most likely bad coil pack or EGR issues...
Most automobiles will not start with a nonfunctioning coil pack. The coil pack will cause the spark plugs not to fire.

symptoms are: you can hear the engine missing, spitting and sputtering, loss of power...you can tell if it is a coil pack by unscrewing the spark plug that it connects to coil pack. when you look at your spark plug it should be a light grayish, white..this means the coil pack is working....it is best if you do this with new spark plugs, because your spark plugs could be bad. but you do this process until you find a bad plug then, that coil pack probably is the bad coil pack.
A bad coil pack would not smell like gasoline.
bad coil pack... replace coil pack
Then there is a no spark condition and engine will not run. If it has more than one coil pack it will miss on the cylinders controlled by the defective coil pack.
Bad coil or coil pack.
Check for fuel (bad fuel pump or clogged fuel filter) Check for spark (bad or weak ignition coil)
