Re: thoughts on windshield wiper sprayer not working on front glass.

There are two pumps on the windshield washer reservoir, one for the front and one for the rear.

Since you can hear the pump working it isn't a pump issue which only leaves a few things to check. The sprayers themselves may be clogged with deposits, the lines might be clogged, or the y-splitter/check valve under the hood liner may be clogged or put in the wrong direction. It only flows one way so if it was removed and reinstalled wrong the sprayers will not get any water to them.
