Hey guys just wondering if anybody has had a low fuel pressure problem? My v35 was sitting for a couple of months waiting for a new clutch after it was all installed i cranked it over and it started fine but instantly started idling rough revd do op to 500 and almost stalls, there is little to no throttle response and will stall if you dont pump the accelerater to try get the revs up? Has anyone had any similar issues?

When it first ran bad it threw two codes for the vvt solenoids we cleared it and it came back straight away i bought new ones and codes are gone speaking with a couple of my mates they sugested a couple of things that it could be a mechanic friend said it sounded like a blocked exhaust but we unbolted it and didnt change anything also low oil pressure was suggested we checked it last week and pressure seemed normal except it would rise and drop with the revs when it was about to die. Then it was brought up that it might be starving for fuel and without trying to rig up the oil pressure guage to the fuel line i cant tell if it is, so i was turning to the forum i get most of my answers from for advise ??

and i havent cleaned out throttle body yet

Well im just seeing if anyone has some advise for anything i can check to cross off the list, trying to avoid the mechanics but if its too hard to pinpoint ill take it in. Ive looked through alot of threads and havent seen anything with the same symptoms as mine. I know it might be annoying to tell people the same shit but if anyone has anything i can try i would appreciate the advice ?

The usual list is:

  • Dirty fuel injector(s)
  • Fouled/worn spark plugs
  • Faulty coils
  • Dirty IACV
  • Dirty/stuffed AFM (including dirty sensor element, dry/cracked solder joints, bad loom pin connections)
  • Bad CAS loom pin connections
  • Dying fuel pump or FPCM

And to that there is a random selection of other possible shit, like the O2 sensor can cause wierdnesses, the fuel pressure reg could just possibly be stuck open, and so on.

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
