AnswerHi Steffanie,
Vapor locking only happens if the fuel lines get very very hot, like from the exhaust system, and boil the gas inside the line, forming a big bubble of vapor, which acts like a spring in the line, not allowing the pump to move fuel.
I sincerely doubt yours is vapor locking.
But it is possible there is an injector leaking, and flooding the engine.
Depending on what type of injection system it has, it could be fairly easy to check, or quite involved.
Fuel pressure testing is something else that might need done.
But that smell is from raw gas flooding the engine, and it could be creating a fire hazzard, so get it checked out pretty soon.
The hour wait is the time required for the gas to evaporate, so there must be a pretty large amount involved, and your comment about eating a lot of gas also sounds like that.
