nitrous cutting out

[ssms5411]

When I activate my nitrous sometimes it won't kick in until the 2nd or 3rd time I hit WOT or hit the 3200 rpm window switch. Then sometimes it will work on the first try and nothing on the second try. I bypassed my FPSS and it is still doing it. My wiring looks good, so any guesses, this is a NOS 5175 kit converted to a wet kit? I 'm stiill running the 2 nitrous solenoids as they were hooked up for the dry kit, fuel solenoid is wired to the window switch and the first nitrous solenoid. Thanks for any help, Steve

Re: nitrous cutting out

how do you have your WOT switch rigged up? I have had mine move slightly and would not work everytime due to the switch not getting pressed down far enough

Re: nitrous cutting out

Make sure your floor mat isnt hindering your pedal from going all the way to the floor which would prevent you from actually reaching WOT. Dont ask me why I would know this :o

Re: nitrous cutting out

I'm pretty sure the WOT switch is clicking, I can hear most the time. Anyhting else to look at? I'm going to try to wire all 3 solenoids off the window switch and see if it still does it. Would a cloged nitrous filter do this also?

Re: nitrous cutting out

Well, if its a clogged n2o noid, then you will run pig rich and car would sputter maybe even stall, clogged fuel noid would run lean as hell but the power would be there and very noticebly.

Could be a bad relay, bad micro switch or something with the window switch too. Check all your grounds too, those are the most common problem related to wiring.

Re: nitrous cutting out

I think I narrowed it down to the relay and the WOT switch, the window switch is working fine.

Re: nitrous cutting out

what is your bottle pressure? if the pressure is high enough, the solenoid will not open.

Re: nitrous cutting out

botle pressure is 900 to 1000 psi and when it is warm out 1200 psi.

Re: nitrous cutting out

found the problem, was the nitrous filter, was pretty clogged. I'll try running it tommorow to see how it runs. Thanks again for the responses. Steve
