NOS Dry System Not Working?

[WS6 on the bottle]

:help: I've had the NOS Dry System for the LS1 on my car for over 2 years w/ no problems. All of the sudden it quit working. I have the toggle switch which illuminates and the system activates at WOT. No fuses blown. All grounds look good. Could this be solenoid? If so, is that an easy swap? Help.

I think you can check the solonoid by running current over it and listening to the click ?

I'd do the solenoid check first as well. Are you running a nitrous inline filter? Dirt is the #1 killer of solenoids, and if you've done a lot of bottle filling, chances are that you've got quite a few particles in the lines over the years.

What about the relay?
