I have a wisteria tree that is 3 yrs. old and has braided trunk. Does it need support to climb or can it be free standing to climb? How to prune and when?
Your Wisteria will need to be trained onto a sturdy support. It is not recommend to attach it to your house siding.
Here are a couple links for you.
We have grown 2 different vines and they are in full sun and we keep them pruned. They have not bloomed. One of them not at all and it has been planted for 5 years and the other has not bloomed for 2 years.
Was your wisteria bought at the nursery or grown from seed? Wisteria grown from seed can take up to 15 years to bloom, as incredulous as that sounds.
The following article details the reasons for non-blooming wisteria and offers suggestions to remedy it:

Does the wisteria develop buds that just aren’t opening? If so, this article will help you:

Why does my 2 year old wisteria plant look like it's dying directly after replanting? Yesterday we dug up our smallish wisteria plant that was in bloom, carefully taking as much root and soil as possible. But as soon as we replanted it, it looked like it was dying and there has been no change today. Many thanks. Laura
Any kind of move or transplant is a shock to a plant’s system and it takes a period of time to recover. Here is an article on transplant shock that will give you guidelines on how to soothe the transition for your plant:

The best time to transplant wisteria is actually in the late fall or early spring when the plant is dormant. And, just to give you a heads up, established wisteria do not like to be moved and may rebel by not blooming for several years.

Thankyou for your advice, greatly appreciated
My wisteria started out normal this spring with many flowers. All of a sudden it has stopped growing and the leaves are are curling and dry. What causes this and what can I do? I have 4 wisterias here and none of the others are having this issue. It is getting plenty of water. Thanks.
Here is an article that will help you diagnose your problem - I suspect your one wisteria has a pest issue.

The leaves on my wisteria vine are turning yellow and then dying. It is blooming and the flowers look great, but only the newer leaves are green. Is it getting too much water?
When older leaves turn yellow while the younger leaves are still green this can signal a nitrogen deficiency.
Here is an article that will tell you how to correct the nitrogen deficiency in your soil:

I planted a wisteria plant last summer and it took very well. It probably grew at least 8 feet. The vines went woody in the fall, then it went dormant. This spring none of the existing vines came back in, but I have new growth coming in a the base of the plant. Aren't the existing woody vines supposed to come back in?
You should be seeing growth from the vines.
It is possible that the vines were damaged in the severe cold winter that nearly the entire United States suffered.
New branching and buds are formed on old wood, and even a late spring cold kill the buds.
I would continue to care for the plant and perhaps the old vine can just serve as a support.
Here is a few links with more growing and pruning information.

Thinking this issue is fungus. Shall I try to cut off segment of trunk and use fungicide? If so, which one works best? Thank you!
It is difficult to prescribe a treatment given that I do not know more about the issue your wisteria is experiencing. Can you describe the overall condition of your wisteria - can you tell me more about this fungus or provide a photo? Do your blooms and leaves look healthy? Even if a fungicide was necessary, it would not require cutting the trunk.
