With the noises you discribe and the fact it stops with the clutch depressed it sounds like a major trans problem.Maybe the selector bolt has sheared off which you discribe with not being able to engage gears.Biggest problem with this is that the bolt head,when it breaks, has a havit of falling into the trans and jamming between gears and the case,nasty noises ,sometimes is punched out of the case...cracked gear cases..check for any leakes etc...The BEST fix is to fit the 2002 Focus MTX75 shifter tower assy along with the larger uprated ball ends on the shifter cables Vs the 'pin' type...we do this as part of upgradeds to boxes built at HMS Inc..
