As stated, it should self-prime. Until you replace the pump consider creating a suction to draw water into the pump. For example, close all faucets except kitchen sink. Use a baggie and a rubber band to cover the faucet spigot. Open only the faucet's cold water and with the pump ON suck hard on the sprayer with handle depressed. And consider having someone standing behind you should you pass out. Alternatively, next day shipping.
