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 battery terminal to ensure safety.

2. Address Fuel System Issues

Inspect Fuel Lines:
- Use a flashlight to check for visible leaks or cracks in the fuel lines.
- If any leaks are found, replace the damaged section of the fuel line.
Test Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the ON position (without starting the engine) and check if the pressure meets specifications.
- If pressure is low, replace the fuel pump or filter as needed.

3. Inspect and Replace Ignition Components

Remove Spark Plugs:
- Use a socket wrench to remove the spark plugs.
- Inspect each plug for wear, carbon buildup, or damage. Replace if necessary.
Check and Replace Ignition Coils:
- Disconnect the wiring harness from each ignition coil.
- Remove the ignition coils using a socket wrench.
- If coils show signs of failure, replace them.

4. Reassemble and Reconnect

Reinstall all components in reverse order.
Ensure all connections are secure and there are no loose wires.
Reconnect the negative battery terminal.
