I've got a 94' 300zx with some crazy electrical problem.I believe it's the security system. I'll be driving down the road and all of a sudden the headlights start flashing. If I turn the car off, it will not restart.I've had to pull the fuse for the anti-theft system so the car will start. When the lights start flashing, I turn on the headlights and things are fine, except when I forget to turn them off and kill the battery. I've been told that it's usually the pins in the locks need cleaned. Done that. Is there any way to just disengage the system?

Have some one who installs car security systems take it out and put a new one in
