there is no fuel inside the tbi, is there anything like a switch that will prevent fuel from flowing if it is turned upside down? i took the intake off as one piece when i rebuilt the motor. it got moved around.

When you turn key to run do you hear the fuel pump come On if so check the fuel pressure there should be fuel on the line
