Hi Guys,

My car seems to have a problem whereby if i am say going around a round about, i cannot give it any real power otherwise the car literally starts to conk out and almost stall/come to a crawl unless i back off and when im out of the corner a bit it will let me put the power down again. Its a bit freaky to be honest... like im out of petrol. But i had 1/3 of a tank the other day when it last happened so yeah thats not it.

Anyone had this problem before and know what the cause is?

fuel starvation at the pump end,

Your fuel pump has possible fallen out of the cradle or you micht have some crap stuck on it.

VERY bad for your engine. because it will lean out and go BANG!!!

Drive very carefully untill the tank is bone dry and inspect the fuel tank.

yes it's either:

1. your aftermarket pump was not mounted properly (not low enough and with a good pick-up)

2. your pump is dying.

3. your standard pump has come out of the cradle, or the cradle has slid out of it's bracket at the bottom of the tank.

either way get into the tank and see what the problem is. it will be killing your pump very quickly if it's running dry like that so often.

It only happens if i try to put my foot down in a round about or sharp corner, normal driving it almost never occurs, so i know how to avoid it.

I have stock fuel pump with a GTR fuel filter.

I dont think this is something i can do myself because i have absoltely no idea how or how anything should be. But are you saying the tank has to be empty??

tank doesn't have to be empty, but the less fuel, they nicer it is to do. if you are not sure what you're doing just take it to a workshop. any competent mechanic should be able to sort it out no problem.

ok so I'm having the same problem however 

I have walbro 341 pump it is getting pretty old was in the car before I bought it, brand new Link ECU and boost controller. and other mods.

not sure if how much psi I am running is relevant but gate pressure is about 13-14psi. stage one is 17 stage two is 19.5. 

under load when cornering fuel cut occurs. happens up some steep hills if I put my foot down to much. does not happen under braking. 

along a straight roads at slow speeds sharp left to right it also cuts out..?? 

any ideas?? my thoughts were possibly a sensors is not happy there for telling the ECU to cut fuel?? or typical pump mounting or pump is on its way out..

Is your Walbro directly wired? Get your fuel pressure tested (have you replaced the fuel filter in the engine bay?). Have a look in the tank to see if pickup is still in the right place and sock on the end is in good nick.

I would just pull the access cover in the trunk/boot and pull the whole fuel cage and see what the deal is...with the cover off can shine a light in and see if there's any sediment too

Kiwi curious where the fuel filter is? just got a gts4 with rb20 and probably wouldn't hurt to do this to mine

Assuming its the same as my Stagea (might not be) just follow the fuel lines back from the rail to the side of the engine bay and you should (might) see a disposable filter clipped to the  side. Actually here is a thread with some pics as well as a "how to " link -apparently they are a pain to do on your car:

      Cleaning my wheels 😍

      By Milkmun · Posted

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.

      Probably a smart choice to buy one vs build, purely for the motivation part as you said! Imagine the metal dust everywhere from grinding all the steel to build one. Ha ha ha!   Also, post a photo of your garage.   Mine is below, this is where I've been cleaning and have already half filled a caged 6*4 trailer. And this is after my cleaning expedition mentioned previously... The middle normally has a car in it, but I'm dumping things in the middle as I sort through them. And poor skyline was dusty and has had the lightest few drops of rain and now it looks atrocious and needs to be dragged back out and washed thoroughly! And yes to the right is technically another bay, you really can only see 2 bays out of 3 in this picture.

      It's more like on average the things I see a lot of things going wrong. Yes, usually the people who reach out are the ones who are having problems but on average it feels like mechanics and tuners here aren't really competent. I swing between thinking my standards are just way too high and wondering whether people really are just this dumb. I just had the strangest 10+ reply argument on a Facebook group over someone insisting that the factory R34 GTT boost control solenoid reduces boost pressure to 5 psi when it's on and raises boost pressure to 7 psi when it's off despite showing the exact plumbing in the factory service manual and the solenoid behavior detailed in the FSM.
