Point your water line into a bucket and turn the water on at the wall. If you get a good flow, we'll go back to the faucet. No kinks in the supply lines, right? The reason I ask is this was reminiscent of a recent problem where my friend could get hot water to the faucet, and it would slowly go down to a trickle. The problem was that the supply hose had a bit of a kink in it, and got choked off when the line got hot.
OK, good flow into the bucket. Sometimes the supply lines can delaminate, and choke the water off as well. Since you have a sprayer faucet combo, make sure that the flex hose that dispenses the water, and has the weight on it to retract the nozzle back up doesn't have a kink either. Remove the spray nozzle, and try the faucet, holding onto the hose. It's possible that the spray selector could have a problem, so check the spray head and diffuser. With the water on, push the sprayer button, and see if the problem might be there. Remove the aerator on the end of the sprayer, and check the screens for pluggage. My guess is that the issue is in the spray head.

Sounds like you might have the rubber cup seals installed upside down? The spring goes int he body first, then the cup seal goes over and on top of the spring.
Question edited for correct spelling of maker 'Noen' to 'Moen'.
'Fix' as in it is leaking? Or tighten it down because it is wobbly, or something completely different?
Well, we can have a one on one seminar by the internet. I've been a pumpman for 20 years. I can share with you my experience (household pumps, suibmersible pumps, turbine pumps, gear pumps, piston pumps, dewatering pumps, mud pumps, trash pumps, mining pumps, solids handling pump, etc....) Just take your pick. Just send in your e-mail for assistance. God bless.
It is leaking due to a defective mechanical seal. It needs to be replaced. To replace it, is to take the pumpcase off by taking off the bolts that hold it. Then, take the impeller off to take the mechanical seal behind it. Put the replacement in, and reassemble the pump. Just get in touch with us by e-mail to get more assistance.
Move the lever or turn the knob. Check the stop tap under the sink. Make sure the faucet control knob or lever is tight, There is normally a removable cover that hides the screw..
Question edited for clarity, full 'make model (what it is)'.
This a Menards special. To remove handles, look for a small hole hidden from the front. They take a small Allen Key.
