Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, basic hand tools.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position without starting the engine and check the fuel pressure reading.
- Compare the reading with manufacturer specifications.
If pressure is low, replace the fuel pump.

3. Ignition System Repair

Tools Required: Socket set, torque wrench, multimeter.
Remove the ignition coil and inspect for damage or corrosion.
Use a multimeter to test the resistance of the spark plugs and ignition coils. Replace any faulty components.
Reinstall all components securely, ensuring proper torque specifications are met.

4. Air Intake System Check

Tools Required: Screwdriver set, vacuum gauge.
Remove the air intake duct and inspect the air filter for dirt and blockages.
Clean or replace the air filter as necessary.
Check the intake manifold and hoses for leaks and ensure all connections are tight.

5. Electrical Connection Examination

Tools Required: Multimeter, wire brush.
Inspect battery terminals for corrosion and clean if necessary.
Test the alternator output to ensure it is charging the battery correctly.
Repair or replace any damaged wiring or connectors.
