Newer engine installed.. Fan wont turn on, temp guage doesnt move

[xunearthhxcx]

I did a little searching, but im still not exactly sure ill get the correct answer without explaining things.. Anyways, you might know me from this thread (http://www.318ti.org/forum/showthread.php?t=27480) I bought a clubsport, and within 13 miles of purchasing, the head gasket blew...

well, I got a good used motor. My mechanic put it in, and the car honestly starts runs and moves as it should.. One minor thing is holding us back from officially letting it out of the garage..

The fan WILL NOT turn on. also, the temp guage on the cluster, doesnt move a smidgon! This may have been the reason my previous motor blew up. not sure!..

anyways, we tested the fan using the paperclip trick(see, I did search a bit!) and both low and high worked just fine. Checked all fuses and thoselooked good as well. Turned on the AC, and the fan still wont turn on.. SOMETHING isnt right here. everything else works just fine on the car. Im thinking its possibly one of the blue or black sensors plugged into the head of the engine.. the blue is the temp sensor, and the black(under the damn intake) is the "remote thermometer sending unit" .. am I correct so far?

Tested the radiator temp sensor? on the passenger side of the radiator. and the actual plug that goes into the radiator has no voltage, but the sensor to put into the radiator plug has good voltage. I dont know if it makes a difference or not.. But we are stuck right now.

Anyways, id like your guys input. as this seems like SOMETHING has these all related somehow..there has to be something that isnt sending a signal, or something plugged into the wrong sensor , something! ugh I just want to be able to drive my damn car !

thanks for any help guys.
