just replying to cam r u running an aftermarket bov and an air flow meter or a map sensor i know that some nissans run a system that when engine rpm is below 2000rpm the fuel pump circuit switches voltage from 12v back to 9vdue to fuel pumps being too noisey toyota soarers run this system as well have u set base idle and iac learnt where base idle is car looks great

maybe some help with nissans stalling are most of the cars have standard ecu and aftermarket bovs because when bovs fitted the bov stays open @ idle because of the manifold vaccum which in turn bypasses the airflowmeter and run exceessivly lean so when u up the fuel preassure may temp fix the problem to check to see if problem fixed put a 1 way chek valve on the vaccum side of bov e.g xf falcons have a 1 way valve on the carby version its green and black this stops the bov openning @ idle or when pulling up to lights and still when on boost holds the bov shut and when gears changed only lets of excess preassure and not too much boost which in return slows turbo lag. just trying to help a few nissan owners

cheers.

I just recently purchased a 1995 Series II R33 and it appears to have a stalling problem aswell.

The spedo first started to just drop out down to 0 and would come back if i gave it a bit of a tap. it still does it now. I had a 3point alarm system installed, and not long after getting it back the car began to stall. it doesnt just stall at a low rpm but usually does around 400rpm. I could be driving and the power will just cut out. not just when i am approaching a stop point.

Im not sure if it could be something that happened when they installed the alarm system or if it could be something relating to the spedo and the wiring in the dash with its gauges, just looking at some of the other posts it makes me think it could be something else.

any suggestions would be greatly appreciated.

I would like to share my own stalling experience.

I have a r32 gtst auto (full 3inch system is the only mod), my car use to stall when coming to a stop, going around corners, and at times when cruising at around 3 grand bunny hop. Occasionally it would cut out even when i wasn't coming to a stop.

The solution to my problem was really quite simple. Clean the airflow meter.

So i took off the airflow meter and gave the sensor a good clean with electrical contact cleaner (available at Tandy dick smith etc). Now, no more stalling issues.

I can tell you the most important thing all the nissan people out there, the connector/s to airflow meter is the most crital connection in the entire engine managment and it is the cause of most problems in nissans of any breed. After all the MAF is used in practically all fuel based mathematical calculations within the ecu. If you have any problems with you car running shit go and check the connetor to the MAF. I guaranty it will fix most problems

hey guys. i have a r32 GTR and i started to stall the other night =( the revs kept dropping and it wanted to stall it was ok for abit i took it for a spin around the block and it stalled on me i took it back home and left it running for awhile and it kept stalling and stalling and stalling. so i turned it back on and hit the throttle afew times to about 4000rpm then let go i got alot of black smoke coming and it back fired like a mother =(. think this could be just a fuel pump prob? black smoke? back fire? anyway could someone give me more detail instructions as to how to ground this earth fire on the fuel pump? like a picture diagram ^_^ thanx

Sounds like it is running extremely rich, for what reason I dont know though.

I think everyone should check out there CRANK ANGLE SENSOR - Coil Packs - & for series one rb25det's , they should check out the signals coming out of the Ignitor pack, that sits above coil pack #6

like anyone is going to listen to you in this community mate u screw people

f#ck off

mmm my 33 does it, infact did it twice today.... only mods i got are pod and bleed valve...... scared the shit out of me coz i was coming to an intersection and i slowed to take the corner, car stalled but i didnt realise for some f**ked up reason lol coz i still had lots of momentum, but i lost power steering while i was half way through the corner and allmost hit a car coming the other way :s

threw it back into second and took foot off the clutch and it roll started and was all good again, but it scared the $hit out of me

Might be a TPS error if the MAF sensor has been checked and believed to be working. Calibrate the TPS so that it is 0% with the throttle shut. Take note you will probly need a Nissan Consult to perform this proceedure. This should kick in the IAC valve when the throttle is shut, ie when coming to a stop. Let us know how you go.

mine was starting to do that quite a bit.. going from higher speeds to low speed turns, revs would dip, then jump up. Sometimes they wouldn't jump up enoigh and it would stall. Changed AFM over the weekend.. problem fixed. The other one was dirty I'd imagine.

it is weird how all nissan owners come across this somehow

got the problem in my 180 at the moment - car is in shop and let mech know so hoping he can find it

the usual checklist to go over is as follows:

* check all your vacuum lines for leaks

* check bov isnt leaking

* check AFM

* check o2 sensor

* check TPS

* check IACV

* check fuel pressure (which is wat this re-grounding the fuel pump earth whoo haa is...)

* check ecu pin outs and connections

* check not running excessively lean or rich

that seems to be all the usual suspects and if you check all of them thoroughly you SHOULD fine the problem

could somebody please tell me which wire needs to be cut and re earthed. i cut the black wire that comes from the pump and re earthed it. it didnt do much, but my fuel gauge reads empty. so im guessing thats not the right wire. how can i find out witch wire is meant for grounding??

  • 2 weeks later...

I have an R32. I believe that the ground is the top-right wire when looking at the pump-side clip. It is a white wire which is thicker than the others. I think the others are as in this diagram

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
