You have a decision to make.
You can take the car to the dealer, they will install a new pump and you will pay somewhere between $900 and $1100 depending on their price structure. And you will have a one year warranty on the labor and the part.
Or you can go to various sources and buy a pump for between $290 and $310 - eBay price and Amazon price - and do the install yourself.
I watched Dr Dave (DDM Works) pull a bad pump out of one car, pull a good pump out of a car on a trailer, and do two installs along the side of the road in under an hour. On the way to the Nationals in Washington State two years ago.
Pull the wiper arms, pull the cowl, crack the high pressure fitting on the pump to relieve pressure, remove the bad pump, install the new pump, replace cowl and wipers. Drive the car.
If you do it your self, they also recommend that you replace the gaskets and mounting bolts. If you buy a replacement new pump, mine came with the mounting bolts and I spare the gaskets.
We discovered that GM had ONE HPFP in inventory in Washington, Oregon, and Idaho. One. And it was over $600 just for the part.
I now carry three spare HPFPs in the truck when we travel over the road with the club.
