Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, fuel pressure gauge, funnel, fresh gasoline, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Add Fuel

Open the fuel filler cap and insert a funnel.
Pour in fresh gasoline (at least 2-3 gallons) to ensure sufficient fuel in the tank.

3. Prime the Fuel System

Turn the ignition to the "ON" position without starting the engine.
Listen for the fuel pump to prime (a humming sound) for a few seconds.
Turn the ignition off and repeat the ON position two more times to ensure the fuel system is pressurized.

4. Start the Engine

Attempt to start the engine. If it does not start, proceed to the next step.
If it does start, monitor for any unusual sounds or performance issues.

5. Check Fuel Pump and Relay

If the engine does not start, locate the fuel pump fuse in the fuse box.
Remove the fuse and inspect it for continuity using a multimeter.
If blown, replace it with the correct amperage fuse.
Check the fuel pump relay for proper operation by swapping it with a similar relay in the fuse box (if available).

6. Inspect Fuel Pressure

Connect the fuel pressure gauge to the fuel rail service port.
Turn the ignition to the “ON” position and check the pressure; it should be within the manufacturer’s specifications.
If pressure is low or nonexistent, the fuel pump may need replacement.
