Doubt the crank sensor is a problem. Fuel pump priming does not require a crank sensor signal input. You have spark, so this kind of means the crank sensor should be working, however, some engines can fail over to the intake cam sensor input to use as a trigger for spark.

You have a fuel problem/electrical if no fuel pressure is at the rail.

Either the fuel pump dead, the fuel pump relay is bad or there is some other electrical related problem.

I would bypass the fuel pump relay and see if you can power up the pump with a separate power source.
