Solution

1. Preparation

Gather tools and parts: multimeter, socket set, OBD-II scanner, fuel pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Battery Inspection

Disconnect Battery: Disconnect the negative terminal first, followed by the positive terminal.
Clean Terminals: Use a wire brush to clean any corrosion from the battery terminals and connectors.
Test Battery: Use a multimeter to measure voltage; it should read above 12.4 volts. If below, replace the battery.

3. Starter Motor Check

Reconnect Battery: Reconnect the battery terminals securely.
Test Starter: Use a multimeter to check voltage at the starter motor terminal while someone turns the ignition key.
Replace Starter: If the voltage is adequate but the starter does not engage, replace the starter motor.

4. Fuel System Check

Check Fuel Pump: Turn the ignition key to the "on" position without starting the engine and listen for the fuel pump activation sound.
Test Fuel Pressure: Connect a fuel pressure gauge to the fuel rail and check that the pressure meets manufacturer specifications. If pressure is low, replace the fuel pump.

5. Ignition System Review

Inspect Spark Plugs: Remove spark plugs and check for wear or fouling. Replace if necessary.
Check Ignition Coils: Test ignition coils for functionality using a multimeter as per manufacturer specifications.
