Please help! 2000 Nissan maxima wont start.

[player199]

I drove my car to work without any problems, 4 hours later my car wont start. It's not turning over. I've checked all my fuses and they're working fine. I installed two new crank sensors, and im still not starting. I've also noticed that there is no check engine light whenever i try to start. My starter and alternator are fine as well. Any thoughts?
