i have a r33 gst

and a few months ago stopped starting

put a new battery still doesnt change

jump start it using the terminal in the front

and bang it starts

today did all the checks

ground seems fine as multimetre reads around 12v when getting reading of the terminals

battery is at 12v

the big wire from battery at boot fuse box reads 12v

and the 2 terminals at the front also read 12v (maybe 11v should i be worried?)

when i start the car the voltage drops to 10v (but nothing lower - is that a sign somethings wrong?)

any ideas whats wrong

or any previous experiences id love to know

also if you need more info feel free to ask

really stumpd at the moment

as i thought the whole time something was wrong with the wiring from boot fuse box to front fuse box

but that doesnt seem to be the problem if its reading practically the same reading

maybe more information about the 'not starting' bit.. do you get lights up on the dash, does the starter motor turn the engine at all?

the terminals must be contacting well for enough current to pass to kick the starter over. accessories that draw little amps might still work but if the connection isn't very good then you won't get the solenoid clicking or the starter spinning.

my advice would be to remove the terminals and make sure you dont have any oxidation or corrosion interfering with the connection.

Also a flat battery will sometimes still read 12v, the best way to check the battery is with a hydrometer.

Clean the shit out of your battery clamps with contact cleaner and a wire brush.

If she kicks over with jumpers on - it will be a battery related problem.

I had this same problem a couple of weeks back and it was the battery clamps (not terminals on the battery but clamps that come on wires connected to the car) that were dirty.

The only reason yours fires up with jump leads is by luck - you have clamped the jumpers on to points of the battery terminals/clamps that aren't so grubby.

To be honest mine didn't look that dirty but after they were cleaned the car worked perfectly so yeah - i'd be starting here.

ok have cleaned the terminals

and think clamps (do you mean the clamps as what u put over your battery right?)

ive had a similar problem before so did do that

forget to mention that

and i did take a reading at the clamp as well - still said 12v

battery was replaced with brand new one

still no difference

when trying to start it clicks but doesnt crank

and also everything else turns on fine

hey man can you start it up with a jump then unhook the other batt and tell us what voltage the batt running the car is reading at?

what sort of voltage drop are you getting from the boot to bonnet, you mentioned 12 to 11 in your original post? that sounds like it could be a loose/bad connection somewhere

as I mentioned a battery reading 12v with no load on it doesn't mean anything. if it started with jumper leads off another battery, then everything is pointing to your current battery being dead. that *click* *click* is the solenoid on the starter motor having barely enough amps to engage itself, let alone enough amps to spin the starter motor.

Check the earth to the starter and Possibly clean the ends so it has good contact with the starter and chassis

If it's around 14v when the car is running your altenator sounds alright. If the car drops below 8v I think it is then your battery is prob stuffed. Did you get a battery with the correct cca for your car? Might not have enough amps to turn the starter

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
