A month ago smelled gas really strong inside my car. Took to the shop 
and they said the fuel line was leaking in the engine. Prior to taking it 
into the shop when I tried to start the car it would crank but not turn 
over until 2-3 tries. Had fuel line replaced. Thought it would solve 
the cranking but not starting issues but it came back. I was due 
to have the spark plugs and fuel filter replaced so I did last week. 
Next day same starting issue. Usually happens after the car has 
sat for about an hour or two. Cranked but would not start until 
third try. Just got back from driving it and I see something leaking 
from around the gas tank. Pretty sure it is leaking fuel. 
  
So very frustrated and don't know what could be causing this. 
What should I have the shop check? Fuel pressure, obviously 
check leak. Not even sure if the starting issue is related to 
the fuel leak issue.
