84 Deville won't start

Hello All,
I'm new here and have searched already so just be patient with me. With that being said, this is my first Caddy. It's a 84 Deville w/4.1 and it wont start. Long story short 2nd fuel pump later and i am now hearing it prime when key in ignition. Changed fuel filter, tightened it all up, let it prime several times to re-pressurize system and fuel line from filter, to solid line has hole and leaks. Change line, try to start car and will not start. The car turns over, and will start every time with starting fluid but not seeing fuel squirt from the 2 injectors. What else can i look at as the problem. Thanks
