There could be a lot of causes for this. If the thermostat is stuck open, the computer will read that as the engine running cool and not turn the fans on. Also make sure to check the coolant temp sender units are working properly. More direct reasons could be corrosion or damage the the wiring of the fans themselves. Try wiring the fans to a direct source of voltage and see if they work. These key steps should put you in the right direction.

Radiator fans

It may be your relay! A way of checking is unplug the fan and put a test light on the plug itself with a/c running and if it doesnt have any power going to the fan with a/c on then your a/c fan relay is probably bad!

Spark plug gap size for 1991 formula firebird

See if you still have the Vehicle Emission Control Information label (the VECI label) under the hood on some radiator support member, probably. The spark plug gap is listed on it.

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 .

Thermostat is not opening, or is installed backwards is why the hose stays cold. Make sure the nugget is facing the engine block. If this is correct, make sure the belt is installed correctly and is rotating the water pump in the right direction. The fans are turned on by the PCM. You will need to get a diagnostic chart and follow it to find out what is going wrong.

1989 formula firebird

On that particular model, you'll have to unbolt the rear end enough to lower it to gain access to dropping the tank. Use a jack and lower it about 6 - 8 inches. Once you're done that, you'll be able to remove the gas tank and access the fuel pump to replace it.
