2007 Pontiac G5 My car smells of gasoline

Smells problem
2007 Pontiac G5 4 cyl Automatic 65000 miles

My car has been smelling like gasoline for a while now. It smells even when it is not running but I have not noticed any leaks. I guess the smell is getting pretty strong becasue when people walk by my car in the parking lot they are smelling it.

Also, just recently it started having trouble starting up. I have to hold the key turned over for about 5-10 seconds for it to start up. Although if it has been driven recently it fires right up.
