OK, im sure heaps of people have posted the same sort of questions im about to ask, but just bare with me. Ive skimmed through other threads, but they havent really coverd my problem. I just got my gtr 32 three weeks ago. Got it home, and i was sure the fuel pump shit itself, because it didnt seem like it was getting fuel. So before changing the pump, i changed the filter, cleaned the tank out and little things like that. Didnt fix the problem so i bought a walbro pump and put it in. It fixed the problem to a certain extent, but it still seems like it doesnt get regular fuel. Problems i think it could be... Stuffed fuel pressure regulator... Stuffed afc's. Also ive been told that maybe the 02 censors could be dirty???? doesnt sound right to me. It sometimes doesnt get past 2600rpm. which i was reading that usualy is your afc's? But mainly it drives good then cuts out and when i start it after a drive it strugles to keep idle. Other times it drives like a dream. This is my first nissan and i wouldnt have a clue where to start. So it would be absolutely great if you guys could just help me! i really need this. Its killing me having my dream car in my shed not being driven. :)

Thanks.

Check:

All vacuum and boost lines,

Sensors and their connectors.

My Dad has a VL Commodore and the AFM was loose so maost of the time it ran good and occasionally ran like a pig. When I first got my car, one of the knock sensors was loose so it was going into safe mode half the time. I also found that my boost gauge was not working due to the vacuum line off the back of the inlet manifold being cracked. By replacing the hose I now had no vacuum/boost leak and my guage now works. When I fixed the knock sensor the car runs like a dream.

So just look at connections to all sensors and listen out for those leaks.

Good Luck :headspin:

Try getting the injectors cleaned but I think your problem might be more Air flow related.

It is very unlikely that it will be a regulator problem but don't rule it out. I think I have replaced like 1 reg to a hundred pumps.

yeah, its my airflow metre, well the top one. I hooked some kind of absolutely cool device in. its a hand controller for the computer, i plugged that in and it told me straight away that there was no response from airflow 2. which happens to be the top one. Still trying to figure out wether its the wiring or the airflow metre itself. I guess now im on the look out for a gtr airflow metre. Just standard, no point in upgrading if they are just coming out in 6 months time anyway..

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
