Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection

Sub-step 1: Use a multimeter to measure the battery voltage; it should be around 12.6 volts or more.
Sub-step 2: Clean the battery terminals with a wire brush to remove corrosion.
Sub-step 3: If the battery voltage is low, recharge the battery or replace it if it's over three years old.

3. Starter Motor Check

Sub-step 1: Reconnect the battery and use a multimeter to check voltage at the starter motor while someone turns the key to the start position.
Sub-step 2: If voltage is present but the starter does not engage, remove the starter for inspection.
Sub-step 3: Test the starter motor by connecting it directly to the battery. If it fails to operate, replace the starter.

4. Fuel System Inspection

Sub-step 1: Turn the ignition to the "ON" position without starting the engine to listen for the fuel pump priming.
Sub-step 2: Use a fuel pressure gauge to check for proper fuel pressure according to manufacturer specifications.
Sub-step 3: Replace the fuel pump or filter if pressure is inadequate.

5. Ignition System Check

Sub-step 1: Remove and inspect spark plugs for wear or fouling; replace if necessary.
Sub-step 2: Test ignition coils for resistance using a multimeter, replacing any that are out of specification.
