Check the bellows and any other source of vacuum leaks.
If you've swapped around different distributors and air flow assemblies, you need to adjust the base line mixture by turning the mixture adjustment screw. It's possible the mixture is just too lean with the new combination of parts.
1979? It should have a Lambda controller. Any time the fuel pump is running you should hear a buzzing sound from the pulse modulation valve near the left headlight area. No buzzing, not working, won't run.
