Toyota Repair/Vapor lock?


I have a 2008 Avalon with 49,000 miles. About 6 months ago I couldn't start it. I called AAA and it turned out to be what the AAA guy called something like vapor lock. He floored the gas pedal and turned the key and it started. The same thing happened to me yesterday when I picked up my car from an airport parking lot. The attendant retrieved my car but when I tried to start it, it wouldn't start. I did the same thing the AAA guy did; floored the gas pedal and it worked. Can you tell me what the problem is?

Hello, vapor lock is something that cars with carburetors did before the 1980's so it would be extremely unusual for an EFI controlled engine do have this problem especially one of this age.
At this time I will agree that it is most likely fuel related so if the check engine light does not turn on when the engine is running I would recommend that you try first to have the throttle body cleaned and do a fuel injector cleaning service, try adding a can of fuel treatment in the fuel tank.
