If not, here's something that worked for me on my grayband when I first got him (he'd eaten once for me, then stopped like yours has). After warming up the pinkie, I used tweezers to show the pinky to the snake, then have it slowly back away from the snake. He hesistantly followed, then got more aggressive and false-stuck it. I had it back up further, then he actually took it and ate it. Did this little "mouse dance" with him for quite awhile, but it worked. As long as the snake is following the mouse, he's interested and getting up his nerve to strike.
I've also just held the pinkie still in front of a snake, then slowly turned the tweezers half a turn clockwise then counter clockwise (still slowly) and gotten another snake to eat that way.
I think it's movement, but slow movement that doesn't frighten the snake and triggers feeding response in timid feeders.
Don't know if that'll work on yours, but thought I'd pass it on in case she's still not eating.
