Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, basic hand tools.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery to prevent electrical shocks while working.

2. Diagnose Engine Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "on" position without starting the engine.
Retrieve and note any error codes that may indicate specific issues.

3. Inspect and Replace Ignition Components

Ignition Coils:
- Remove engine cover (if applicable) using a socket set.
- Disconnect the electrical connector from each ignition coil.
- Use a multimeter to test each coil for proper resistance.
- Replace any faulty ignition coils with new ones, torque to manufacturer's specifications.
Spark Plugs:
- Remove spark plugs using a socket wrench.
- Inspect for wear or damage; replace if necessary.
- Gap new spark plugs to the manufacturer’s specification and install, torquing to the specified values.

4. Check Fuel Delivery

Attach a fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position to prime the fuel system, then check the pressure reading.
If the pressure is below specifications, replace the fuel pump or filter as needed.

5. Clear Codes and Test Drive

After replacing any faulty components, reconnect the battery.
Use the OBD-II scanner to clear any trouble codes.
Start the engine and perform a test drive to ensure the issue is resolved.
