2000 Saturn whinning sound

I tried to start my 2000 Saturn this morning and after I turned the key on it acted like it was going to start then all I could hear was a whinning sound. I have power. I have replaced the starter and still have the whinning sound. Help.

just wondering, is the whining sound the starter spinning the engine? You may have lost compression. If the timing belt is bad or the lifter has bled down, the engine will spin but it will sound different because there is no compression when the piston comes up. have someone turn the key for you and you watch the pulleys in the front of the engine to see if they are spinning.
