Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required: OBD-II scanner, socket set, multimeter, screwdriver set, cleaning supplies.

2. Address Fuel System Issues

Inspect Fuel Pump:
1. Access the fuel pump area, usually located under the rear seat or in the trunk.
2. Check for proper voltage to the pump using a multimeter.
3. If the pump is faulty, replace it. Use a new fuel pump assembly compatible with the XC60.
Replace Fuel Filter:
1. Locate the fuel filter along the fuel line.
2. Disconnect the fuel lines safely, ensuring to relieve fuel pressure first.
3. Replace the old filter with a new one, ensuring correct orientation.

3. Check Ignition System

Inspect Spark Plugs:
1. Remove the spark plug wires and unscrew the spark plugs using a socket.
2. Inspect for wear or carbon buildup; replace if necessary with OEM specifications.
Test Ignition Coils:
1. Use a multimeter to check resistance in each ignition coil.
2. Replace any coils that do not meet manufacturer specifications.

4. Clean Throttle Body and Mass Airflow Sensor

Throttle Body Cleaning:
1. Remove the air intake duct to access the throttle body.
2. Use throttle body cleaner and a soft cloth to remove carbon deposits.
Mass Airflow Sensor Cleaning:
1. Disconnect the MAF sensor electrical connector.
2. Spray MAF cleaner on the sensor element without touching it.

5. Reconnect Battery

Reconnect the negative battery terminal once all repairs and inspections are complete.
