Solution

1. Preparation

Gather tools such as a socket set, multimeter, and OBD-II scanner.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery cable to prevent any electrical short.

2. Check Battery Connections

Inspect the battery terminals for corrosion. Clean any corrosion using a wire brush.
Tighten any loose connections to ensure a solid electrical connection.

3. Test the Starter Motor

Locate the starter motor under the vehicle (usually near the transmission).
Use jumper cables to connect the positive terminal of the battery to the starter motor's positive terminal and the negative cable to a good ground.
If the starter motor engages and the engine cranks, the starter is functional; otherwise, it may need replacement.

4. Inspect Fuses

Locate the fuse box and check the starter and ignition system fuses.
Replace any blown fuses with the same amperage rating.

5. Check Ignition Switch

Use a multimeter to test the ignition switch by checking for continuity between terminals when the key is turned to the "start" position.
If the ignition switch is faulty, replace it.

6. Inspect Neutral Safety Switch

If applicable, check the neutral safety switch for proper operation by ensuring it allows current flow when the vehicle is in park or neutral.
Adjust or replace the switch if necessary.
