Smell gas is bad but no leaks car backfired now i have very bad mpg and gas smell

Stop using it

Has to be diagnosed & repaired

What codes if any are stored in the ecm/pcm (computer)

Back fire could be a lean condition

The gas condition could be a leaking injector
or an evap system problem

Hard to tie all the issues together without the car
& some testing or checking of things & a road test

You may have a timing chain issue, as I believe they
may have problems there,have to check bulletins on that

I smell gas after a hard start inside my camaro.....every time

You may smell the fumes as the motor may be getting flooded, I know most people think this can't happen with fuel injection, but if there's a igntion problem, yes it can. [ you may want to do a tune-up = plugs wires etc.] . If you have a hard start, hold the gas pedal to the floor and crank the engine. The computer will go into a CLEAR FLOOD mode reducing the amount of fuel from the injectors to help it start. You may also have the coolant tempature sensor checked, as this will sometimes cause a starting problem.
