Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Inspect and Replace Fuel Pump

Sub-steps:
1. Remove the fuel tank access cover if applicable, or lower the fuel tank.
2. Disconnect the fuel lines and electrical connectors from the fuel pump.
3. Remove the fuel pump assembly from the tank.
4. Install the new fuel pump assembly and reconnect the fuel lines and electrical connectors.
5. Reinstall the fuel tank and access cover.

3. Replace Ignition Components

Sub-steps:
1. Remove the ignition coil by disconnecting the electrical connector and unscrewing the mounting bolt.
2. Replace the ignition coil with a new one and secure it in place.
3. Remove the spark plugs using a socket set and inspect for wear or damage.
4. Replace any faulty spark plugs with new ones and torque them to the manufacturer's specifications (typically around 15-20 ft-lbs).

4. Test for Vacuum Leaks

Sub-steps:
1. Start the engine and use a smoke machine or carb cleaner to check for leaks around hoses and the intake manifold.
2. Repair or replace any damaged hoses or gaskets found during inspection.

5. Reconnect Battery and Test

Reconnect the battery after all repairs are completed.
Start the engine and allow it to idle to check for proper operation.
