Default please need help fast! leaving in 30 min

ok ive been having a problem with my nitrous system!

i replaced the relay and checked all wires, checked both solenoids to see if they work and they both do.

now the problem is when i go to spray, nothing happens. The Fuel noid still works when wot is clicked, but not nitrous!

could my FPSS be fried or what?

also could i bypass it for now till i get a new one?

please repond quickly..money is depending on this!

Randy

if its wired properly a FPSS shuts the nitrous off in the event of fuel pressure drop...has nothing to do with the fuel solenoid..that'll still work. when mine malfunctioned it would still dump the fuel but no juice. im not expert, i could be wrong, but im just talkin from my own personal experiance.

Should have both noids running through FPSS. Why would you want fuel pumping into your intake when your having a malfunction in your system, just asking for a big boominski.

Actually, that's probably improperly wired. The FPSS, when properly wired and activated, should shut down the entire nitrous system. Including both fuel and nitrous noids......

well im glad you found your problem...

as far as wiring, i dunno, maybe my system isnt wired for both noids...im also running a timing tuner whch may have something to do with it. i didnt wire the system up, my friend took that task on and hes wired up plenty of nitrous systems so i trusted him to do so...ill have to check into it.

It's as simple as wiring both noid grounds through FPSS, then any fuel problem shuts the ground path down for both n2o and fuel.

both solenoids should be wired in parallel.
