Iam new to nitrous i have a wet single nozzle kit before the purge work fine but now i hit the purge it purges one time only about 1 second after that it wont work, bottle pressure is at 950 psi, it will purge again if i wait for 15min. Any help thanks

 

Sounds like the solenoid is bad.

 

Make sure your ground for the solonoid is good and make sure you are getting 12 volts at the solonoid when you push the button.you could be losing voltage in your button.

 

As Brent said definitely check the ground of the noid and also check your other connections as well. Also you might want to check the button out as well. One way to make sure it's not the noid is you can touch it directly to power and ground and hold it for about 5-7 seconds to see if the noid will flow the whole time or not. If it does then there is a wring short somewhere.

 

Mine does the same thing, it's mounted on the manifold and get's heat soaked very badly on the way to the track and takes hours to cool down and free-up again. Try tapping it with a wrench in hopes that it'll free up. I'm currently moving the noids to the radiator support in an attempt to remedy this situation.

 

Checked everything , it was fine , so taped it with a wrench worked again , thanks for the help
