windshield washer problem

[gmc1971harwich]

i turned the windshield washer on the other day and i heard the relay click once instead of numerous times while it was pushed down as usual but nothing was coming out. i assumed it was the pump so i replaced it with a OE pump, now same thing happens. any ideas? i didnt replace the star shaped plastic piece in the kit though and im wondering if thats y has this happened to anyone else? if i cant figure it out im going to make a trip to autozone tomorrow for a universal pump. its got me stumped.
