I have recently bought a 86z non turbo manual tranny, the people I bought it from had it sitting for about 2 years without a battery. They say it runs but when I try to start it the engine rotated but does not start and the security light blinks... does having the hood open affect this? if so how to avoid.
you should prob get rid of all the gas and put new gas in, 2 year old gas prob wont work too well, and the hood being open wont make a difference. u should prob change just about all the fluids after 2 years of just sitting
pull em out, reconnect the plug wire, and ground the the part that screws in, they make a tool for it that makes it really easy. then just watch the plug and see if it sparks
yes the security will keep it from cranking, not keep it from rolling .....in most
most models security kills the fire to engine not the starter its self not totally sure on this age nissan though............easy way to check spark without shocking the mess out of your self is to make a ground wire (just clip or tie a piece of wire [stripped end ofcourse] to any bolt that goes into the engine.) and check for spark at the distrubutor hold onto the insulated part lol. definately get rid of old gas, you can deal with the other fluids after you make the engine crank up and run.

cough *BS* cough.
Almost every alarm kills the signal to the starter. That means that the starter will not fire. It would be terrible if your alarm started malfunctioning while you were driving and killed the engine. Like, say when you were in the middle of turning left in a busy intersection.
If the starter is engaging and spinning the motor, then the alarm is not the problem. So no. Having the hood open (or any other part of the car) will not cause the engine not to start. It's something else.

Well Thursday I will be getting a new battery and a big bottle of starting fluid and then I will try to trouble shoot(or put several 38 rounds in the engine block)
I've towed far to many cars that would roll but not crank because of the security system malfunctioning. The Cranking is a mechanical switch/linkage mechanism in the dash. It is far easier for manufacturer to interupt spark. Now aftermarket security systems are a whole different ball game.
anyway in my 86 300zx NA until today the security fuse was missing from the fuse panel (driverside kickpanel) and my car cranks and runs just fine so you may try that on yours pull the security fuse, as best as i can discover the only thing that does is make the little security light on the dash blink.

What the hell does rolling and cranking have to do with each other? Rolling a car around doesn't require the motor. It just requires the brakes be off.
And what does towing have to do with either of that? You don't even need to start the car to tow it.
How is interrupting one signal different from interrupting another signal? It's still one wire to "cut".
And NO! You ARE WRONG! GO out to ANY car out there and try something. Set off the alarm and try to start the car. Note that almost no car around will engage the starter.
ESPECIALLY don't challenge me on how the Z31 alarm works. I'm VERY familiar with a WORKING Z31 alarm. All of mine have perfectly functioning stock alarms. One of them also has a perfectly functioning AFTERMARKET alarm that I installed. And part of the installation was interrupting the starter signal wire that went from the ignition key to the starter.
Now there are (or at least, there were) a couple aftermarket alarms that would allow you to start the car and it would run for a few seconds. Just long enough to get the car out of a parking spot and into the middle of traffic. At that point, it would turn off and you wouldn't be able to start the car again. It was designed to attract attention to the person attempting to steal it. I always thought it was a stupid idea.

And here we have a sign of how you don't know what the hell is going on with the stock alarm. Thank you for letting us know that you should not be giving advice on this subject. With the fuse pulled, the factory alarm does not activate, arm, or do anything but take up space.
