Hey guys my names christon and im new to sau so first off forgive me if this is the wrong thread for this post :sweat:

I recently sold one of my cars and bought my girlfriend a R34 sedan. i left it entirely stock apart from Bc coil overs its na and auto. its been a dream daily up until a couple of days ago my girlfriend was driving and apparently all the dash lights came on and the stereo cut out but it came back and didn't repeat itself during that day later that night i took it out for a drive and as soon as i jumped in i heard what sounded like interior fan flaps etc. cycling and my interior light was flicking on and off i figured the leds could just be on there way out so i ignored it.

when i arrived at my destination the interior light didn't work so i thought they finally gave in but my central locking wasn't working. i thought weird ill check it out later went and grabbed a bite jumped in my car everything was working again put my key in as usual one click and bang no electrics at all no hazards its like someone disconected my battery checked my battery since its still new still has 13v checked fuses and relays i couldn't see anything out of the ordinary i waited and faintly my interior light came back on dimly cranked and no electrics again waited waited waited eventually i had full power and the car cranked and started drove home with everything off to be safe the abs and some other light came on momentarily. i almost made it home the cluster started to dim out so i kept the revs up a little bit and managed to make it home as soon as i got home i turned the car off and checked if it would start and again it lost all electrics I tried running a different earth and checked that the fuses and relays had good earth all seems to be okay with my test light. unfortunately broke my multimeter the other day though :/ the embarrassing thing is im a Nissan technician and have no idea where to start. there's no manuals or anything relating to imports at work :/ has anyone had a similar problem with there r34?? or maybe have a good lead for me to start chasing? pretty frustrated and flustered with it Cheers guys :happy:

It does sound like an earthing problem. Could be one of the internal earths or in the engine bay - they won't often show up with a multimeter - they'll only show up a fault with load on. Maybe systematically check all of the main earths (in the engine bay) and try some of the internal ones as well.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
