Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Check and Replacement

Sub-step 1: Clean the battery terminals using a wire brush to remove any corrosion.
Sub-step 2: If the battery voltage is below 12.4V, charge the battery using a battery charger.
Sub-step 3: If the battery is old (typically over 3-5 years), consider replacing it with a new one.

3. Starter Inspection

Sub-step 1: Remove the starter motor from the engine by unbolting it (usually 2-3 bolts). Use a socket set for this task.
Sub-step 2: Test the starter motor by connecting it directly to a fully charged battery. If it does not engage, the starter is faulty and should be replaced.
Sub-step 3: If the starter motor works, inspect the wiring leading to the starter for damage or disconnection.

4. Ignition Switch and Fuses

Sub-step 1: If the starter is functioning, check the ignition switch functionality by testing continuity with a multimeter when the key is turned.
Sub-step 2: Inspect all relevant fuses (starter and ignition) and replace any that are blown.
