Shut off and will not start

My Viggen just stopped running and I can't get it started. It will run on starter fluid, but not on the normal fuel delivery system. I replaced the fuel pump and filter. When I turn the key, I think I can hear the pump running. The pump fuse is okay, and I changed the fuel relay under the dash. The part was in another Viggen that was running. The battery is fully charged. Could it be an airlock in my high-pressure fuel line? I do not have the plastic tool to release the fuel line up by the fuel rail.
I appreciate your help as I am stranded without a car! Peter

My Viggen runs on ether but not on the fuel delivery system.
