Solution

1. Preparation

Gather tools including a multimeter, OBD-II scanner, and basic hand tools.
Ensure the vehicle is in a well-ventilated area and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Battery and Electrical System Check

Sub-step 1: Reconnect the battery and check voltage again. If below 12.4 volts, charge or replace the battery.
Sub-step 2: If the battery is good, inspect battery terminals for corrosion and clean if necessary.

3. Inspect and Replace Fuses

Sub-step 1: Locate the fuse box (typically under the dashboard or in the engine compartment).
Sub-step 2: Identify and remove the fuses related to the starting system and inspect them.
Sub-step 3: Replace any blown fuses with the same amperage rating.

4. Key Fob and Security System

Sub-step 1: Verify that the key fob battery is functional; replace it if necessary.
Sub-step 2: If the key fob is functional, check the vehicle’s security system; refer to the owner’s manual for reset procedures if needed.

5. Fuel System Inspection

Sub-step 1: If the fuel pump isn't audible, check the fuel pump relay by swapping it with a similar one in the fuse box.
Sub-step 2: If the relay is functional, consider testing the fuel pump with a fuel pressure gauge to ensure it is delivering fuel as required.

6. Ignition System Inspection

Sub-step 1: Remove spark plug wires and inspect for damage; replace as necessary.
Sub-step 2: Test ignition coils using a multimeter to ensure proper resistance values, replacing any faulty coils.
