hey i jus installed my new nos set up on my ls1 the problem im havin is that when i open the bottle the nos goes threw the solinoid without evn pressing the botton does anyone know what could be the problem any help would work thanks

 

Solenoid is stuck open. What brand is the system?

Disconnect the line after the solenoid. Try cycling the solenoid and then see if it will open properly at that point. If it does not, send it back to the manufacture or you can send it too us to let be gone through.
