Zex Help

[brose]

Ok my zex kit was working fine I have a wet system for my rx8. It have went through about 3 bottles. But today I just stop spraying. The boxs turns on with a green light, I hear the sileniolds clicking and a can purge. I tried made about 6 attempted passes today but no performance gains and bottle pressure did not go down. Any ideas on my I am not spraying? I also have a window switch that was working properly and still appears to be registering the right rpms

What was the bottle pressure at when you tried to spray? Also have you tried just pulling the line off and spraying it just to see if you have nitrous and fuel flow or not?
