Yeah hey guys, lately the skyline is getting really hard to start, I can hear the starter motor wind but the engine just won’t start and run. Eventually after 3 or 4 cranks the car will start but yeah, pissing me off a little.

So I took the car to the auto leco and they took and cleaned the spark plugs as well as reduced the gap to .8 then started on the injectors cleaned the crap on the bottom of one before they ran out time. This cost $175 and there is no improvement what so ever! They said they will clean the other 5 injectors but that’s going to cost $500!!

Has anyone else had this problem before i spend heaps more?

Car:

R32 GTS-t Japan Import

just bumping this up for pat, basically, it turns over but doesn't fire. You need to do crank it for a few seconds, stop then do it again the. Touch the acc pedal then try again, and it'll fire. It doesn't have the prob when it's warm ie.itll start first go if you start it up again after you've been for a drive

How many km's does your R32 have on it? I know this is a long shot, but you could be losing compression as the worst scenario case. 500 seems a bit steep mate, you can start looking at buying new injectors at that price. Maybe change the plugs and have a look at the coilpacks. What's your oil pressure like? and level? Just a bit of looking around, hard to know what it could be, but by the sounds of it you must think it is electronic taking it to an auto electrician. Try a local mechanic or a reputable mechanic you can trust (if you have one) I haven't got one yet...

Do you work on your car much?

Maybe start tinkering and gain some general knowledge in how your car goes (sry to sound blunt) can help in the diagnostic stages.

Hope that helps :rofl::)

I have this problem. not as bad as yours though. mine starts then stalls. my mechanic my injecters are leaking slightly and he said it will be hard to start when cold. mine is also fine as soon as it starts once, then is fine for the rest of the day. its just first start in the morning is rough.

Good luck with it

with regards to the 500 being steep, and being able to buy new injectors for that price, thats exactly what i said. previously it had a misfire under loading, in boost, at about 3-4k, but that was resolved by re-gapping the sparkplugs like pat said. I also suggested it may be coilpacks, but seeing as how the plugs fixed the miss, im leaning towards injectors.

The other day when we went for a cruise, oil pressure seemed a little low, but i dont see how this would affect the start up...

Fuel pump!! Change it and the filter.

nah, it has a pretty new aftermarket pump, but the fuel filter might need a change

So many key board mechanics. Meaning well = $

I own an R32 and a mechanic. You need to describe the problem as a cold start issue to anyone you see about it. My cold start has gotten progressively worse since i had mine imported. It used to roar into life when I first bought it and i've only ever treated with the best oil which I suspect has been most R32's undoing. Now when you start it first thing in the morning it will cough and fart for a few seconds until oil pressure builds up properly through the motor.

So, what you, me and everyone else is dealing with is 16+years of redline abuse causing the lifters to bleed down gradually overnight. When your lifters are down your valves don't open. no air and fuel which results in no bangy bangy. When you are cranking you are effectively waiting for the lifters to refill with oil to bring them back up to operate the valves.

Just an idea anyway. hope that helps.

P.S. if you take it to a mechanic A. make sure it is a good one that knows skylines and B. tell them exactly what happens and when. (You cannot leave out vital information like it is a cold start issue or you are wasting thier time and your money) and C. you will have to leave the car for several days possibly, for them to experience it themselves.

I regards to the oil pressure I happen to know someone with a black S2 R33. His oil pressure is quite low and at idle can stall. The car has something like 90XXX km's or so on it and seems to be in farely good nic. How long since your last oil change? Oil gradually becomes thinner as time goes on as you most probably know, which can result in a gradual decrease in pressure. Get some new oil in there :(

I plan on gapping my plugs to .8mm sometime today, not running extremely high boost, but my idle is a little rough.

The oil change will probably not fix your problems, but it can play a factor in an old engine I think, and will help to rule the whole pressure thing out if your leaning that way. If you have recently changed the oil or it is within 5000km's, then don't bother. I would definately put some money on the fuel filter though. I used to get missing and it seems to emphasise the effect with an old filter (going to change again soon, being a bit tight tho because I just bought a new socket set). From what you have said, the fuel pump. etc. is new, so maybe there is restriction possibly caused by the filter - although not neccessarily, because the problem is cold start related, which can lead to questions relating to the age of the engine and the wear. etc. Do some good researching on the rb's and find out what might be problematic in older engines :rofl: which is all I can say.

Could be time for new coilpacks. Investigate the issue further, not really too sure as to what it might be, maybe try PM'ing some of the more experienced members or search for symptoms on the site. Look at the more specific details which may help you cut the variables down on what could be causing the problem, specific sounds.etc.

Hope you can find the problem and fix it mate.

If you have any clues on bucket seats - check my thread :D ha ha.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
