There are two reasons that nothing would come out of the bleeder. Either the bleeder is corroded inside and all plugged up so nothing can get through or the level of coolant is so low that the pump is airbound and is not circulating coolant. Take the bleeder screw out and stick a piece of wire in and poke it around to make sure the hole isn't plugged up with crud. With the motor off and enough coolant in the system it should run out the bleeder now. Now look inside the bleeder screw and make sure it isn't blocked up. Now you can bleed the system. There should be no need to replace the water pump, at least not for this. If it is the origional pump you might want to consider replacing it and all of the associated hoses and seals and belts, it is over 20 years old you know.
