65 dart 273, No fuel from pump to carb!

Filled both with a syringe and have a hose going from a gas can to the fuel pump. Still no start. Pulled a timing light out and don’t think it wouldn’t start if it was a little off. When I pull the engine to reseal everything, I marked the balancing pulley so I’d put it back the exact same way and never turned over the engine so I don’t believe it could be that far out of time. Not
If no fuel going to carb, its most likely Fuel pump.

Any fuel at out port of fuel filter?

If yes?

Try putting a little gas directly into carb? Make sure the throttle blades are open when you do this.

This effectively bypasses the carb as you are putting gas directly into intake manifold.

If the car tries to start or starts briefly and shuts off problem is Carb related as long as there is fuel in the fuel line going into the carb.
