Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery cable to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Clean the battery terminals with a battery terminal cleaner.
3. Check the voltage of the battery using a multimeter; it should read above 12.4 volts.
4. If the battery voltage is low, charge or replace the battery with a new one (ensure it matches OEM specifications).

3. Starter Motor Inspection

Sub-steps:
1. Remove the starter motor from the vehicle (typically requires removing the mounting bolts).
2. Bench test the starter motor by connecting it directly to a battery; check for proper operation.
3. If the starter does not engage or produces a clicking noise, replace the starter motor.
4. Reinstall the starter motor, ensuring all connections are tight.

4. Fuel System Check

Sub-steps:
1. Turn the ignition to the "ON" position (without starting the engine) and listen for the fuel pump priming.
2. If no sound is heard, check the fuel pump fuse and relay; replace if necessary.
3. If the fuel pump is faulty, replace it according to the manufacturer's specifications.
4. Reconnect battery terminals and ensure all connections are secure.

5. Ignition Switch and Wiring Inspection

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Inspect the ignition switch for any signs of wear or damage.
3. Use a multimeter to test the switch for continuity when the key is turned to the "start" position.
4. Replace the ignition switch if it fails the continuity test.
