R32 Gtr Running Like Pig

[edspaged2]

I managed to get my car started after how many attempts (see thread 'R32 GTR starting problem'). still didnt know why it wouldnt start previously. i let it idle for a bit and noticed a really strong fuel smell from the exhaust. i let it idle for a bit and warm up, gave it a few revs and noticed it was blowing some fuel smoke. There was also a noticeably louder ticking noise. i brought it down the road and took it for a quick lap and i could feel the power kicking in and out. I pressure checked the fuel line and its OK. so is the fuel pump. i kinda have it summed down to either being the following:

>Crank Angle Sensor

>Gummy injectors(?)

>The ECU

>Spark Plugs

>The coil packs/Power Transistor or something electronially anyway, seeing that the car wasnt starting a few days ago.

I turned the car off, only to have it not start on me again just a few minutes later! The Exhaust Temp light is also flashing and i was told that it also doubles as a 'check engine' light. Would anyone have any ideas as to whats goin on? Has anyone ever had the same problem before? This is really ticking me off now, and im startin to lose the Skyline spirit. i think i should have stuck to my 180sx........

id say probly stuck injector. ur cas wnt make the motor suck more fuel, it just wont burn it properly.

now that you mentioned it, when i turn the key to "ON", there comes a slight noise that seems to be coming from one of the injectors. not sure if it usually does this, but still not too sure why its blowin smoke which seems to be unburnt fuel if it does have a stuck injector.....

anymore ideas? :

There is a good chance that the spark plugs are now fouled due to the motor turning over for an extended period without firing (the fuel injectors would be adding fuel during cranking which hasn't been burnt). I would suggest if it doesn't improve after a good drive (eg 50km) that you look elsewhere.

I would also suggest checking ECU diagnostics and I wouldn't be surprised if the Crank Angle Sensor (CAS) is the source of the original problem judging by your symptons.

Hope this helps.

Cheers

Yep. I thought i would have to eventually check the ECU diagnostic system. I'll either bring it into a workshop which have the 'Nissan Consult' computer module or buy the program and adapter for my laptop. Cheers mate! I really should have given it more thought into buying the 32 GTR, being fairly old now and less reliable than newer cars.....

Still open for more ideas as to what the f__ck is goin on people!

could even be an AFM problem that triggers intermittently when the plug is jiggled by bumps in the road, or even the unit itself has decided its had enough.

This will make the mixture very rich when the AFM isnt reading correctly and black smoke will blow from all the fuel being burnt. This increase in fuel corresponds with you saying that the car lacks power when it happens. Also, the exhaust light comes on which means the cat is getting very hot and is prone to melting due to the unburnt fuel being burnt in the exhaust.

[edspaged2]

Yeah, the exhaust temp flashes. It flashes even when i turn the key to 'On'. Havent been able to start the car yet so i dont think it would be flashing if the exhaust is hot I will check the AFM though and the sparkies as well. Does anyone actually think it could be the spark plugs?

[Remix-]

Sounds very much like it could be to do with the AFM's dude!

[SLIPPERY]

have a look at the fault codes on the ecu...theyll tell you if its AFM, injectors etc

sorry, i dont have the number codes for the faults

[blind_elk]

Pull the cat out of the exhaust and check it hasn't collapsed or otherwise pooped itself.

[edspaged2]

Got some of the fault codes from "The Sky Is The Limit" pdf. tells you how to check codes with ECU by turning this screw on the side. theres all this other handy stuff for the Skyline too. sounds pretty straightforward. Ive heard of another method where you can bridge these two terminals in the plug for the Nissan Consult module using a paper clip or bit of wire. Has anyone done either of these methods?

[SLIPPERY]

have you looked at the fault codes yet? what did ya get?

[Morgs]

I'd baby it to your mechanic, or workshop with a consult/diagnostic equipment which can tell you straight away. RB26s are not cheap engines to replace.

Cheers

Okay, apparently the ECU's LED will mirror the dash light. Putting the key in the ignition the lights were flashing on the ECU and the dash already. I turned the screw clockwise then counterclockwise but they still mirror each other, so i assume its already in mode 2 to check diagnostics. I think what im getting is either "11" or "22". Im pretty sure 22 isnt a code at all . i have a feeling that i aint doin it right. I read the GTR manual and it seems gobbledygook to me. Has anyone actually done this manually without using a Consult?

Mate if you're near the Blue Mountains you are more than welcome to come use my shiny new consult cable.

[edspaged2]

Thanks mate, but im all the way north. Northern Territory ! i think i might buy myself the consult cable too. Too hard tryin to read the flashing LED on the ECU and dash, cant decipher whether its flashin one code or another, then it seems like its not flashing too quick or slow lol

[edspaged2]

old thread now this one is, but car still aint runnin. Have no cash being a poor ass uni student. It starts up but when i put my foot down it splutters and misses and still blows fuel smoke. I replaced the PTU/igniter but still running like the proverbial. a freind came round with tools and checked the spark plugs, and they were coated in soot, that being obvious as its blowing smoke.

What should i actually be looking at? The CAS, AFM's, something to do with ignition, paris hilton?

Ive tried checkin the fault codes but it seriously isnt working. i turn the screw on the ECU clockwise and leave for 2-3 seconds, then turn back to normal position but nothing. i bridge the two terminals (CHK and IGN) for the Consult plug but still nothin. The fuel system has already been checked. all good in that department.

when it drives it sounds as if its runnning on a few cylinders, then as it warms up it gets worse and there is barely any power. i also have to keep the revs up in case it stalls.

I have no idea what im lookin for now. any info or same experiences will help!!

well first up chuck in some new copper spark plugs even a student can afford them

ddi you find anyone up norht that has a consult cable? do you know Ron, maybe he has one? the consult kits are available as a group buy for about $25 + some soldering so try that next it will tell you what is goung wrong if it is electrical

[SLIPPERY]

poor GTRs dont like surviving on uni wages any more than a uni student does

in regard to what needs checking: its all above, weve told you. we cant do much more unless you get a reading of the fault codes or use some intuition and take apart the piping, pull out the AFM's and get them tested. An auto electrician can test stuff like coil power packs , AFMs etc if you dont have the right tools

if you cant afford the call out then it may be best to bite the bullet and sell the car. shes got a big belly and likes to eat your cash

Hey mate. I had a similar problem to you last week. If its pouring out black smoke out the back then it could be the vacuum. I was racing one night and my car popped. it wouldnt idle, it wouldnt stay, i had to keep my foot on the throttle to keep it alive. Sounded like a race car.... roooof rooof rooof. I thought i had screwed my engine or dropped a cylinder. After hours of thinking (Actually days) i came to the conclusion that it was my vacuum. That means, intercooler piping, BOVS or standard release valves, vacuum hoses to the turbos, anything to do with putting air into your car.

You also mentioned that you can hear a loud tapping, I heard the same thing. that was fixed as soon as I fixed my vacuum problem.

Anyways what i found out was that my inlet side on the Intercooler piping had come off, yes come off. This was making my gtr sound like a race car.

What i would suggest is to look into your pipes and BOV's and see if they are normal. BOV's pistons can seize due to age and cause bad vacuum. Piping can come off due to age.

If its your BOV's try to find stockies and use them, if its your piping, you might get away with just replacing the worm clamps to new ones and tightening up.

Good luck. ill keep checking this to see if you get anywhere.
