Ok so I had the ecu out just to see whether it was a completely stock ecu or remapped etc, and when i plugged it in again, they car started and ran for about 1 minute then died and hasn't started since, when I turn the ignition on the check engine light stays on and won't go out like it should do. When i put the ecu into diagnostic mode it flashes code 55 meaning everything should be fine? but still the car won't start. I can not smell any fuel in the exhaust after cranking, but can hear the fuel pump prime when i turn ignition on... so maybe something to do with the injectors? or could it be the airflow meter? the ecu has a bit of dodgy wiring behind it where something has been tapped into it in the past but everything looks like it's connected to where it should be so I don't know whats causing the problem? Any ideas guys...?

If I wrere you I would firstly only look at the things you touched and not jump to other conclusions yet - why not pull out the ecu again and make sure all pins/connectors are OK - re-connect evrything and try a start again - no doubt others will offer suggestions also

funkymonkey - yeah starter motor was working, engine was definately cranking over.

lachlan33 - yeah there was a wire that has a joiner in it that came apart but like i mentioned earlier in the thread i'd already checked all the connections.

Problem was th blown fuse, not sure how or why it blew but guess it was just doing it's job, starting fine now.

Thanks guys

    • 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)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
