Solution

1. Preparation

Gather tools: Multimeter, socket set, wrench set, battery terminal cleaner, safety gloves, and safety glasses.
Ensure the vehicle is in park or neutral and the parking brake is applied.

2. Battery Inspection

Sub-step 1: Disconnect the negative battery terminal using a wrench.
Sub-step 2: Clean any corrosion from the battery terminals with a terminal cleaner.
Sub-step 3: Reconnect the negative terminal and ensure it's tight.

3. Starter Relay and Fuse Check

Sub-step 1: Locate the fuse box and find the starter relay.
Sub-step 2: Swap the starter relay with another identical relay to test functionality.
Sub-step 3: Check the fuses associated with the starting system for continuity using a multimeter.

4. Starter and Wiring Inspection

Sub-step 1: Locate the starter motor, typically found near the transmission.
Sub-step 2: Check the wiring harness connected to the starter for any visible damage.
Sub-step 3: Use a multimeter to check for voltage at the starter solenoid when the ignition key is turned to the start position.

5. Starter Replacement (if necessary)

Sub-step 1: If the starter is faulty, disconnect the battery (negative terminal).
Sub-step 2: Remove the starter by unbolting it from its mount and disconnecting the electrical connectors.
Sub-step 3: Install the new starter by reversing the removal steps, ensuring all connections are secure.
