Of course, trying a clean nozzle would be the first thing to try. BTW, when

I don't know why it works, but sometimes you can get the thing working by
taking off the nozzle and then putting it back. You'll get a little spurt,
and then nothing. If you repeat this a few times, often the thing will
start to work.

Yup. This one is PLUGGED. Nothing is going to get it spraying again, not a new
nozzle, nothing. And I just need a little more of the paint ..

I'll try the churchkey, sounds reasonable to me.
