I know for a fact that you cannot flood a fuel injected engine! Unless you converted your taurus to a carburetor setup, somehow?? Unless, by flooding, you mean your wife parked it on an incline, the tranny failed, and it rolled into your pool...?
As far as the steering goes, if there is water in the system somewhere, perhaps in the rack itself, a proper flush and fill will solve the problem. The dealer that performed the work should have the part numbers from the parts they installed on the invoice (or somewhere). So, if the engine shop did replace your pump and lied to you, you can easily get your money back if you can confirm that the engine shop did replace the parts. I highly doubt a dealer would install bad parts as their reputation for not only service, but sales will be at stake. The power steering whine may not be the pump. I'm having a similar problem with my Durango at the moment. The steering whines, and there is a very slow leak somewhere around the rack, as my pump and engine block are all nice and dry. Gotta love maintenance!
