1994 Chevy Cavalier wont start sometimes

I would check the starter and battery

If it doesn't crank you need to check and or replace the starter
if the starter getting to hot will not crank until it cool down
check charging system
if the alternator not keeping the battery fully charged then it will not have enough to spine the engine when hot

if crank but no starter check for spark and fuel pressure

If it doesn't turn
I would recheck the alternator and charging system
recheck the starter
recheck the battery
when it does it try to get a jump
if start with a jump check the battery and charging system
