Make sure you didn't inadvertently turn off the display...
Use the pushbutton on the bottom of the wiper stalk and
see if you can turn it back on.

Probably the pump...  The definitive way to test is to check if
there is voltage at the pump terminals when your headlights are
on and when you activate the winshield washer.  But that pump
is not readily accessible without taking a bunch of stuff apart.
