Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, multimeter, socket set, safety gloves, and safety glasses.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery and Connections

Inspect Battery: Clean the battery terminals using a wire brush. If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery.
Secure Connections: Tighten any loose connections at the battery and ensure there are no signs of corrosion.

3. Ignition and Starter System

Check Ignition Switch: If no power is observed, replace the ignition switch.
Test Starter Motor: If the starter does not engage, remove it from the vehicle. Bench test the starter motor; if it fails, replace it with a new one. Make sure to torque the mounting bolts to the manufacturer's specifications.

4. Fuel System

Fuel Pump Check: If the fuel pump does not activate, locate and replace the fuel pump relay if faulty. If the relay is good, inspect the fuel pump for proper operation and replace if necessary.

5. Reassemble and Test

Reconnect the battery terminal securely.
Start the engine to check if the issue is resolved.
