Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, battery charger.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect the battery terminals for corrosion and clean them using a wire brush.
If the battery is low, charge it fully using a battery charger.
Test the battery voltage with a multimeter; it should read around 12.6 volts or more.
If the battery is faulty (below 12.4 volts after charging), replace it with a new, compatible battery.
- Torque Specification: Ensure terminal connections are tightened to 10-15 Nm.

3. Fuel System Check

Ensure there is adequate fuel in the tank.
Listen for the fuel pump priming when the ignition is turned on.
If the fuel pump is not operating, check the fuel pump relay and fuse.
If necessary, replace the fuel pump according to the manufacturer’s specifications.

4. Starter Motor and Ignition System

Inspect wiring to the starter motor for any loose connections or corrosion.
Test the starter motor by applying direct battery voltage to it; if it does not engage, replace the starter motor.
Check spark plugs for wear and replace if necessary. Ensure the gap is set to the manufacturer’s specifications.
Inspect and test ignition coils for proper function; replace if faulty.

5. Reassembly

Reconnect the battery negative terminal after all repairs are completed.
Start the vehicle to ensure all components are functioning properly.
