Default fans dont work

i got a 94z and the fans dont work. well the person that i got it from had it all rigged with wires, and im trying to fix it, basically what im asking is


at what temp are they suppose to come on>?
and when u disconnect the sensor on the the waterpump, and "jump" the yellow and black wire(key on) (engine off), the pcm should ground the relays to turn on both fans., right? thats what i gather from looking at the wiring diagram.

well i did that an im not getting a ground at the control side of the relay. so next question-- how often do the PCM's take a poop.?

and im still on the factory exhaust manifolds, -- with no cat back system, (it was killed by the Vseries Tech.) during install.
can i still drive and keep breaking it in or just park and wait for headers?.
