Just after abit of advice.

My car has been sitting around for nearly 12 months, the last time it was started was 1 month ago and it was only let idle for about 10mins...

Anyway the car will not start anymore, it will wind over constantly but will not fire.

What I want to know is could the old fuel be the cause of the car not starting or would old fuel just cause it to run rough?

could be a number of things ie plugs maybe fouled and bad fuel pull a plug out and earth it get someone to crank it c if it sparks. if so fuel issues...

It's unlikely to be a problem of fuel quality. After all, the fuel is simply a mixture of liquid hydrocarbons that form an explosive mixture in the presence of the correct amount of air. While the fuel may go "off" with time, it does not go so "off" as to no longer form an explosive mixture in air.

You probably fouled the plugs last time you started the engine. Take them out, clean them up, try again.

When your trying to get it to fire, is it just making a ticking noise?

I'd be giving the battery a charge up (even if it still has power to turn on lights etc), when you kicked it over a month ago, it still might have had enough power and you only let it idle for 10mins therefore it would not have been enough to fill the battery up and you need a larger charge in the battery to get the straight 6 to fire.

Plugs seem unlikely and a lot more effort to go through to double check as a cause.

nah he said its turn over fine, so not battery,

I'd be checking the plug & spark, as mentioned, if thats all fine must be fuel supply?

my car sat since december last year, had started it twice in that time and fuel seemed to be fine, running 14psi with no knock so it shouldnt have stopped it starting, unless it had bad fuel, was it running bad when you parked it?

Thanks for the response guys, Im just trying to nut it out and it makes it even harder because Im in a sydney and the car is back in tas and Im just relaying the info my mate is giving me as he is the one who's having the dramas trying to start the car.

It really must be something minor and i was hoping to be able to find out on here what it could be before I have to pay someone to go and sort it out for me.

Yeah the car was running fine when it was last started.

Its a fresh rb26 engine thats only just been run in and had its first oil change.

The only thing thats been changed since the last time it was started 4 weeks ago is the battery was removed from the car.

A new battery was then put in the car yesterday and now it will not start. It will just wind and wind over but will not fire.

Can anyone tell me what fuses may be blown so i can have that checked first? I highly doubt that the spark plugs are fouled or anything like that as nothing has changed or been touched since it was last started.

Also I doubt its a fuel issue as the pumps prime up fine when the acc is on and after winding it for a bit you can smell fuel.

Does anyone know if it would be of any help if i plug the laptop into the Vipec to see if thats bringing up any faults or anything?

Just check any of the fuses that play a part in the ignition of the engine.

Also, if you havent already, check for loose conections with wires etc etc, Simple things like that get overlooked so often :ermm:

I would also check immobiliser if it has one and make sure no wires have come off the terminals when the battery was changed.

Good thought, but dont all immobilsers actually stop you from being able to turn the engine over? i know mine does (it was scared me a couple of times when the immobiliser hasnt detected the sensor and just been dead :ermm:)

Some will just cut fuel and spark, which is the best imo coz then if joy rider goes to steel it they will just think its a POS and wont start, if nothing happens at all they may start ripping shit apart to try to hot wire it.

      Help Understand GTT Boost Setup

      By DraftySquash · Posted

      Hi everyone, Apologies in advance if this feels like a topic covered multiple times. I'm only asking because some of the old topics I found are missing images now. I'm in the process of getting a manual boost controller (BC). Nothing fancy, just getting a manual one for now as I don't plan to go crazy with it and would not go over 10 PSI. My car is not jacked up on boost steroids to do crazy numbers. I want to understand the OEM setup of the boost solenoid and vacuum lines on the R34 GTT so I know what needs to be changed when I do install the BC. I sketched the current setup to the best I could see and it's on the diagram attached. If the boost controller 'Wastegate Arrow' goes from nipple 1 to 2. My understanding is that the red vacuum line's "F" connector-end should be connected to BC nipple #2? Nipple #1 is meant to have the "pressure source" so what vacuum line would that be? Is it the green vacuum line?  From what I have read here, the OEM boost solenoid is not used at this point. So that can come out and then I can just plug the nipple that usually connects to the blue vacuum line?  So would the final setup look something like this?   Thanks in advance. I don't want to already be knee-deep into pulling out vacuum lines before understanding this. I'm a noob when it comes to boost setups so trying to learn as I go.

      Brake pad Compound suggestion

      By GTSBoy · Posted

      Initial/early bite is a feature of.....generic pads. Things that work cold. Just put Bendix Ultimate in it. If you don't like them, it's only $3.50 wasted and an hour to change them. I've been using Intima SR, and they seem to be a good performance pad. Street friendly and able to take at least a little beating.

      Brake pad Compound suggestion

      By Vee37 · Posted

      As I implied in my post, I have NO idea what the were. But in case I didn't make it clear, the way they performed was brilliant; whatever the brand was. I think it was the compound that made the difference. And if they were Bendix, then sign me up, I want another set. I did drive down mount Ousley (just outside of the Gong) a few times, and they showed no untowards performance.   Its not the low dust that I am looking for NOW. At the time I needed low dust, but now I have no issues with dust but want the initial/early bite of the pads that were used. Yeah, the early cold squeal may of been due to a missing shim or such.  And to repeat, its not the low dust I am seeking, its the initial bite of the pads and increase in bite as  the warmed up during each breaking. As soon as I let off, I don't remember the breaks being extra sticky if I used them again soon after. But I also did not test that theory.   Thanks for the recommendation, But I would prefer to choose something specifically with the behaviour I described.   I assume that they didn't use the default compound off the shelf, as we discussed the dust issue at length. And the early squeal when cold, I have seen the sound is more of an issue with some pad compounds. Mostly ceramic, which also are said to produce less dust.

      🚨 Need Advice! Overcharged for Engineering Report 🚨

      By MBS206 · Posted

      Well, in 2007 he must have been charging about $1800 an hour. He only looked at the car for 5 minutes. And another 4 to write the report wrong, and another minute to correct it. Mind you, this was for a car that was: Stock engine, fmic (hole in drivers guard), all alloy intake and custom air box, 3 inch turbo back exhaust, lowered, and a set of 17" Advans (255/40/17 rear and 235/45/17 front). It was nothing crazy. The blue slipper wanted the "hole in the guard" engineered. But that was because he got the shits that I wouldn't "relocate the battery from the boot, back to the factory position in the engine bay"... In an R33 GTST...     Also for emissions, E85, and don't go wild on timing. It's amazing how the closer you get ignition timing towards max torque, the last couple of degrees really throw NOx counts right up. And for the huge increase in emissions, it's only a small increase in torque.
