1995 pontaic grand prix 3.1 v-6

I just had motor replaced, the cooling fans will not come on. There is power to the fans, but they still won't work. Also now fuel pump keeps running. Any help would be greatly appreciated. thanks

Is the car overheating? Fan's will not come on unless motor reaches a certain temperature.

If it's cool enough out, even with the A/C on, the fans will not turn on unless it get's hot enough.

As for the fuel pump, I would replace the relay for it. It may still be stuck in the closed position.

If relay is ok, I would say your ECM (engine control module) is fried.

yes, car is overheating. It got so hot, the head gasket blew, and turned my oil into a milky gel. I thought by replacing motor,it would slove problem, but it is still there.

I would look at your ECM like I stated earlier.

Your fan and fuel pump, along with alot of other things are controlled by the module.
