Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrenches, and battery terminal cleaner.
Ensure safety: Wear gloves and safety glasses, and keep a fire extinguisher nearby.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative terminal of the battery using a socket wrench.
2. Clean the battery terminals and connectors with terminal cleaner.
3. Reconnect the battery terminals securely (positive first, then negative).

3. Starter and Ignition Check

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Use a multimeter to test for voltage at the starter. If no voltage, trace back to the ignition switch.
3. If the starter is faulty, remove it by disconnecting the wiring and unbolting it from the engine.

4. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and check for continuity using a multimeter.
2. If the relay is functioning, check the fuel pump by removing the access cover (if applicable) or inspecting the fuel lines.
3. Replace the fuel pump if it is not functioning properly.

5. Reassemble and Test Start

Sub-steps:
1. Reconnect all components in reverse order.
2. Reconnect the battery and ensure all connections are tight.
3. Attempt to start the vehicle.
