Welcome to AF, not much info here, is the engine noisey was the pressure checked with a seperate gage, how many miles??

the truck only has 77k miles on it and the top end is clatter really hard so its obviously not getting any preasure and our gauge is reading less then 10lbs of preasure

The oil pump may not be the issue, worn cam bearings, bad rod bearing, worn pump drive.
