Didnt wana short anything or create a fire lol, so do u think the black/yellow wires are the ground wires - theres three of them goin to one. I tried to call you a few times today. If you comin down to Syd tomorrow to do Sir RBs rewire, I can come see you, if the roads are dry and you are free, then I would like to get it road tuned as well or otherwise Easter??

Oh and my no. is 0416424446, I think it is set to private

cheers

I havent planned with Michael yet. I still havent hadthe balls to ask my fiance yet lol.

U should both drive to my place and ill do it all :) u can cruise up here together.

Ok cut the yellow/black wire. Then disconnect pin 86 from the relay end. Cut the terminal off this wire. Connect this earth wire to the yellow/black wire coming from the pump.

Then the other yellow/black wire that joins to 3 or what ever u said it does needs a terminal on it and connect to pin 86.

Try this

thanks man, going to try this now, did u forget to mention that I need to cut the green/white wire goin to pump and connect the pump end to pin 87 and the ecu end to pin 85? Will do that I think. Please text me ur address

cheers

All went well. Fixed up the wiring to the fuel pump. Road tuned the AFRs.

Needs a turbo to manifold gasket a decent dump pipe an a highflow cat then we will see how it goes on the dyno.

R34 gtt fuel pump wiring is

Green white from pump to chassis earth. 

Green white from ecu to pin 86 earth

Black yellow from ecu to 85 positive trigger

Black yellow from fuel pump to pin 87. 

Pin 30 battery 12volt supply

Thank u Jez, the tune went great, its running smooth as ever, as you mentioned, need a 3" hiflow cat, turbo-manifold gasket, (dump pipe maybe later) and a re-tune on the dyno for power figures, ign timing maps, more boost, knocking and tuning 4th and 5th gear tuning. And I gotta fix that fuel tank seal as well. So many things to do, need to get it out of my head asap.

I recommend Jez AA++. If any of you thinking of getting a tune(Nistune, Power FC, Haltech) or any electrical / mechanical work, he is one top bloke, DVS Tuning located at Central Coast. Check him out, he was awesome to deal with, +1.

Thanks again mate, you did a great job.

Mine R34 gtt is having the same issue as rondofg all the wirings fkn hacked to bit I followed your wiring above but I'm having a issue as I'm. Trying to wire up a solid state relay instead as I'm running the walbro hellcat 525 and it was melting 40amp relays

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
