Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Address Fuel System Issues

Inspect the Fuel Pump:
- Locate the fuel pump (usually under the rear seat or in the trunk).
- Remove any access panels and disconnect the fuel pump connector.
- Test the fuel pump operation using a multimeter. Replace if faulty.
Replace Fuel Filter:
- Locate the fuel filter along the fuel line.
- Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the fuel lines and remove the old filter. Install the new filter, ensuring proper orientation.

3. Check Ignition Components

Inspect Spark Plugs:
- Remove the engine cover if necessary to access the spark plugs.
- Use a socket set to remove the spark plugs and inspect for wear or carbon buildup.
- Replace with OEM spark plugs if necessary, torque to manufacturer's specifications.
Test Ignition Coils:
- Disconnect the ignition coil connectors and remove the coils.
- Test each coil with a multimeter for proper resistance values. Replace any faulty coils.

4. Examine Air Intake System

Inspect Air Filter:
- Locate the air filter housing, remove the top cover, and inspect the air filter for dirt and blockages.
- Replace the air filter if dirty.
Clean MAF Sensor:
- Disconnect the MAF sensor connector and remove the sensor from the intake.
- Use MAF sensor cleaner to spray the sensor elements gently. Allow to dry before reinstalling.

5. Electrical System Check

Test Battery and Charging System:
- Use a multimeter to check the battery voltage (should be around 12.6 volts when fully charged).
- Start the vehicle and check the voltage again (should be between 13.7 to 14.7 volts). Replace the battery if it fails to hold charge.
