Need help on my NOS System I need some troubleshooting help on my nitrous system. When I went to the track last week, my nitrous system didn't spray. So I got messing with it today. Basically when you hit the switch the relay clicks but nothing happens at the solenoids.
What I have done to test:
I have traced all the wires and all look fine
I changed the fuse out
I By-passed the Fuel Pressure Safety Switch.
I have checked to make sure nitrous is getting to the solenoids
I have tried all I can think of. I can't remember if the solenoids click like the relay does or not. But it isn't clicking or anything right now. I have the NOS 5177 dry kit with the two solenoids and it seems that neither are doing anything. So I though it was a ground, but all my ground and power going to the relay seem to be fine and the fact that the relay is clicking makes me think it is a short to the solenoid. Could the relay be bad and still click?
This system is right at a year old and has only been sprayed about 5 times.

I turn the bottle on (have 950psi), I by passed the Fuel pressure switch, I walk to the front and push on the WOT switch. Relay clicks nothing else happens!!

i will tell you this.... i have had problems with the nitrous solenoids from nos from day one..... it seemed like every year i was calling them for a new one or the dang rebuilds for them.. your problem most likely is a faulty solenoid...

If you are in doubt about your noids you can try touching fused 12v directly to them (bypass the relay) and see if they click/spray.

I went back out after typing this and thought about using a multimeter to see if the relay was kicking out power. Well guess what....It wasn't. A quick trip to a friends house to get a new relay and boom everything worked. I even forgot about just tapping 12volt to the solenoid and seeing if it worked (Which my buddy asked if I had done...duhh). I didn't even think that even though the relay is clicking that it could be bad!! Ah well, now I know.
Thanks guys!!
