The plugs can be any brand?

But most used are NGK?

Waiting for shops to open and hoping the rain holds off.

So, 2 options comments have given me:

BCPR6ES 0.8

BKR6E 0.8

Whats the difference?

Well,

All fitted, everything back together.

Tried to start it up, same problem.

But this time, i think i may have found the problem.

While tightening with the allen key, i dropped it into a small gap and while i was getting it out, the injector rail was starring right back at me, all injectors were a bit dusty and dry except one which looked like it had petrol running from it. Didn't really think about it, then got the allen key out, then had a closer look at the 5th injector.

Got the keys, tried to start it up.

No luck, went back and checked the injector, definitly petrol coming out of it and it was hissing, a leak.

Could this be the solution?

Loss of pressure/loss of fuel?

Also, with this problem, will it be just the o ring or the injector itself?

Edited by Owgasm

I'd expect the engine to at least start and run on only 5. Might be a bit WReXxy, but should still run.

But it's not a good sign to have fuel leaking from an injector. Should get them checked out. Best case, it can be repaired, and all 6 can be cleaned and flowed. Worst case, 6 new injectors on the shopping list.

Yeah, i'm still unsure why it didn't start, but i pulled the injectors out while i was at it and the o ring on the 5th was split.

New O-rings for all 6 and see how it is from there.

I still don't think this will be the solution, but i hope it will be.

Btw, anyone know what size the o rings are for the injectors?

Forget the timing belt if everything sounds normal when your cranking it. If it was broken you would know about it! I had a feeling fouled up plugs wouldnt stop a modern day EFI engine from firing and at least running rough. The injector leak will just be that o-ring but as you mentioned i also doubt it will be the actual cause of no start, just rough running. Make sure when you refit the injectors you put some vaseline on the o-rings to spot them from getting cut.

So next off you should check that you actually have spark like i previously mentioned on page one. Also think back to last time you had it running, did you do anything to the car? Anything at all.. the smallest thing you may not even take into account could be the culprit :thumbsup:

Good luck mate

Yeah, i don't think theres anything wrong with the timing belt.

Everything sounds to be smooth. Just doesn't fire.

Yeah, i should have checked the spark while i was at it but am not 100% sure on how to do it. So was hoping that the spark plugs were dead.

The last time it was running, it was reveresed down a hill and driven back up, a few times like this to clean the rotors and just give it a bit of flow through the engine.

Next step to check for the spark.

Are there step directions in the forums?

Thanks for helping everyone.

Buy yourself a spark plug lead, plug 1 end of lead to coil pack, other end to your spark plug, then ground the thread of the spark plug on the block, or the massive hook usually on a motor, then have a friend turn the engine over, you should see a nice blue or white spark from the plug.

For the injectors, there is a plug you can buy, which you plug onto the injector lead and again have a friend turn the engine over, and the plug has an LED in it, which will light up if there is any voltage through the lead (if the injector lead is presenting a pulse).

For the injector plug, you need to immobilise the motor from firing and possibly starting, reason is, with an injector unplugged, if the engine does fire, you will farily quickly roast your cylinder from the spark plug firing.

hi, I had the exact same problem. I have a r32 gtr and I don't get the opportunity to drive it much at all. I take my car for a quick blat around the street then park it up. I do this once a week if i can, a bit like your self. Sometimes i had to jumpstart the car to get it started .

Then 1 weekend i went to drive it and it wouldn't start so i jumped it no joy then tried to push start it still no joy.

Then i checked to see if it was getting fuel to the injectors cause i heard the fuel pump like yourself, but no, I was getting fuel.

I checked spark that was all good to.

I even replaced the spark plugs and coil packs just to be sure.

In between checking I had changed the battery three times with 3 known good ones this still didn't start my car.

In the end I ran out of ideas and put the car on a trailer and sent it to my local tuner he fixed it in 2 mins flat it was the f@!#ing battery. He put a brand new one in and it started first go. To this day I still do not understand why my car didn't sart with the other batteries because they all started my other cars fine. (all had 12v)

Hope this helps.

""Pull a plug out (check plug condition while your there) and connect it into the coil while also earth it on the head next to the spark plug hole. Easiest way to do this is to get a HT lead and connect one end to the coil where the spark plug normally goes and the other end to the top of the spark plug."" - From Deren

Ok. This is what i read:

1. Pull the first spark plug out.

2. Take the coil off and plug it onto the spark plug with the cables all still connected to the coil.

3. (not so clear about this part) - Hold the spark plug while its touching the head (anywhere?).

4. Get someone to try to start the car and watch for a spark

Is this right?

The fuel i am sure is in the rail as i could see it bubbling trying to exit through the injector seal.

Someone said on the forums, that i only need to check the first? If the first is sparking, the rest will aswell.

Edited by Owgasm

Yeah thats pretty much right, most likely if one is firing the rest will be and you will at least be getting a splutter when you try to start it. Best not to hold the coil while your cranking it as you can get a bit of a shock from the ignition system :) Just rest it down next to the spark plug hole and shade the area so you can see the spark if there is one. Like i said if you need a hand im happy to help :)

Deren

Perfect.

Yeah, thanks for the help :P

Will let you know if i need help. But your description sounds easy enough.

Anyone know the size of the o ring on the injector?

I don't want to match it up, i want exact size when i go to a supplier.

Where do you get them from? Nut and bolt store? i've gotten them once but can't remember where it was.

Cheers.

DOES IT ACTUALLY SOUND OK when cranking it over??? I cant hear it!

Anyway, what about CAS, is that goosed.

IMO.. it would at least kick if even on a few cylinders if it were the plugs!!..

Why is everyone so completely sure its the plugs that are the root cause.. just by the info I can glean from all this, there has only been speculation about plugs.. which, to be honest are pretty damn reliable in this century.

Lets just sit back a little here, and work the problem...

Not firing...

Is there an immobiliser fitted?

Is there gas in the tank?

Is there 1 meagre spark from one of the coils, or any of them,, simply unscrew it, hang a plug out of it and see?

Just basic starters, then work from there... or is this real?

Battery would not be the cause, mine has cranked... and fired on a very low charge, so much so it even amazed me.

QED.

    • Can perhaps see how the R33 appreciators would think so.  
    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
