Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Fuel System Inspection

Check Fuel Pump:
- Reconnect the battery.
- Turn the ignition key to the 'on' position without starting the engine to activate the fuel pump.
- Listen for the pump's humming sound.
Test Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail service port.
- Start the engine (or crank if it doesn't start) and check the pressure reading.
- If pressure is below specifications, replace the fuel pump.

3. Ignition System Check

Inspect Spark Plugs:
- Remove spark plug wires or ignition coils.
- Take out the spark plugs and inspect for carbon buildup or wear.
- Replace any worn or fouled spark plugs with OEM recommended types.
Test Ignition Coils:
- Use a multimeter to check coil resistance against manufacturer specifications.
- Replace any faulty ignition coils.

4. Air Intake System Inspection

Inspect Air Filter:
- Remove the air filter housing cover.
- Check the air filter for dirt and debris; replace if necessary.
Check for Leaks:
- Visually inspect all intake hoses and connections for cracks or disconnections.
- Replace any damaged hoses.
