crown vic wont start at times

i have a 96 crown vic that starts and runs perfectly most of the time, but other random times i turn my key and nothing happens, my radio and lights function but the car doesnt even try to start so i give it a little while try to start it again and it fires up perfectly.. i have no clue what the problem could be. any help would be great.....

its called a cold start or dead start something like that. but check your starter for corrosion
