I had the same problem with my Audi. I had no voltage going to the fuel pump. I replaced the fuel pump, Crank sensor, fuel pump relay, cam sensor and checked the fuses. The fuel pump still didn't have power.
So the last thing I replaced was the ECM ( engine control module) the vehicles computer.
The car started by replacing the ECM.

So my best guess is you have a defective ECM.

Thank you. That is what I was thinking after looking at the wiring diagrams.
