One zone not getting enough pressure to lift heads

I have a rain bird system with 2 zones that are wired together. The system worked fine for the last few years. Now one zone does not seem to get enough water. If I manually open the rain bird ez bleed solenoid I get plenty of pressure and everything works fine. So I figured i had a Solenoid issue and replaced both of them with new ones and still have the same issue. Any ideas what to try next?

There might be a blockage in the narrow passageway under the solenoid. That would account for the symptoms you describe. Clear it out with a stiff wire.

Replace the diaphragm.
