Engine Mechanical problem
1978 Pontiac Trans Am V8 Two Wheel Drive Automatic 213000 miles

I replaced my fuel pump 3 month's ago with a high performance Mr.Gasket pump. i went to start it when i was done and it didnt want to kick. We tried started fluid and it would start right up then die 5 second's later even while flooring the gas pedal. Monday i tried looking at it again and see what i can do and my dad noticed that there's no gas going to the carborator. How can i fix this?
