Hi guys and gals just got a nice R33 GTS-T in today with some nice mods.. Picked it up from the import yard, got 100 metres down the road, stalled it pulling out onto a main road - damm that twin plate clutch, and couldn't get it to start again. It woudl crank over slowly trying to catch felt like it was flooded... Then then battery died, so we tried jump starting it but still no go... Now it seem to crank over reallly fast with no sign of firing. Even put more fuel in... Also still a slight smell of fuel... Can hear fuel pump come on as well so its not that. It also has a remote start and factory remote immobiliser. Other weird thing is that the ignition stays on for about 20 sec with all the warning lights on the dash for about 20 sec after you take the key out... Can't find a turbo timer anywhere....

I am thinking it could be the immobiliser but not sure... Will try today to take the cover off pull a spark plug out and see if any spark.. Will also maybe take the cam cover off to check the timing belt and then check all fuses as well. Any other hints?? Sorry its an RB25DET engine.. Someone also said take the oil cap off and see if you can see the camshaft turning?

I had this problem in a Soarer once turns out it was the igniter module and two fuses.... but the Nissan has the amplifier on the back of the engine....

Yea only thing I can think of is fuses or sensors..

similar thing happened on my VL (RB30det) and it was either the Fuel Pump fuse, or the CAS ( I dont think the rb25s have a CAS though)

But it does sound like some weird ignition thing.. has it got an ITC or anything? Did it start ok when you first started it?

the turbo timer might be the one like i had which was built in with the alarm system...

where do I start>???

hks 2530 turbo

apexi fuel reg

Nismo 550cc injectors

HKS front mount cooler

greddy profec b boost controller

front and rear strut braces

trac control and active LSD

four greddy electronic gauges

Nismo 300kmh dash

Tein suspension

Chipped ECU

300zx AFM

remote start and timer

Nismo twin plate clutch..

some poofy cushions as well as 3 layers of mats in the passenger side.

I had mine do that as well, when I started it, I stalled it almost immediately and then it started cranking but not a single sign of life - it was cranking very fast, not like when its starting up, it was cranking as if all spark plugs were removed and there was no compression.

I ended up tearing my hair out until I unplugged the variable cam timing solenoid then it started cranking normally and fired after a few coughs and splutters, then I plugged the solenoid back in and all was well.

I've been cranking my rb20 over the past few days trying to work out why it isn't receiving spark. This means that there would be fuel entering the cylinder's but not getting fired. Over repeated attempts to start it, could this non-burnt fuel build up in the spark plug gap so that by the time I find the problem, it wouldn't fire anyway coz of the build up of fuel? Or would the build up in the gap be minimal if at all?

I had this exact problem. Really pissed me off! had a petrol smell and it seemed the engine was pumping fuel thru even though it wouldnt start. What it turned out to be was a vacuum hose came off this thing here (in the picture attached) dunno what it is, but plugged it on and it went perfect straight away.

Sly33 what that yellow arrow points to is the air bleed tap for your cooling system, its not an air hose but a water hose.

Oops, thanks for pointing that out! Im in sydney and my car is in adelaide- i guess i cant remember the hose! when i get back ill check which one it really was :D:):D :D

    • Agreed, I've never seen a 260RS specific manual. As GTSBoy said it will mostly be stagea other than the engine loom https://www.hgeconsulting.com.au/stageaservicemanual.pdf
    • You'lll likely have to make do with R33 GTR for engine/tranny stuff, and Stagea for the body. I don't know that there's even been an actual diagram seen in the wild.
    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again
