I too have a 86 IROC. and I have yet to find a new washer pump that works. but you could have a plugged sprayer situation. or the hoses could be plugged.or you could have a bad pump
Re: Windshield washer pump makes noise does not pump
The pumps have a rubber impeller that turns to crap when they set dry for a while. Also, do you have the check valve on it? Does it work right?

Is there washer fluid in the tank? If it's empty that could be the issue... :-p

Re: Windshield washer pump makes noise does not pump
If you've ever used tap water in washer system that could cause plugging due to the minerals in tap water.
Check the rubber hoses for rot/cracks. Check the hoses for holes as well. Especially if you have a rodent problem. For some reason they seem to zero in on rubber washer hoses.

Have tried running the pump without any of the hose connected to it? That way you can determine if the pump is the problem or if the problem is somewhere in the hoses.

The check valve will cause that.
