Dog doesn't want to uring outside any more?

You need to start from the beginning like it was a new puppy. When you take your dog outside offer a lot of encouragement. Try to take her to a quiet place to do her business. Crate train her.. Get a crate not much bigger than the dog and keep the dog in the crate when you are sleeping, not home or unable to watch her. Take the dog outside to do her business immediately when you take her out of the crate. Take the dog outside to do her business immediately after eating or playing. When you have the dog out of the crate and are watching her look for signs that she is about to go (sniffing, circling) and take him outside. When she goes outside praise her. If she has an accident in the house and you witness it in a stern firm voice tell her "no potty outside" as you are taking her outside. If she has an accident an you do not witness it unfortunately there is nothing that you can do about it. Do not yell at the dog or hit her and do not rub her nose in her mess. Make sure you are consistent and persistent with the training. Always praise a lot when she goes outside. Good luck.
