I just installed my nitrous kit again.. problem is the nitrous isn't spraying!? could it be the solenoid??

Elaborate on your setup a bit so we might possibly be able to help you.

Did you fill the bottle?
Did you open the bottle before spraying?

Too many questions...

:shrug

COuld be a dying solinoid, or one with a weak electrical connection.

or if you dont close it between uses (not in one night, but over days) the nitrous will leak out slowly.

do you have a heater, a pressure gauge, remote opener?

Ok close the bottle activate the switch and then flip the wot switch in the engine bay, listen for a click from your solenoids. Dont make it click too much because you could potentialy fry your solenoids. Just do it a couple of times to see if they are opening. If there is no click check your wires and your grounds, You probly wired them backwards.

ya.. bottle filled pressure @ 800, opened, armed, and everything gtg. i've sprayed before.. i hear a click only on the fuel solenoid and not the nitrous.. kit's been sittin in my garage for about a year untouched.. so think it's the nitrous solenoid? think it's time for a new one? couldn't be anything else huh?

just check the connections. If they all look good than its time for a new soleniod.

Take the solenoid apart and clean it. When I was running nitrous I was purging and had the valve stick open. So I turned off the bottle and cleaned the solenoid. Worked great after that.

Ok.. that clickin noise that i heard was not from the fuel solenoid but from the relay itself.. i tested each of the solenoids individually straight onto a 12+ bypassin the relay and it works. Seems as tho it's not gettin power to open the solenoids.. hmmm..ima go pick up a volt meter.. unless u clever guys kno of another way to check for continuity on a wire w/o a meter?

i can't seem to find the problem!? all my wiring is cool.. there's a current in every wire.. how come my solenoids aren't gettin power?? Shit's armed, micro switch activated, yet still not gettin juice to the solenoids to open.. getting really peeved here.. think it could be the power relay.. cuz that's the only thing i could think of.. any other ideaS?

like you said probly a relay then.

Do you have the fuel safety thing?
