1997 Toyota Camry 2.2L, 130k miles
I located the leak by pouring water into the reservoir. There were a couple of cracks in the u-shaped hose that's clamped to the pump outflow, so I replaced it with a small length of hose, applied new clamps, and refilled the tank. When I test it though, the pump turns on, but no fluid comes out. If I remove the replacement hose again, to check, fluid pours out of the pump outflow nozzle, so no clog.
Before replacing the hose, I tested the system and it worked great, now I'm getting nothing. Do I need to prime the pump somehow? All advice online says it should just work. Is it possible that I damaged the pump somehow, or is there something else obvious going on here that I'm missing?
Any pointers would be helpful!

No, there is no priming involved. Either there is something wrong with the repair you made or it has a restriction further down the line.

Huh, well that problem solved itself. So, I thought I'd run the washer pump for 30-45 seconds after switching the hose, to test it, and it didn't appear to be pumping. I hopped in the car this morning though, gave it a try, and lo and behold it's working great. I guess it takes awhile for the pump to refill the lines. Can't imagine what else it might have been.

Bart - such basic things yet needed and pest to get at many. As HT said no priming needed and I seriously think almost all can run dry without harm. High bet is debris somewhere or stuck in air couldn't get liquid to it.
Dang things are able to run frozen (nothing moves,) empty too. I'm near sure the "INLET" side can't suck fluid up rather placed low.
Eeek - for such simple but so needed a thing the outlets are tiny some like a BB you turn with a pin, some one with two of those. Those clog easily. Answer is be real careful fluid is clean, cap on all the time.
Check if this persists or does it again near certain you can leave failed pumps and in-line a generic one using wires to OE ones if room to do that. Have two on hand new just for that either quick temp fixes or leave it if fine,

Yes, the intake for the pump is submerged in the solvent so definitely no priming involved. It takes a total of 1-2 seconds for the fluid to reach the nozzles.
As Tom suggested, the inlet may have been restricted or the pump was bound up and not building any pressure.
