You could supply the pump with a known good 10 psi of diesel fuel and stand alone the pump and then bleed the lines. It would rule out ecm and low pressure fuel system.

Crack the lines and try a few more times. When my fuel gauge quit on me and I ran my truck out of fuel it took several lift pump cycles before I got fuel to the injectors. Also you might take the overflow valve off and see if it is stuck open.
