my Toyota Corolla E140 (2006-2013) has a strong fuel smell what should I do

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues.

2. Inspect Fuel Lines

• Use a socket set to remove any protective covers if necessary.
• Visually inspect the fuel lines from the fuel tank to the engine bay for cracks or leaks.
• If leaks are found, replace the damaged fuel lines with OEM or high-quality aftermarket replacements.

3. Check Fuel Injectors

• Remove the engine cover if applicable.
• Inspect the fuel injectors for signs of fuel leaking around the seals.
• If leaking is detected, replace the injector seals or the entire injector assembly if needed.

4. Examine Fuel Tank

• Safely lift the vehicle using a jack and secure it with jack stands.
• Inspect the fuel tank for rust, punctures, or damage.
• If damage is found, replace the fuel tank as necessary.

5. Check Fuel Pressure Regulator

• Locate the fuel pressure regulator (usually on the fuel rail).
• Disconnect the vacuum line and check for fuel leakage.
• If leaking, replace the fuel pressure regulator.

6. Inspect Charcoal Canister

• Locate the charcoal canister, typically near the fuel tank.
• Check for cracks or damage and ensure all hoses are properly connected.
• Replace the charcoal canister if any damage is found.
