Firebird starts then stalls

89 Firebird 6cyl. Stepped on gas at red light (now turned green) and it died. Pushed it parking lot and this is the story: Turn the key and it starts and then stalls right out. Try again, it
starts then stalls right out. After 2 or 3 of these it wont even sttempt to start. Wait 5 mintues, try again, same thing again. Have spark, changed coil, cap, rotor and module. Disconnected fuel line and pumped about 10 to 12 oz fo fuel in 15 seconds. The book says it should be 16 oz. IT was hard to measure in a 20 oz container.
Does this sound like a fuel problem or electrical? Thanks Jeff
