Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver set, and safety gloves.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-step 1: Clean battery terminals with a wire brush to remove corrosion.
Sub-step 2: Tighten the battery terminal connections securely.
Sub-step 3: If the battery voltage is low, jump-start the vehicle or replace the battery if necessary.

3. Starter Motor Inspection

Sub-step 1: Locate the starter motor (typically near the engine block).
Sub-step 2: Disconnect the wiring harness from the starter motor.
Sub-step 3: Remove the starter motor bolts using a socket set and remove the starter from the vehicle.
Sub-step 4: Bench test the starter motor by connecting it directly to a charged battery to ensure it engages.

4. Ignition Switch Testing and Replacement

Sub-step 1: Remove the steering column cover by unscrewing the retaining screws.
Sub-step 2: Locate the ignition switch and disconnect the wiring harness.
Sub-step 3: Test the ignition switch using a multimeter for proper continuity when turned.
Sub-step 4: If faulty, replace the ignition switch with a new one and reassemble.

5. Reassembly and Final Checks

Sub-step 1: Reinstall the starter motor and ensure all bolts are torqued to manufacturer specifications.
Sub-step 2: Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
Sub-step 3: Recheck all connections and covers to ensure everything is secured.
