weber help wont start

hey guys any help or ideas

just installed the new weber took all wiring and vacum out of truck accept vac adv and went to start the truck no go it has spark and theres def fuel going into intake cuz i can see it

every first time u go to crank it it sounds like ti wants to go and then nothing any ideas adjustment i can do or something lemme know thanks anthony

also the port for the fuel vapor can can i just plug that off and then plug the line that runs from the tank up or can i run the one form the tank up into the carb or do i have to run the can cuz i wud rather not

If that does'nt help PM me or post back up. PM would be a better idea though...

also on your lines you just need the main fuel line. plug or remove the others and use a vented gas cap.
