hey guys

i have a r34 gt-t with a few mods and it has the power fc installed.

the car has been playing up since i purchased it..

the car just doesnt want to start sometimes..(if i play around with it for a while it will finally start) or while im driving it just stalls on me n wont start for a while again..

at first i fought it was the after market imobiliser playing up so had it taken out but still doin the same thing..

when the starting issue occurs it sounds that the car wants to start but it just wont..(the problem occurs randomly car had been good for 3weeks than the past week played up nearly everyday)

any help would be great..thanks guys..

could it be any of these ideas and if so how can i check my self:

-standard immobiliser

-fuel pump

-fuel regulator

-power fc ecu

-earth problem

could be the crank angle sensor. it isn't registering that the car is turning over so it isn't injecting fuel or igniting it.

could also be the fuel pump though. to rule out the CAS, next time it fails to start, pull one of the spark plugs out. if it is wet then there is fuel going in, but for some reason it isn't sparking. that means fuel pump is ok and CAS is ok. if it is dry then more than likely the CAS is faulty, but could also be the fuel pump. to then test the CAS you need to remove it from the engine (keeping it plugged in though) and spin it by hand (with the key on). if you hear the injectors click as it spins then the CAS is fine and it's more than likely the fuel pump, or an ignition issue.

    • 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.
