Have a fuel smell when 4runner is parked, not while driving. It drives fine but the check engine light and traction control light and vsc traction control lights. I just put it in the shop just wondering if it's the EVAP system maybe? And if I should've reset the computer before putting it in the shop? My wife took it to Autozone they put a scan tool on it. They said it had codes, no specific codes, referring to some part of the fuel system.

    I have the same thing right now. This came after a really heavy fuel smell and Toyota said I had a crack or nick in one of the fuel lines. They dropped the tank and repaired the problem for $650. and the fuel smell was not as bad but didn't go away. The three lights came on 3 days later. They said I have an emissions leak. Seems to me this was all one problem that should have been fixed. They didn't give me the code. Any thoughts?

    I have the same exact issue and my codes are p0440 & p0442. We have tried 2 new gas caps, replaced all the valves on the evap system including the canister, and replaced the filler neck on the tank. My mechanic knows there is a leak because the system won't hold a vacuum and the leak is so small it isn't showing up on a smoke tester. It runs GREAT and still gets good mileage. Please help, thanks
