Welcome to Diesel Bombers
Are you getting fuel at the injectors?

It is possible that the injection pump failed from no lift pump pressure. Is the injection pump mechanical or electronic?

The only thing I could suggest is starting as near to the lift pump as possible and check for fuel there and work forward.
What about a relay for the lift pump is it clicking is the lift pump running?

You could also hook up a pressure gauge and see if you have any fuel pressure from the fuel pump.
But it is possible that the fuel pump went out after the lift pump went out.
