pull out your spark plugs again and inspect them. that will give you an indication of whether it is a fuel issue. if they are black then it isn't a fuel issue but a spark issue. if they are a light colour then it is a fuel issue. if possible get someone to drive behind you and make it play up. if they see unburnt fuel coming out the exhaust when it missfires then you know it's a spark issue.

legend. will do

how much boost you running?

i have a similar issue and i thought its just the stock ECU fuel cut or R&R, if i reset the ECU it will be fine for a while....

how long was a while.. what did the final problem turn out to be?

generally if the fuel pump is playing up it will usually only be in the high end where it starts to lean out. generally it should be fine at lower rpm as the fuel being used is very low so the pump should be able to flow well enough.

wouldn't hurt to replace it to be on the safe side, however if it isn't the issue then you have wasted a few hundred dollars. you would be best off putting the car on a dyno to get the AFR's checked to see if it is leaning out. that way if the AFR's are fine you can put the money towards finding out exactly what is the cause.

First time Ive had a drama with the car is today :laugh:.

Turns out mines doing same thing, But it does it at anything about 0+. shuders, hesitates, splutters, as if a cooler pipe has gone off :S

all new Gear, intake, gaskets, splitfires, tomei z32, about 80 dyno runs, never had an issue. today started it, driving to work.. this happening >.<...

I have no idea bro, sorry. Man, I'm sending the car to a dude in Melbourne that comes highly recommended. Supposed to go today but had a wedding I sorta forgot I had to go to. I'll go to him early on Monday. If he tells me the cars problem, I'll pass that on to you, or if you're in Melb. tell me and I'll give u his details.

the dude fixed it in 15 seconds. f'ing very good guy.

#1, the turbo we changed was boosting (or trying to at least) at 22psi,

#2, the afm was dodge so i replaced with the another standard one,

#3, the loom that sat in the afm was pretty shockingly crusty, so we changed that and he crimped it into place,

#4, the bov i had on the car was pushing a lot of what was in the pipes out, so the sensors got crappy readings and made it try and cut out,

just little bits and pieces. the dude did a massively good job, anybody in melb who wants serious work done to their car should go there.

i hope some of these steps help u in ur problem cuz.

good luck.

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
