Stock 454 engines, recent rebuild. SB engine will not run unless gas is poured into the carb , then will run fine and restart fine. Port engine has no problems. Any suggestions on troubleshooting?
 
Start easy, pull the fuel line and see if you are getting fuel thru the line. Was it getting fuel before the rebuild? Who did the rebuild?
 
Quadrajet carb?

Try cranking and pumping for longer than you think is necessary. Maybe 10 seconds at a time 3 or 4 times. If it eventually starts it’s leaking down between starts and needing time for the pump to refill the bowl.

If it refuses to start at all, see if your fuel pump is working by disconnecting the line as mentioned above.

Still no start? Accelerator pump.
 
Whoever did the carb rebuild may have forgot to put the accelerator pump check ball back in the carb.
