2004 Other Isuzu Models fuel problem

Engine Mechanical problem
2004 Other Isuzu Models 4 cyl 300 hr miles

I have a 2004 1.7 direct injection diesel engine in my boat. The fuel level signal lied to me and I ran out of fuel at sea. Re-fueled, verified sender was shot. I have bled the injector system up to the nut holding the fuel line to the injector. Still won't start. The man/auto fuel shut off is in the manual position.
