2 broken front pumps. what is a wave plate
SOURCE: Changing a water pump on a 2005 GMC Pick-up
Open the hood of your truck. Look inside the engine bay. See the fan assembly and the pulley that the belt rides on. The water pump is behind the pulley. Changing water pumps can be somewhat of a task. Professional help will be needed for someone that can't find the waterpump.
The water pump is on the passenger side front of the engine; I had to drain the coolant, I kept the belt in place, then I removed the 3 bolts from the pulley to give me access to the bolts on the top (it will require a set of metric tools for it). Then I removed the passenger side front tire and the splash cover from under the car just above the tire, removed all bolts that holds the pump on the lower part of it, then removed the belt, scraped and clean very well the old gasket. The new water pump came with a new gasket, so I just got a gasket maker and applied to the gasket, so I did not have to do it again. Work backwords to reinstall everything, good time to replace the coolant and if you have not done yet, replace the thermostat valve along with any hose that may be cracked, rigid or enlarged (check the hoses to the heater core also). Please check your belts and hoses so you will not have to redo the process again.

unfortunately you will need to drop the gas tank ....you will need a jack and jack stands for safety reasons and some tools sockets - {deep-well} and screwdrivers and patience and hopefully a warm area and pliers ........if you decide to do this first i can give you more detailed assistance on what to expect as well as difficulty level etc.....a few hours i assure you a bit of difficulty depending upon your mechanical skill and health i know i had to have mine sent out as i could only get it 3/4 the way out and i have been an auto/body mechanic and suspension paint metal etc for over 34 years but my health issues restrict me from even the simplest of tasks at times i hope this helps you in making a decision and ...................ensure in fact it truly is the fuel pump 1st have you determined this yet ? a pressure test can be made for free from most parts stores and a few major repair franchises

First, copy this diagram down so you will have a guide to putting your serpentine belt back on when you need to...
Follow this link to a "how to" video on replacing your vehicle's water pump. It will take awhile to watch the video(s), but will be well worth it.
