Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Tools Required: OBD-II scanner, fuel pressure gauge, socket set.
Check the fuel pressure with a gauge connected to the fuel rail. It should match the manufacturer's specifications (typically around 30-40 PSI).
If the pressure is low, replace the fuel pump.

3. Fuel Filter Replacement

Remove the old fuel filter:
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the fuel lines from the filter using appropriate tools.
Install the new fuel filter in the correct orientation.
Reconnect fuel lines securely.

4. Air Intake System Inspection

Inspect the air filter for dirt or blockages and replace it if necessary.
Check the intake manifold for vacuum leaks. Use a smoke test if needed for thorough detection.

5. Battery and Charging System Check

Use a multimeter to check for at least 12.6 volts with the engine off and around 13.7-14.7 volts with the engine running.
If voltage is outside these ranges, consider replacing the battery or alternator.
