Help. Selenoids won't fire I have just installed a coldfusion nitrous oxide system. I have a fuel pressure safety shut off switch. I have a throttle activation system and NO window switch. I have power to my toggle arming switch.
Where would be a good point to start?

close the bottle valve.
bypass the fpss by putting a wire across the two leads.
disconnect one of the wires going to the solenoid
with the ignition on, but car not running, press the WOT switch.
you should hear the relay click. if not, get a 12v light probe and see if you're getting 12v to the relay, pins 85 & 86. (light probe so you can see it from inside the car when you activate wot switch)
if that is good, put the probe across the wires on the solenoid. Hook up the solenoid and activate it. If you're getting 12v there, but the noid doesn't activate it, it can either be a bad noid (doubtful) or you used too small of wire for power / ground to the noid. Or you have a poor ground connection on the noid.
