Solution

1. Preparation

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

2. Address Faulty Fuel System

Check Fuel Pressure: Use a fuel pressure gauge to measure the pressure at the fuel rail.
- Tools Required: Fuel pressure gauge.
- Sub-step: If pressure is below specifications, replace the fuel pump or fuel filter.
Inspect Fuel Lines: Check for any visible leaks or damage along the fuel lines.
- Sub-step: Replace any damaged sections.

3. Repair Ignition System

Replace Spark Plugs: Remove and inspect spark plugs for wear or fouling.
- Tools Required: Socket set, torque wrench.
- Sub-step: Replace with OEM-spec plugs and torque to manufacturer specifications.
Test Ignition Coils: Use a multimeter to check the resistance of each coil.
- Sub-step: Replace any faulty ignition coils.

4. Clean Air Intake System

Inspect and Clean Throttle Body: Remove the throttle body and clean it using throttle body cleaner.
- Tools Required: Screwdriver set, throttle body cleaner.
- Sub-step: Reinstall the throttle body and ensure all connections are secure.
Replace Air Filter: Remove the air filter and inspect for dirt and blockages.
- Sub-step: Replace with a new OEM air filter.

5. Electrical System Check

Test Battery and Alternator: Use a multimeter to check the battery voltage and alternator output.
- Sub-step: Replace the battery if the voltage is below 12.4 volts or the alternator if it’s not charging.
