Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Ensure the vehicle is parked on a flat surface and the engine is off. Disconnect the negative battery terminal for safety.

2. Battery Inspection

Sub-steps:
- Use a multimeter to measure the battery voltage; it should be above 12.4 volts.
- Clean battery terminals with a battery terminal cleaner to ensure good connections.
- If the battery voltage is low, recharge or replace the battery as needed.

3. Ignition Switch Testing

Sub-steps:
- Remove the steering column covers using a socket set.
- Locate the ignition switch and disconnect the electrical connector.
- Use a multimeter to check for continuity between terminals when the key is turned to the 'On' position.
- If there is no continuity, replace the ignition switch.

4. Starter Motor Inspection

Sub-steps:
- Locate the starter motor and inspect its connections for corrosion or looseness.
- Use a multimeter to test the voltage at the starter motor when the key is turned to the start position.
- If there is no voltage or the starter is unresponsive, replace the starter motor.

5. Fuel System Check

Sub-steps:
- Locate the fuel pump fuse in the fuse box and check for continuity.
- If the fuse is good, listen for the fuel pump operation while turning the key to the 'On' position (not starting).
- To check fuel pressure, use a fuel pressure gauge connected to the fuel rail. It should meet manufacturer specifications.
- Replace the fuel pump if it is not operational or if fuel pressure is inadequate.

6. Spark Plug and Ignition Coil Inspection

Sub-steps:
- Remove the spark plugs and inspect them for wear or fouling.
- Replace any damaged spark plugs (torque to manufacturer specifications).
- Test each ignition coil for resistance using a multimeter; replace any defective coils.
