Change the thermostat,and bleed all the air from the coolant system,the sensor has to have coolant to contact with,not steam,or hot air pockets,it will not sense this,so you see it has to have coolant on it at all times to make it sense the actual temp.

I have a 1989 ponitac firebird. The car runs great for 15 minutes then cuts out. The coolant fans do not come on. The radiator, and all the relays have been replaced along with the ECM. I have replaced...

Replacing part's is not the way to diagnose ! Hooking up a OBD 1 scan tool an viewing engine sensor data parameters is . Did you do this ? , What engine ? 2.8 , 5.0 or 5.7 l
Coolant fan control switch at 238 degrees closes an supply's a ground for the cooling fan relay ,their by energizing the relay an closing the contacts sending B+ voltage to the cooling fan Or the PCM does ,depends on which engine . There is a fusible link that supply's B+ voltage for the fan it's self . A fuse for the control side of the relay . Did you use a DMM - digital multi-meter an test B+ power circuit's & ground circuit's . Maybe your best bet would be to take it to a qualified repair shop .

The fan wont turn on when car gets hot

Overheating or just hot? Your temp sender sends signal to the computer that sends a signal to the fan relay that turns the fan on. You can hotwire the fan motor to the battery to see if it runs. if not that's the problem. Otherwise follow through by checking sensor and relay.

My protege 94 leaks black smoke from engine after traveling 1 or 2 mile. When I see cooling fan after starting engine, it does not rotate. what might be the possible cause.

The fan does not rotate all the time.
Temp. senor provide reading to the computer ECU and it will trigger a fan relay to turn on the fan.
The three leakable items are
oil pressure sender/oil sending unit
coolant temperture sensor
valve cover gasket.
Clean out the motor with cleanser when it's cold.
Start it up and look for the location of the leak(s),
Please post more info on the comment window.
I will follow up on it.

Fans wont come on

Does the temperature gauge on your dash work okay?

The coolant temperature sensor provides a signal to the PCM to tell it when to turn the fans on and if its a three wire coolant sensor it also feeds the signal to the gauge on your dash and if the gauge on your dash is not working, it could be a clear sign that the sensor is dead.

However, to start with the simple things, first check the fuses that power the fans, it will be a large fuse probably in the under the hood fuse box and maybe in the 30A range. Check the fan relays as well.
