Default Fuel system problem

my 97 diesel acts like it ran out of fuel, which it may have because the fuel gauge does not work. I loosened the injector connections, turn the starter for 30 seconds and repeated this several times without getting fuel to all injectors. It won't start. I cannot hear the lift pump but this model may have the mechanical lift fump. I tried priming the pump several times for nearly an hour. Still won't start.

Any suggestions
