Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Fuel System Inspection

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (without starting the engine) to check fuel pressure. It should be within the manufacturer's specified range (typically around 50-60 psi).
3. If fuel pressure is low, inspect the fuel pump and fuel filter for obstructions or failures.
4. Replace the fuel pump or filter if necessary, following the vehicle's service manual for specific instructions.

3. Ignition System Check

Sub-steps:
1. Remove the spark plugs using a spark plug socket and inspect for wear or fouling.
2. Test the ignition coils with a multimeter to ensure they are functioning correctly.
3. Replace any faulty spark plugs or ignition coils.
4. Reassemble the ignition components and reconnect the battery.

4. Air Intake System Inspection

Sub-steps:
1. Remove the air filter and inspect for dirt or obstruction.
2. Clean or replace the air filter as required.
3. Inspect the intake hoses for cracks or disconnections, replacing them if necessary.

5. Electrical System Verification

Sub-steps:
1. Use a multimeter to check the battery voltage; it should read around 12.6 volts when the engine is off.
2. Start the engine and check the alternator output; it should be between 13.7 to 14.7 volts.
3. Replace the battery or alternator if any issues are identified.
