My 92 Honda civic car won't start at all no lights or nothing?

Test the battery first, then the alternator.

Check all fuses and fusible links first, specially there are two fusible links 39 (50A) and 41 (80A) in the under hood fuse/relay box. Do you have power to all of them. If not, then recheck the battery state of charge, including all cables and its terminal and go from there. Was there anything done to the car before the "nothing" happened? Jump starting? Any recent work has been done to the car?
