CUMMINS ISM ENGINE PROBLEMS.....WILL IT START? OR IS IT JUNK? PT1

THIS IS A TRUCK I BOUGHT AWHILE AGO....I WAS TOLD THAT THE TURBO WENT BACK. THE DEALER REPLACED IT AND THEN TOLD THE OWNER THE ENGINE WAS BAD......WE REMOVED THE WATER TANK, PTO, PUMP, SPRAYERS, VALVES AND CONTROLS. THEY WERE SOLD OF TO RECOUP SOME OF MY INVESTMENT IN THIS TRUCK. WE ARE GOING TO START AT BEGINNING WITH THE BASICS AND FUMBLE OUR WAY THROUGH THIS TO FIND OUT IF IT IS WORTH FIXING OR PARTING.
