspect the battery for signs of damage or swelling. Replace if necessary.
3. Clean the battery terminals with a wire brush to remove corrosion.
4. Reconnect the battery terminals (positive first, then negative).

3. Starter Relay and Fuse Check

Sub-steps:
1. Locate the fuse box under the hood and find the starter relay.
2. Remove the starter relay and test for continuity with a multimeter.
3. Inspect the associated fuse and replace it if it is blown.
4. Reinstall the relay after testing or replacing.

4. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column covers to access the ignition switch.
2. Disconnect the wiring harness from the ignition switch.
3. Use a multimeter to check for continuity across the switch terminals when in the start position.
4. Replace the ignition switch if continuity is not present.

5. Starter Motor Check

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the electrical connector and battery cable from the starter.
3. Test the starter motor by applying direct power from the battery (use caution).
4. Replace the starter motor if it does not engage or spin.
