hey ok here goes ill try explain best i can what problem im getting

sunday just gone i was driving along and my fuel pump died and car stalled

so i order a new walbro intank pump, i got the pump yesterday and we attempted at installing it

which i thought we done a alrite job, we wired in a new relay aswell with new wiring, but what was

strange was before we started wiring the pump in, we could not get power to the 2 pin plug at ALL which

left me and my mate stuffed, then 15mins later havnt done anything we get power, then 5mins later no

power again and again and again, we had no idea what was happening, anyway we thought stuff it and

put it all back together and started wiring in the new relay, we run a power wire straight from the battery > relay,a

earth from relay straight to the battery,a earth to relay then earth 2 chassis from the pump and a power wire to the relay from the

pump, now the pump flows constantly while car is running, just before driving home from work, car decided

to stall 3 times just conk out instantly,i pulled over the side of the road and tried crankin the car over and

over but it wouldnt start,the pump was priming,eventually after about 10 x at kicking it over it started and i

noticed that the pump DID not prime the time it started, wat im wanting to know is, is the stock fuel

regulator having a heart attack with a constant flow of fuel? im scared 2 drive the car incase i stall at set of

lights and spend next 5mins trying to get it to start again :( also the way we wired up the relay does this

sound right to you all? who have exp putting a new pump in. hope u guys can help me out cheers

Justin

the fuel regulator will be fine with the flow, it will just return any unused fuel back to the pump return line. have you checked for other obvious causes of stalling (it might not be the pump). stock ecu diag would help. also check airflow meter and plug

do i just turn on the car and kick it over and take the ecu outta kick panel will it have lights if its showing any errors? ive just recently cleaned the idle valve thing on back of plenum like it says in the DIY section, fixed my idle but now im worried about the car just dieing in the middle of driving :(

Sure you put the hoses etc back on properly? Could be a leak in there. Double check everything you touched first. Then check the AFM is plugged in (although the ECU diag will tell you that).

yep i checked all hoses and there all on there fine, i cannot hear a vacum leak at all, when car is idling fuel regulator is screaming! because fuel pump is pushing constant fuel to it, swear this cant be good? should i upgrade the fuel reg? maybe the reg is over working itself then shutting down therefor stallin the car, then when i prime it more it finally kicks over?

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to it's full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so damn hot in there, that made it all the more easy to remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. I was standing there looking at the car and said 'f**k it'. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      R33 GTR running -9 with no tune

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
