1st thought; fuel pump failure (shorted) or you maybe looking at a computer failure.
You can or should be able to hear the fuel pump whirl momentarily when you trun the key on till the fuel pressure is up.
Uncommonly the fuel pump relay can fail but unlikely! It is east to isolate but any problems with fuel pump you are likely going to need a complete fuel pickup assembly with fuel pump because it probably severly rusted.
You could probably do the easiest test if you pull the fuel pump relay and bypass the relay at the four pin plug socket lower left dash... relay should be attached to computer case bracket.
