Suddenly have no power steering
I recently changed both my power steering pump and power steering control valve, it worked great for the past week or so. Then this morning after warming the car up I was pulling out of the driveway and the steering felt pretty stiff, then I noticed at a stop it was very difficult to turn the wheel. I stopped to check the belt, tight, so I checked the fluid level, right in the middle of full and add. No leaks - so, what are my options? As usual, thanks for looking and any help you can give.

I think you nailed it DUB, I did put in a little more fluid just to bring it up close to the top, started it up - no movement

Recently there was a posting where a new PS pump had a stuck flow control valve. If that valve (which is located inside the pump) sticks you will not have any power assist.
Remove the power steering hose assembly, now you will be able to unscrew the pump discharge fitting. Behind the fitting will be a slider valve and then a spring. You should be able to take a long probe and push on the valve. It should easily slide back and forth in the pump housing valve bore against the spring. If it sticks you have found the source of your problem.

jim, just so i'm clear on what i should do, in the picture below (taken from one of your papers - thank you), after taking off the power steering hose from the back i unscrew the #24 in the pic below to test if the valve is sticking or not?
thank you for your help and time! Tony

Thanks Dub, I did pull that out but didn't find any spring. I probed around in there with a phillips screw driver but couldn't get anything to move so I put it all back together, filled with oil and it worked. It fills stiffer so I don't have high hopes that it's going to last but at least I am confident that it is the pump.
