Solution

1. Preparation

Tools Required: Multimeter, socket set, battery load tester, fuse puller
Disconnect the negative battery terminal to avoid electrical shorts.
Allow the vehicle to cool down if it was running prior to inspection.

2. Battery Inspection and Replacement

Sub-steps:
1. Reconnect the battery terminals after ensuring no corrosion is present.
2. If the battery voltage is low, connect a battery charger and charge it fully.
3. If the battery fails the load test, remove it using a socket set, and replace it with a new, compatible battery (Group Size 51R or as specified).
4. Reconnect the battery terminals securely.

3. Fuse Check and Replacement

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
2. Use the fuse puller to remove and inspect fuses related to the ignition and starter circuits.
3. Replace any blown fuses with the correct amperage rating as indicated on the fuse box cover.

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, typically found near the transmission.
2. Inspect the electrical connections to the starter for tightness and corrosion.
3. If necessary, remove the starter motor using a socket set.
4. Test the starter motor by connecting it directly to a battery to confirm it spins.
5. Replace the starter if it does not function properly.

5. Ignition Switch Testing

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Use a multimeter to test for continuity across the ignition switch terminals when the key is turned to the "Start" position.
3. If there is no continuity, replace the ignition switch.
