2003 Nissan Altima Stong fuel smell left rear wheel well

Smells problem
2003 Nissan Altima 4 cyl Automatic 52,000 miles

We have reciently noticed a fuel smell at the left rear wheel of the auto. The engine light does not come on. When you remove the gas cap you hear noise from the fuel cell. I have replaced the gas cap, raised the car and checked for leaks, found none.
Is there a way to inspect the soft link on top of the fuel cell without dropping the tank. I think the soft link may have a crack, or I may have a fuel pump problem.
One more symptom, the engine does not always start with the first attempt but always the second time.
Looking for help as I am not working and can't afford an expensive auto repair.
