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:

Awesome thanks kiwi...looks like I'll get it changed out this weekend

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.

      Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.

      @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.

      Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
