Solution

1. Preparation

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

2. Fuel System Inspection

Fuel Tank and Lines:
- Raise the vehicle using a jack and secure with jack stands.
- Visually inspect the fuel tank and lines for cracks or wet spots where fuel may be leaking.
- If a leak is found, replace the damaged line or tank as needed.
Fuel Cap:
- Remove the fuel cap and inspect the rubber seal for damage or debris.
- Clean the seal and the fuel filler neck with a cloth. If damaged, replace the fuel cap.

3. Fuel Injector Check

Locate the fuel injectors on the engine.
Remove the electrical connectors carefully.
Inspect each injector for signs of fuel leakage.
If any injector is leaking, replace the faulty injector.

4. Fuel Pressure Testing

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) to pressurize the system.
Check the gauge reading; it should match the manufacturer's specifications.
If pressure is too high or low, investigate further into the fuel pump or regulator.

5. Reassemble and Test

Reconnect all components, including the negative battery terminal.
Start the vehicle and check for any signs of leaks.
Monitor the engine for smooth operation and ensure no gasoline odor persists.
