So I converted my dry system today to a wet kit,
hooked everything up went to test it out and imidiately
noticed that the fuel silenoid s not working a/f shot up to 14.5/1
I run back home take the cover off the fuel silenoid cuss at it for a minute
put the cover back on, What do you know it seemed to work just fine
so my question is what is going on here ?/ I would hate for it to malfuntion
sometime while going down the track

FPSS, a Window Switch, and a wide band.

whats this mean ??
I would say it was not a wiring prob.

whats this mean ??

fpss = fuel pressure safety switch
window switch = only allows the system to spray within a designated RPM range (for safety)
wide band = wide band O2 sensor - to monitor your a/f while spraying

and I have all the above, knew what he was talking about but didn't know his reasoning, why would the Nitrous side work but not the fuel side when they are wired together with the nitrous wires being tapped into the fuel wires

Sometimes the solenoids just stick a little when they are new... why? I don't know. Mine stuck for a couple times during testing, and now works just fine.

A good thing is to ALWAYS test both solenoids (but especially the fuel solenoid on a wet kit) while the lines are disconnected and the car off BEFORE running it down the road and spraying it into the engine - after new install, of course, not every time.
