2000 pile of shat xj. 4.0 auto 2wd

I know all these are on the same circuit so one thing is causing it all. There is power on the fuse for this circuit and the fuse is good. My question is would one thing being bad short out the circuit? Like if the evap sol was bad would it make the whole circuit dead? Or maybe the fan relay? I have tested all the relays except the fan one and checked everyone of the fuses one by one.

I found one guy that was having the same problem but he never posted a resolution.

Anybody else had this problem?

 

Forgot the trans shift module is on this circuit also.

Does anybody know where the power goes first when it leaves the fuse box?

 

Does anybody have the wiring diagrams for a 2000 cherokee sport?
