Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, cleaning brush.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Inspect battery terminals for corrosion; clean if necessary.
If the battery voltage is low (below 12.4 volts), charge or replace the battery.
Reconnect the battery terminal after service.

3. Starter Relay Replacement

Locate the starter relay in the fuse box.
Remove the relay by pulling it straight out.
Install a new relay, ensuring it fits snugly into the socket.

4. Fuel System Check

Locate the fuel pump relay and fuse, and check them for continuity.
If the fuel pump is not working, replace it according to the service manual.
Inspect the fuel filter for clogs and replace if necessary.

5. Ignition Switch Replacement

Remove the steering column cover using a screwdriver.
Disconnect the wiring harness from the ignition switch.
Remove the ignition switch by unscrewing it from its housing.
Install the new ignition switch and reconnect the wiring harness.
Reassemble the steering column cover.
