Default 1970 Deville Cranks but won't start

My car suddenly stopped running today while driving. When I turn the key the car cranks strong and i hear a repeating putting sound when cranking like the car is trying to start. I poured about a 1/4 cup of gas in the carb and the car ran for about 5 seconds but very roughly. Also, from time to time the engine would lose power and backfire and I would have to either turn off and restart the car or rev the engine really high for a few seconds for this to go away. I'm wondering is this a timing problem, or do I need a new fuel pump?
