Q.What Is Wrong With My New Guenia Impatiens? They Aren’t Flowering And Perhaps Have Some Sort Of Fungus?
Deer have eaten some and I sprayed deer scram. They all were blooming when planted and there are buds in some but only a few flowering now. Overwatering ? Not enough sun? Fungus ?

Pinch out all the brown and yellow leaves. New Guinea impatiens need moist soil so you probably aren't overwatering unless the plants are in shade. Is the soil well draining? If not, the roots may be sitting in water and causing some root rot issues. Let the plants dry out a bit before watering again.
They also need about half a day of sun; morning sun is best. Here are their best care tips that should help identify where to improve.
I have better luck with sunpatiens, which can take much more sun than impatiens.
