- It seems as though your cold valve is cutting off supply water, but it assumes the top portion of that valve shuts flow from the mixing chamber. That part is not sealing, it is allowing water up the handle cavity. That function is apparently done by the yellow parts with O-rings. Either O-rings are bad, or the part is not seating well enough. Typically all elements of sealing are independent of the handle and are part of the "valve," there being a hot halve and a cold valve.
This is helpful, er, educational. Thanks!

- Weirdly, your faucet design would appear to need the handle assembly to "complete the valve." (Or maybe you inadvertently took the top chunk of the valve along with the handle).

Yes, my wife found the handle in the sink.

Clyde -
Installing a new faucet is pretty easy. The only specialized tool you should need is a basin wrench (a link to one on Amazon is below), which makes it much easier to reach up behind the sink basin and loosen the nut holding the faucet to the counter. You might also need to put a small mirror in the cabinet to help see up there if you can't crawl in (if your cabinet has a center post between 2 doors -- if so, it can be hard to crawl in there)...
We've replaced faucets before (and ones with much trickier access issues than this one). Not worried about that.

Thanks for all the help and suggestions, guys!
