Solution

1. Preparation

Gather tools: Multimeter, OBD-II scanner, socket set, torque wrench, and safety gloves.
Ensure the vehicle is in a safe location with the parking brake engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery to prevent electrical shorts.
Sub-step 2: Clean the battery terminals with a wire brush and reconnect them securely.
Sub-step 3: If the battery is below 12.4 volts, jump-start or replace the battery as necessary.

3. Ignition Switch Testing

Sub-step 1: Locate the ignition switch beneath the steering column.
Sub-step 2: Disconnect the wiring harness from the ignition switch.
Sub-step 3: Use a multimeter to check for continuity in the switch when turned to the 'start' position. Replace if defective.

4. Starter Motor Check

Sub-step 1: Locate the starter motor under the vehicle.
Sub-step 2: Disconnect the power supply from the starter motor.
Sub-step 3: Perform a bench test on the starter motor using a direct battery connection to ensure it engages properly. Replace if faulty.

5. Fuel System Inspection

Sub-step 1: Locate the fuel pump relay in the fuse box.
Sub-step 2: Remove the relay and test it for continuity with a multimeter. Replace if defective.
Sub-step 3: Inspect the fuel pump fuse for continuity and replace if necessary.
