Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Ensure the vehicle is in a safe, well-ventilated area and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery.
Sub-step 2: Clean the battery terminals with a wire brush to remove corrosion.
Sub-step 3: Reconnect the terminals securely and ensure they are tight.

3. Fuel System Check

Sub-step 1: Locate the fuel pump fuse in the fuse box and inspect it; replace if blown.
Sub-step 2: If the fuse is intact, access the fuel pump relay and test it with a multimeter to ensure it is functioning correctly.
Sub-step 3: If the relay is faulty, replace it with a new one.

4. Ignition System Inspection

Sub-step 1: Inspect the ignition switch by removing the steering column cover to access it.
Sub-step 2: Test the ignition switch with a multimeter to check for continuity when turned to the START position.
Sub-step 3: If defective, replace the ignition switch.

5. Starter Motor Check

Sub-step 1: Locate the starter motor under the vehicle, typically near the transmission.
Sub-step 2: Check the wiring and connections to the starter motor for any damage or corrosion.
Sub-step 3: Use a multimeter to test for voltage at the starter terminal when the ignition is turned to START; if no voltage is present, further investigate the circuit.
