95 XJ6 cranking but is not getting fuel

Recently my died, after towing it home I assumed it was the fuel pump since I didn’t hear it running, I replace the pump and filter, checked all fuses and switched the pumps relay with another. Pulled the 1st plug and I’m getting spark, pulled off fuel lines to rail and cranked it over, and didn’t see any fuel come out. I hear the the pump working each time I try start for about 2-3 seconds. Does anybody have an idea where to start?

When was the last time you changed the fuel filter? Also look at the fuel lines and fuel pick up in the tank.

Is the fuel getting to the fuel pressure regulator?

Changed filter when I replaced the fuel pump

I disconnected the line to the reg. and cranked the engine…nothing.
