Jerry,
A couple of dumb questions for you, but
1. Is your fresh water tank full?
2. Is your auto-fill switch on?
If the answer to question 1 is no, you must have water in your fresh water tank. Without water in the tank, the pump will give no assist to incoming water.
If the answer to question 2 is yes, you must have that switch off. If it is on, it just keeps pumping water through the pump back into the tank and it seems like there is no water pressure.
I know you probably have made sure these to conditions are as needed, but all your recent posts indicate either of the above conditions.
