does the belts turn when you try to start it?, if so remove the serpentine belt and see if it still grinds, if so check flex plate to starter, then internal engine bearings. I had a broken flex plate

thanks lestro for the advice
havnt tried it out yet prolly tommorow
but any answer on the focus parts??

Is it the starter that is grinding?
