Solution

1. Preparation

Gather tools and ensure the work area is clear.
Tools Required: Multimeter, socket set, OBD-II scanner, jumper cables.

2. Battery Inspection and Replacement

Sub-step 1: Disconnect the negative (-) battery terminal first, followed by the positive (+) terminal to ensure safety.
Sub-step 2: Remove the battery from the vehicle.
Sub-step 3: Clean the battery terminals using a wire brush if there is corrosion.
Sub-step 4: Test the battery with a multimeter and replace it if voltage is below 12.6 volts.
Sub-step 5: Reinstall the new or cleaned battery, connecting the positive (+) terminal first, then the negative (-) terminal.

3. Ignition Switch Replacement

Sub-step 1: Remove the steering column covers using a screwdriver.
Sub-step 2: Locate the ignition switch and disconnect the wiring harness.
Sub-step 3: Unscrew the ignition switch from its position and replace it with a new switch.
Sub-step 4: Reconnect the wiring harness and reassemble the steering column covers.

4. Starter Motor Inspection and Replacement

Sub-step 1: Disconnect the battery again for safety.
Sub-step 2: Remove the starter motor by unscrewing it from its mounting bracket.
Sub-step 3: Test the starter by applying direct voltage from the battery; if it does not engage, replace the starter motor.
Sub-step 4: Install the new starter motor and reconnect the battery.

5. Fuel System Check

Sub-step 1: Check the fuel pump fuse and relay for continuity; replace if faulty.
Sub-step 2: Inspect the fuel lines for leaks or blockages.
Sub-step 3: Use a fuel pressure gauge to verify that the fuel pump is delivering adequate pressure; replace the pump if pressure is low.
