Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect Fuel System

Fuel Pump Check:
- Reconnect the battery.
- Turn the ignition to "ON" (do not start) and listen for the fuel pump.
- If no sound is heard, proceed to replace the fuel pump.
Fuel Pressure Test:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to "ON" and observe the gauge reading.
- If the pressure is below specifications, check for a clogged fuel filter or replace the pump.

3. Address Fuel Line Issues

Visually inspect the fuel lines for any signs of cracks or leaks.
If leaks are found, replace the affected fuel lines immediately.

4. Check and Replace Fuel Filter

Locate the fuel filter (consult the service manual for location).
Use a socket set to disconnect the fuel lines from the filter.
Replace the old filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and secure them properly.

5. Reassemble and Test

Reconnect the negative battery terminal.
Start the vehicle to verify if it starts correctly.
