1992 Jaguar XJ6 not getting fuel to engine

Good morning. This is my first post as I just registered bout 2 minutes ago. I purchased a 1992 XJ6 Sovereign with 95K original miles on Monday from an elderly gentleman who took real good care of it both cosmetically and mechanically.

Here's the problem; The car was running fine with no indicatin that there wee any issues. He parked it one day and when he went out the next day it wouldn't start.

He was told it was the fuel pump. So he had a mobile mechanic install a brand new fuel pump that he purchased from a dealer. Still the car wouldn't start.

Well after it has been sitting for many months he decided just to sell it and I bought it and had it towed to my house.

I can hear the fuel pump kick on and run when I turn the ignition. But if you disconnect the fuel hose in the engine bay from the fuel rail it is bone dry and no fuel is getting from the tank through the fuel lines to the engine.

Here's what I've done so far;

1. Replaced every fuse in the car
2. Made sure the inertia switch was not tripped. This is the switch on the driver side kick panel close to the firewall in the passenger
compartment.
3. Added gas to the gas tank
4. Installed new battery

I've read it could be the ignition switch, distributor, solenoid, but all of these appear to be working properly.

What I haven't done is disconnect the fuel line where it comes out of the tank or fuel pump to see if it's actually pushing fuel. I think I need to do this and then depending on results move to the next connection (fuel filter) and see if I have fuel going in and coming out of the filter and then depending on results keeping moving forward until I find the problem.

My question is; Am I going about this the right way or is there something I've said that makes one of my fellow enthusiast go; "Oh that's a classic symptom of XXXXX problem"

Are there any other switches that may have tripped on gone bad that my symptoms indicate I should check or replace?

Thanks in advance for your help!
