The clutch peddle comes all the way up before the clutch grabs do I need new clutch or can I adjust the cable on 93 Honda accord Lx

I'm pretty sure it's a hydraulic clutch, no cable to adjust. This would mean that you probably need a new clutch.

Sorry, you need to install a new clutch set; i.e. clutch, pressure plate, pilot bearing, release (throw-out) bearing, and alignment tool. A Perfection Clutch Set will run around $108 at Advance Auto Parts--less, if you buy online with a discount code. It's all hydraulic, no clutch cable to adjust.
