My Rb26 Wont Start... Why!

[PAV34]

Those plugs are absolutley rooted.

Get BKR6E NGK Coppers, gapped at 0.8mm - no problem at all, I usually change them with every service.

[Owgasm]

Alright, sounds good.

Put the car on charge over night will buy the plugs tomorrow morning and see how i go.

Hoping they have the 0.8's instock.

[blind_elk]

If they don't have 0.8s, buy a feeler gauge set as well, and gap them yourself.

[Owgasm]

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?

Alright, took the plunge, got some NGK BKR6E 0.8mm from Autobarn with 20% off

$19 for 6.

[Owgasm]

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?

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.

[Owgasm]

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?

Snapped Cam belt usually happens first thing afdter a long run if it is weak. Check it!

[Godzilla32]

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

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.

I made a post on how to check for spark and fuel on the first page. Check that out if you like. Or if your in brissy i can help you out one day.. Lemme know mate.

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 June 9, 2008 by Owgasm

[Godzilla32]

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

[Owgasm]

Perfect.

Yeah, thanks for the help

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.

[Owgasm]

Capalaba. Geez, no o-rings anywhere.

Ok, whats the part number from nissan?

Would they give out the size if i call them?

I do know where to get o -rings but need size.

[bnr#@]

Have you checked the basics like all the fuses? A major problem that stops the car from starting wont just happen without the car being driven at all. My $ is on the ecu fuse or there abouts

[Richieb]

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.
