It has to be the water heater, right?

9 yr old home with a gas fired water heater. At the sinks throughout the home, the water pressure was fine on the cold water side, but nothing from the hot water side. The water heater was on(flame), and did have water in it. The branch line from the water heater was warm to the touch but no pressure when I tried to engage the tpr valve. What might cause this?

Simple gravity flow, typical Rheem gas water heater. Correct no escaping air or water when the TPR was opened.

Then it seems to me that the cold water inlet valve was defective or otherwise not open. If it was open, you'd feel the whooosh of the escaping air when you opened the TPR.
