I have a 2000 jeep Cherokee auto non 4x4

I went ahead and bought the neutral safety switch from quadratec because my jeep just wouldn't start and the code I got from my ecu was that it was the nss (I checked all the other possibilities that another post said to check) . I took it off and put it on with no problem, aligned it "to my knowledge" but now the car cranks but just wont start I think I've read over a dozen post on how to put it on and off but still nothing and Im not getting no codes.

I grew up working on cars but this is my first Jeep so I think i finally hit a wall

Any help will be greatly appreciated
