Dead cylinder; I think it is the injector

This car has been in storage for a year. I started it last week and it was running on three cylinders. Traced it to #3.

(1) There is spark at the plug, and I swapped in a different plug with no change.

(2) I get about .6v at the injector plug. Swapped #2 and #3 lead and #3 cylinder is still dead.

(3) Compression on #3 is 150psi

It would appear that the injector is not opening at all as removing the plug wire or the injector lead while at idle does not change the obvious miss.

Anything else to try before pulling the injectors?

Thanks, Randy
