First of all, move her crate to a new location, preferably one in the same room you're in at the time. And give it a new name. Only call it her "Happy House", not a crate, which probably has bad connotations to both of you now.
I'd only feed her in the crate, of course with the door wide open. So her every meal fro now on takes place in her Happy House. Keep all her favorite toys in there. Using your cartoon, happy voice, praise her lavishly with a smile in your tone every time she enters her "Happy House" and lightly clap your hands, celebrate with big, happy smiles and toss in her very favorite most treats from time to time during the day and evening. Make it seem like she's won the lottery every time she steps a paw inside that "Happy House".
Lure her into her Happy House with toys or her favorite treats tossed into the crate. When she goes in, celebration using your happiest cartoon high, squeaky voice to praise her and whoop it up with her.
Place a worn t-shirt or two of yours in there to help her feel connected to you so she can snuggled down to your scent. She can dig them into a nest of her very own making as Yorkies are want to do. All three of my Yorkies loved making their own bed using their paws and dragging the loose blanket or t-shirt into whatever shape they wanted for the nap to come. Encourage her in every game you play with her to make a "Touchdown!" by running into and out of the Happy House, follow a toy you've tossed i into it, retrieve a ball from it. From now on, only smile when you speak of her Happy House to her and always, always, always feed her in it. She will slowly come to connect only good things like dinner time, your strong scent, treats, toys, games, fun with her Happy House. Your change in attitude in suddenly being totally in love with her Happy House will strongly affect her so your infectious "love" for and display of affection toward the Happy House will grow on her.
I used to pat a rescue's crate and use my softest, highest, sweetest voice when I did as I walked past it, saying "Gooooooooooooooooooood Happy House. Gooooood House! Mommy loves you, Happy House". Big smile on my face, high, squeaky voice, good, fun and game, winning associations and his meals in the crate all came to strongly influence that scared little dog that his crate was the best place on earth.
Once I read the clicker article about "You Won The Prize" I knew I'd done right by my little rescue pup. Well, he showed me I had by learning to love his previously hated crate but read this and see how changing YOUR attitude, your way of positively handling the dog and the crate can positively affect your dog:

These happy, positive associations with going into the crate, our happy, happy attitude in putting them in it will eventually change their negative associations to positive ones. Don't forget to occasionally toss in her highest valued treat(warm, freshly boiled unseasoned chicken meat or bits of turkey hot dog!) to make a "Touchdown!" and reinforce her running into her Happy House for a great snack and your celebrating it with her. You'll make a great team! Eventually, you can close the door and leave her in there for 1 minute before you return with high-toned praises and another treat for staying. Gradually increase her times in the Happy House so help train her to stay in her safe house whenever situations requre it. Always make it the highlight of her day to go into her Happy House by YOUR great attitude. Never wane in your enthusing for it! What's to lose?!?!
