[No start no crank se]

Hey guys,

I got a 02 se and just bought it so I don’t know much about it! First Nissan I’ve owned and trying to learn the vehicle hoping you guys might have some ideas! Most of the time she fires up right away, but sometimes I’ll turn the key and nothing so keep turning off and on and eventually she starts some times half hour sometimes 5 min. 
 Any thoughts on where to start diagnoses? 
anyone have this problem?
