Default Fuel pump?

So i picked up a 91 5 speed 4x4 with just ove 280.000. i put ddp 100hp injectors in it and the next day it started to run rough. It felt like it was running out of fuel (i know what thats like cuz the fuel gauge doesnt work.. for now) It stopped running and wouldnt star again. its got well over 3/4 tank but its not getting fuel to the injectors when i open them and crank the engine to bleed the lines. would it be my lift pump or the sending unit in the tank? and how do i figure out witch one it is?
