When you say no start, but you hear a clicking. I'm guessing there is no crank from the starter? I got an 02 Sentra, but I have a crank no start, and the biggest clue I have is there is no "service engine soon" aka check engine light showing up on the dashboard. Many videos point to replacing the computer which I did, and that didn't do anything. Other videos point to the exact relay in your video located behind the globe box. I replaced it and it did nothing. I'm still at no check engine light, crank no start. One video suggested a damaged wire coming from the battery fuse box, it says follow the wires until you find the short.
