Myself manually for 2 days but it won't turn on,
Is my pump burn??
Ihad it since the pool got build,(6-7 years) ihave a Saltpol

Most likely, it is burned.

If you know your way around a multi-meter, you can test it.

If not, you have two options:
1) Call an electrician, and have HIM test it.
2) Get a new pump and have an electrician install it.
