Leave her be for a week. Don't look at her, don't handle her, only mess with her if you need to change water because its soiled or some other pressing issue. Other than that, just leave her be for an entire week.
After a week, get a can of tuna. Drain out the broth or "tuna juice" as I call it into a bowl or small cup or some other container. Thaw a pinkie so its nice and warm and then dip the head of the pinky into the tuna juice. Put the pinkie in a deli cup and the snake in there with the tuna juice laced pinky and put her in a dark closet or some other place where she won't be disturbed. Leave her there overnight. Even if you're tempted, don't check on her until the next morning.
I've had great success getting non-feeders to eat doing this method. Some people have tried this using chicken broth or stock with some success too. I've had best success using the tuna juice.
