Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery for safety.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Check the fuel pump function:
- Locate the fuel pump relay and test its operation.
- Use the fuel pressure gauge to measure the fuel pressure; it should be within the manufacturer's specifications (typically 30-50 psi).
- If pressure is low, inspect and replace the fuel filter and/or fuel pump as necessary.

3. Air Intake System

Tools Required: Screwdriver set, flashlight.
Inspect the air filter and intake manifold:
- Remove the air filter and check for dirt or blockages; replace if necessary.
- Examine the intake manifold for any cracks or loose connections.

4. Electrical System Check

Tools Required: Multimeter.
Measure battery voltage:
- Connect the multimeter to the battery terminals; a healthy battery should read around 12.6 volts when off and 13.7 to 14.7 volts when running.
- Inspect and replace any corroded terminals or damaged wiring.

5. Ignition System Inspection

Tools Required: Spark plug socket, torque wrench.
Inspect spark plugs and ignition coils:
- Remove the spark plugs and evaluate their condition (look for wear, carbon buildup, or oil contamination).
- Replace any faulty spark plugs and check the ignition coils for proper operation.
