86 Nissan 300zx TT

[Exia]

Ok, I am in the process of buying this, but the problem he is having is that his dads mechanic unplugged something and now when you attempt to crank the car the secruity light flashs and the whole thing dies any idea what he disconnected?

Welcome to nico!

First thing is that a 1986 300zx was not twin turboed from the factory. So you need to figure out exactly what you have. Then we can help you!

If it turns out your car is not a Z32 (300zx 1990-1996 USDM market) then i'll move the topic to the appropriate section.

[Exia]

well from what I was told the original owner bought all the extra's it has every possible option. But it is a TT set up but would it even matter if it was tt or st? Only thing I know is he uplugged something and just want to know what he unplugged?

[NolimitZ32]

Yes because the Z31 (which the 86 is) was a single turbo vg30e and the Z32 which was 90-99 was a TT and ran a VG30DE. everything on the two cars is different so to help you we need to know which of the two you own.

[Exia]

ah ok its the Z31 they added another turbo. so yea ok its the stock single just with an aftermarket 2nd turbo. But the car i was told ran fine even after the 2nd was added, they had a guy unplug something cause they were afraid it would be broke into where they lived, now it wont do anything. kills the whole dash as well have to unplug battery for 10 minutes before you can attempt to start it again. Someone said check the relay on the ignition switch?

[NolimitZ32]

I gotta see pics of this TT Z32 setup, thats a pretty rare thing to do to a Z31. Also pics of any aftermarket wiring or switches may help. off the top of my head I cant think of anything that would make the car behave like this, especially for 10 minutes.

[Exia]

well i dont think its a Z32 setup, this would be my first 300zx and i think i posted in wrong thread its the Z31, they just twined the orignal motor. which is the 3.0L dont know if this helps.

[NolimitZ32]

Z31 and Z32 are both 3.0, the Z31 is SOHC, the Z32 is DOHC

Ok so this needs to be moved to the Z31 Section.

I've gotta see pictures of that. Please post some.

[Exia]

Ok I am thinking about buying it, I dont have pics If ui cant get help with this security issues im not even going to bother. seems like this is getting off topic. its the SOHC. so any ideas on the issue? where i should look? or should i not even bother with the car?

[evildky]

lets just assume that this is a bone stock 86 300zx turbo, wiht the stock vg30et

the car as it sits won't start but has a security light flashinng, this sound about right?

and you think something got unplugges to prevent it form being stolen.

first thing I'd do is look for anythiing unplugges, starter trigger wire, is the one thing that comes to mind that would keep the car form cranking, that or a neutral saftey or clutch saftey relay

if everything si plugged in, is the starter getting the singnal voltage? there are 2 wires ont he starter, a large heavy gauge wire leading from the battery and a smaller trigger wire that gets how when you turn the key (if it's a manual trans this first goes through the clutch saftey switch, if it's an automatic then it goes through the neutral saftey circuit) so can we verify that you are getting trigger voltage? and f not wiht the key in the run position you can arc power from the main lug to the trigger (ideally with a length of wire and not while laying under the car (and in neutral(or park) with the ebrake on))

[AZ-ZBum]

put key in door.
lock.
unlock.

If car still won't start, then what is it doing when you turn the key?

Have you checked ALL the fuses?
Have you tested the battery to make sure it has more than 12V?
Does it make any noise when you turn the key?

And back off topic... Are you sure it has two turbos? Do you know what a turbo looks like? Can you physically see them both?

The trouble is, if you say there are two turbos on the car, then who knows what motor it really has and it could be something completely unrelated to normal diagnosis since it won't necessarily be like any other Z31.

[Exia]

Thanks man, thats the most help i have finally gotten. and yes close enough, I was told when you attempt to start it thats when the security light would flash than shutdown everything. But you have a good read on it. and it is automatic ( would have liked the 5sp but oh well ). I am going to take the car and hopefully once it gets here, ill beable to give more information but I will look into this first. But I do have another question? IF something was unplugged would a Diagnostic computer pick it up? or the self diagnotics from the dash?.......... And yes I know what a turbo is I use to own a 91 240sx with a KA24DE swap with a Banks T4 tial waste gate and a HKS SSQVIII with Nismo FMIC.. and again only pictures of the car i have seen is the outside. and the interior no engine pics he says he is 100% sure its twin. but now you have me wondering.

[evildky]

my money says seller is an idiot and it's a stock turbo car (it does have a "c" in the 4th position of the vin right?)

[Exia]

No has H in 4th spot

[evildky]

then it's not a factory turbo car, are you sure this har has any turbo(s)? because it didn't leave the factory with one

[Exia]

Yes after you mentoned the vin I called a local dealership, they looked it up. and its coming back as a GLL with a VG30E and 4sp automatic.. I have also just now texted the guy and asked for a picture of that engine. but I will list what the car has here..... T-Tops, Digital Dash, 16in Rims, Leather Seats, Premium Sound, tons of controls on steering wheel.. Does this sound like a GLL or was those added?

[evildky]

z bum would know better than I, but I'm pretty sure the n/a's all came with 15" wheels

I'm not sure what all was included wiht the gll but I think that it included the digital dach and steering wheel controls, and leather

this whole thign has me puzzeled, where are you? where is the car? whay are you looking at this particular car?

[Exia]

Im in KY, and i need a car and this one is cheap, especially if thats all thats wrong with it. To be honest I always wanted a 300zx more like the 90s 2+2 but ill settle for this.. But I myself am getting more and more confused as well. But soon as I get a pic of the engine ill post it.

[evildky]

where in KY? I'm in Louisville, and my Z31 is for sale, it'll run circles around a Z32 TT, and a 2+2 is soo heavy and slow, it's nto even in the same arena

You can also look that information up yourself on http://www.thezregistry.com.

I hope he's not asking for much if he can't even figure out why it doesn't run. Should be less than a grand.

16" wheels (don't call them rims, that's ghetto slang) are not standard on the non-turbo models.
All GLL models (except the 1984 model year) featured steering wheel controls for the stereo (4 buttons and a volume) and cruise. That's standard.
All 84-86 GLL models featured the digital instrumentation.
People who aren't familiar with the Z line (or love American cars) typically think TT means T-Tops. Maybe in other circles it does, but not when talking about a 300ZX. I'm guessing he's confused and typically drives a Camaro.

BTW: A dealership wouldn't have added a second turbo to a factory Z31. They wouldn't have known what to do. This was never even an option, so even if the car had every available option at the dealership, a second turbo wouldn't have been one of them. Seller is clueless. I hope he isn't asking for a lot of money.

[Exia]

Yea it just now came to light, the body and badging says Turbo but the motor is says V6 3000 thats it. but the funny thing is it does have the factory boost gauge weird but as far as price.. as of right now my 1 and only means of transportation 94 Suzuki Katana 750 but im having to do some sacrifices for family reasons. Thats why I was trading it but i dont think I will for a base model N/A that doesnt run
