Solution

1. Preparation

Gather necessary tools: multimeter, jumper cables, socket set, and safety gloves.
Ensure the vehicle is in a safe area and on level ground.
Disconnect the battery negative terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Clean the battery terminals using a wire brush to remove corrosion.
Sub-step 2: Tighten the battery terminal connections securely.
Sub-step 3: If the battery is weak (below 12.4 volts), recharge it using a battery charger or replace it if necessary.

3. Starter Relay Check

Sub-step 1: Locate the starter relay in the fuse box.
Sub-step 2: Remove the starter relay and inspect for signs of damage.
Sub-step 3: Replace the relay with a new one or swap with a similar relay to test functionality.

4. Starter Motor Inspection

Sub-step 1: Locate the starter motor, usually mounted on the transmission bell housing.
Sub-step 2: Check wiring connections to the starter motor for looseness or damage.
Sub-step 3: If necessary, remove the starter motor using a socket set, and bench test it to confirm it functions correctly.

5. Reassembly and Final Steps

Sub-step 1: Reconnect the battery negative terminal.
Sub-step 2: Start the vehicle to confirm that the issue is resolved.
