Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection and Replacement

Sub-step 1: Inspect the battery terminals for corrosion; clean if necessary using a battery terminal cleaner.
Sub-step 2: If the battery voltage is below 12.4 volts, charge or replace the battery.
Sub-step 3: Reconnect the battery terminals securely after cleaning or replacing the battery.

3. Starter Relay and Fuse Check

Sub-step 1: Identify the starter relay in the fuse box (refer to the owner’s manual for location).
Sub-step 2: Remove the starter relay and test it with a multimeter for continuity.
Sub-step 3: Replace any blown fuses associated with the starting system.

4. Starter Motor Inspection

Sub-step 1: Locate the starter motor (typically found near the engine block).
Sub-step 2: Check for loose or damaged wiring connections to the starter motor.
Sub-step 3: If necessary, remove the starter motor for testing; bench test it to verify functionality.
Sub-step 4: If the starter is faulty, replace it with a new or refurbished unit, ensuring to torque the mounting bolts to manufacturer's specifications.
