Solution

1. Preparation

Gather tools: wrench set, multimeter, battery cleaner, jumper cables, and load tester.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery using a wrench to prevent electrical shorts.
Sub-step 2: Clean the battery terminals with a battery cleaner to remove corrosion.
Sub-step 3: Reconnect the terminals securely.

3. Battery Testing

Sub-step 1: Use a multimeter to measure the voltage of the battery; replace the battery if voltage is below 12.6 volts.
Sub-step 2: Conduct a load test using a load tester; replace the battery if it fails the test.

4. Starter Inspection

Sub-step 1: Locate the starter motor, typically near where the engine and transmission meet.
Sub-step 2: Check the wiring and connections to the starter; clean and tighten as necessary.
Sub-step 3: If connections are good, test the starter motor by applying direct power to it; replace if it fails to engage.

5. Fuse and Relay Check

Sub-step 1: Locate the fuse box and check the starter relay and related fuses for continuity using a multimeter.
Sub-step 2: Replace any blown fuses or faulty relays with new ones.
