Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
1. Clean any corrosion from the battery terminals using a wire brush.
2. Tighten battery terminal connections to ensure a solid contact.
3. If the battery voltage is low, jump-start the vehicle or replace the battery if it fails load testing.

3. Starter Relay Check

Sub-steps:
1. Locate the starter relay in the fuse box.
2. Swap the starter relay with another relay of the same type.
3. Attempt to start the engine again. If it starts, replace the faulty relay.

4. Starter Inspection

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use a multimeter to check for voltage at the starter solenoid while a helper turns the ignition key.
3. If voltage is present but the starter does not engage, remove the starter.
4. Inspect the starter for damage and perform a bench test to confirm functionality.
5. If faulty, replace the starter with a new or refurbished unit.

5. Reassembly and Final Checks

Sub-steps:
1. Reconnect all cables and ensure they are tight.
2. Reinstall the starter and secure it with the appropriate torque specification.
3. Reconnect the negative battery terminal and ensure all components are reinstalled properly.
