White smoke from tailpipe. Not leaking of oil or coolants and runs fine.  Have notices very
small hesitation once or twice. Appears to be a a lot of white smoke when you first start

Can't be head gaskets, nothing leaking at all, watching levels very closely.

Sound,s like the car may just be loading up on fuel when you first crank it,giving you the fuel smoke,then burns off,may need to have injector,s cleaned,and run a little fuel treatment through it,if no other fluid is being lost,

The back fire is,saying there is to much fuel,could all so be fuel pressure regulator of bad injector.,if the above does not help.

Will have that checked, one can only hope it's that simple.
