i just got done w/ refinishing my squier and i put the bridge back in and sodered everything and put the pickguard on. but when i put the high e string on it just makes a sort of buzzing sound or something and the pitch doesnt change no matter where i fret it. is this a intonation problem? and if it is how would i fix it. or is it something else?

It sounds like it's always touching one of the frets somewhere. If you could raise the action on it, I bet it would help.
