Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, spark tester.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery, ensuring terminals are tight and free of corrosion.
2. If the battery voltage is low, charge or replace the battery.
3. Retest the voltage after connecting.

3. Ignition Switch Testing

Sub-steps:
1. Remove the steering column cover using a screwdriver.
2. Locate the ignition switch and disconnect the wiring harness.
3. Using a multimeter, check for continuity while turning the key to the 'Start' position.
4. If there's no continuity, replace the ignition switch.

4. Fuel System Check

Sub-steps:
1. Access the fuel pump relay in the fuse box.
2. Swap the fuel pump relay with another relay of the same type to test functionality.
3. If the fuel pump does not engage, check the fuel pump fuse and replace if necessary.
4. If the pump is still silent, it may need to be replaced.

5. Spark Check

Sub-steps:
1. Remove a spark plug wire from one of the ignition coils.
2. Insert a spark tester into the wire and ground it to the engine.
3. Crank the engine and observe for a spark; if no spark is present, the ignition coil may need replacement.
4. Repeat for each ignition coil if necessary.
