This is a pretty vague question.Are you mechanically inclined? Have you had any tests run on the car. Basic test would be check the voltage on the battery,car running and engine off.Will the engine crank? Check your air filter to make sure it is not stopped up. Check to see if you have any spark going to the spark plugs.Check for fuel delivery. Is the check engine light on.What happened prior to the engine not starting?Do you have antitheft system? I would need more information to be of any further help. I hope that is a start. There are two websites that might be useful to you. One is www.nissanhelp.com and the other one is www. pdftown.com. both of these websites have a lot of good information on technical service bulletins,recalls,specifications,technicql manuals,maintenance information. You will have to register on them to be able to login. Hope this helps!
my 2000 nissan altima wont start has new radiator and spark plugs the computer test shows no problems it recently overheated
Specify the year.
overheated and wont start
Put gas in it - idiot
change the blue box maybe.
combustion engines need 3 things to run: fuel,spark,air
Could be vapor lock. The vent on your gas cap may be clogged

What the #%$& does that mean. Who ever made that up is a crazy son of a #$&%@
Maybe your alternator needs replacing.
It seems that there could be a problem with your starter. It happened to me too.
Damaged fuel pump?
