Q.Why doesn’t my pomegranate turn red inside?
My trees are about 8-10 yrs old and have only had 1 piece of fruit turn red on the inside……..They look completely normal on the out side but the fruit inside is basically white?

Did you purchase the tree, or was this planted from seed. If this is from seed, then that would explain the issue. They aren't true from seed, and will have lots of variation, including undesirable fruit.
If this was bought as an established tree, then it could be likely that it is underfertilized. This article will give you more information on the care of these: https://www.gardeningknowhow.com/edible/fruits/pomegranate/fertilizer-for-pomegranates.htm
