ok that should work

 

Im having the same issue. i know flooding is common but from what i hear the longer it sits thee the longer it would give my fuel injectors time to leak onto the rotor, but to me the opposite is happening. If i park it the longer it sits the better off I am. Everytime i walk outside in the morning to start it she gives me no problems, but sure enough if i drove her an hour ago she might flood on me, and it also seems to be more likely to happen the colder or the more humid it is. One lil trick i have learned (and i have an s4) is to floor it for a few seconds before cranking it and then cranking her over and then for some reason i have a little bit more momentum heading into a start where she almost floods out but starts anyhow. Any reasoning for this?
