Solution

1. Preparation

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

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety glasses, rags.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start) and observe the pressure reading.
If the pressure is below specifications (consult service manual for specific values), inspect the fuel pump and filter for blockages or failure.
Replace the fuel filter if clogged and if the fuel pump is faulty, replace it.

3. Ignition System Check

Tools Required: Socket set, torque wrench.
Remove the spark plugs using a socket.
Inspect the spark plugs for wear, cracks, or carbon buildup; replace if necessary.
Check the ignition coils for proper operation using a multimeter, replace if defective.
Reinstall spark plugs with the correct torque specifications as per the manufacturer’s manual.

4. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft brush, rags.
Remove the air intake duct from the throttle body.
Spray throttle body cleaner into the throttle body and clean with a soft brush to remove carbon buildup.
Wipe down with a rag and ensure the throttle plate operates freely.
Reassemble the air intake duct.

5. Sensor Testing

Tools Required: Multimeter.
Locate the crankshaft and camshaft position sensors.
Disconnect the electrical connectors and test resistance with a multimeter according to specifications found in the service manual.
Replace any faulty sensors.
