Your bird is seriously ill and must be seen by an Avian Vet in your driving area so he can be diagnosed and treated. This could be an infection or result from some type of toxic substance.
You must get him in to see an Avian vet as soon as you can or you risk losing him. If he is not able to digest his food, which he is not, he will die from dehydration before he dies from starvation. Dehydration is very dangerous, and you need to take him as an emergency as soon as you possibly can.
Let us know what the Avian Vet has to say as your information can help someone else with a similar problem.

I don't know what might be wrong. The only way you can find out what is causing this is to take your bird to an avian vet. A vet will be able to examine your bird, get the history and run tests.
If you don't have an avian vet, you can look for one on our Find an Avian Vet page. We have some vets that people have suggested and also links to other avian vet websites where you can search for one.
If your bird has not gotten the polyomavirus vaccine, you should have this done when you take your bird in.
