No fule to the carburetor from the fuel pump. Is the line to the fule pump from the tank, vacuum tight? No problem with tank or tank outlet line?
If you test the pump, with line to the inlet, into a fule container, and remove the outlet line, does it pump when cranking?
Next would be to see if the electric solenoid in the carburetor is opening. It plugs the main jet to the engine. And has to have 12 volts as long as the key is on.
