1986 Deville Fuel Pump problem
 

Started car, chattering under hood, car died and will not start. Replaced Fuel pump relay, fuel pump, fuel filter but no fuel getting to engine. Can pour gas in carb and engine will start, but quits after fuel burns off. Don't know what the chatter under the hood was. Any ideas?

Actually its an old model and its fuel filter is also growing old and the lines to engine and the fuel injector are not working well.So because of this issue id rise.So take it to a mechanic and change its all line and tuned it well for it proper work.
