Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before proceeding with repairs.

2. Inspect the Battery

Tools Required: Multimeter, wrench set
Check the battery voltage with a multimeter; it should be above 12.4 volts.
Clean battery terminals with a wire brush and re-tighten connections.
If the battery voltage is low, replace the battery with a compatible unit.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety glasses
Locate the fuel pump access panel (if applicable) or the fuel line.
Connect the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position (do not start the engine).
Check that fuel pressure is within the manufacturer's specifications (typically around 50-60 psi for XC60).
If pressure is low, replace the fuel pump or check for clogged fuel filters.

4. Ignition System Check

Tools Required: Socket set, spark plug socket
Remove spark plugs and inspect them for wear or fouling. Replace if necessary.
Test ignition coils with a multimeter according to manufacturer specs; replace any that are faulty.
Reinstall spark plugs and coils after inspection.

5. Fuel Injector Assessment

Tools Required: Injector cleaner or replacement injectors
If fuel injectors are suspected to be clogged, use an injector cleaning solution or replace them.
Reconnect all components after cleaning or replacement.
