3.8 no fuel problem ???????

I have a 92 olds silhouette 3.8 it was not starting well when cold so I replaced the fuel pressure regulator and it did not help, so i drove it for about 4 months it recently started running rough on idle when warmed up and would die while driving on occasion. It finally refuses to start. i pulled th fuel line and no gas came out when i cranked it also could not hear any fuel pup noise when i turned the key so i relaced the fuel pump and still nothing(except maybe one click when iturn the key but no gas out the line. I added gas and gauge works, fuses in glove box are good. Is there a relay other fuse or other problem I can check if so there location and how do i test it?? Thank you

It does not pump gas out the line (at filter) when i turn the key, I only hear one click from the pump when i turn the key and it should run more I believe. I think i located the fuel pump relay under the drivers side dash and it feels like its clicking when i turn the key ........what else could it be .. help ???????
