Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, wrenches), screwdriver.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the battery negative terminal to avoid electrical hazards.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect battery terminals and clean any corrosion using a wire brush.
2. Tighten loose connections securely.
3. If the battery voltage is below 12.4 volts, jump-start the vehicle or replace the battery.
Safety Warning: Ensure all electrical components are off before reconnecting the battery.

3. Starter Motor and Relay Check

Sub-steps:
1. Locate the starter relay in the fuse box (consult the owner's manual for exact location).
2. Swap the starter relay with a similar relay (such as the horn relay) to test functionality.
3. If the starter does not engage, remove the starter motor for further testing.
4. Test the starter motor with a direct connection to the battery using jumper cables.
Tools Required: Jumper cables.

4. Fuel System Inspection

Sub-steps:
1. Verify that the fuel pump fuse is intact; replace if necessary.
2. Check the fuel pump relay; test it similarly to the starter relay.
3. If the fuel pump is not functioning, replace it as per manufacturer specifications.
Safety Warning: Be cautious of fuel spillage; work in a well-ventilated area.

5. Ignition System Check

Sub-steps:
1. Check for spark by removing a spark plug, reconnecting it to the ignition coil, and cranking the engine.
2. If no spark is present, inspect the ignition coil and replace if faulty.
3. Inspect the ignition switch and wiring for damage, and replace the switch if necessary.
