Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Connect the fuel pressure gauge to the fuel rail service port.
3. Turn the ignition to the "On" position without starting the engine to check fuel pressure.
4. If pressure is below specifications (typically 30-45 psi), replace the fuel pump.
Tools Required: Fuel pressure gauge, socket set.

3. Ignition System Check

Sub-steps:
1. Remove the spark plugs using a spark plug socket.
2. Inspect spark plugs for wear or carbon buildup; replace if necessary.
3. Test ignition coils with a multimeter; replace any faulty coils.
Tools Required: Spark plug socket, multimeter.

4. Air Intake and Vacuum System

Sub-steps:
1. Remove and inspect the air filter; clean or replace as necessary.
2. Check all vacuum hoses for cracks or disconnections.
3. Replace any damaged hoses to ensure proper airflow.
Tools Required: Screwdrivers, pliers.

5. Battery and Charging System

Sub-steps:
1. Use a multimeter to check the battery voltage; it should be around 12.6 volts.
2. Test the alternator output; it should be between 13.7-14.7 volts when the engine is running.
3. Replace the battery or alternator if readings are outside specifications.
Tools Required: Multimeter.
