Have you ruled out a UTI? I suggest ruling that out first before thinking it's behavioral. Once that's ruled out, you will have to start over. How large is her crate? It should only be large enough for her to stand, turn around and lay down. When you take her outside to potty and she doesn't, she goes back in the crate. When she eliminates outside, throw a party and treat.

Are you correcting your male for marking? Is he neutered?

Also, she needs to eat 3 times per day. Feeding half of her daily rations in one sitting is too much for her little belly. She should eat 3 times per day until about 5-6 months.
