my 94 Q -- the security system is preventing the vehicle from starting!
Its not the starter, I just took it out tested and replaced even though it was good!
How to disable the security system?
I am not familiar with your year model car. Sorry. I have the 2000 OBD 2.
Is the starter spinning, turning, cranking whatever?
If no, there may well be a "relay" that sends power to the starter solenoid in your car that may not be activating. This is a Nissan setup? That has happened to me in a 240 and in that car it is known as the "blue relay". A auto electric guy fixed that for me by installing a new and separate relay. Prior I had a separate mechanic shop do the no start work for me, twice, two starters. The auto electric guy told me that sometimes older cars develop problems within the wiring harness that can preclude current flow and the easy fix was to install a separate relay, direct, to the starter solenoid. I can't help locating that starter relay, if there is one, on your car, but someone here may know where it is, or, you can consult the FSM.
But your problem may well be cured, hopefully, by following the last suggestions you received from Rex and goody. I can't help you there if your problem is the security system.
In my car, OBD 2 there is reset trick for the security system that didn't work and I had to take the car to the dealer. The starter spun like hell but no start. Now I really don't know why the security system went haywire and at the dealer we don't really get a chance to question the actual fix-it guy, but just the service writer who is just that, and not a mech. But the problem started with a dead battery. The dealer fix cost me a mere 114.00 bucks so it wasn't a killer.
Good luck
