Nitrous Oxide - BAD Fuel pressure safety switch??

I think my fuel pressure safety switch has gone bad. Just got my MSD window switch put in an everything seems to work but it just wont spray. When we bypassed the safety switch the selanoids worked fine. when we didnt bypass it they wouldnt click. Do these pieces go bad sometimes?? it is a NOS 5177 Dry kit.

FPSS are perty notorious for being unstable or bad. What brand is your FPSS anyway?

It came with the NOS 5177 kit.

Im not sure if it is ade like the one from NX.If it is you can pull off the rubber plug on the end and set it to work

If you can't adjust it, bypass it untill you can get one that is.
