Dear all,

So... I just faced an issue with my BNR32. I was leaving the carpark (cold start), but i stalled (don't ask why), so the car rolled back down.

THEN, i put it to neutral, and tried starting the car. BUT the car did not start. It was a "crank but no start" situation. 

I tried a couple of times, but just will not start. I googled, and came across an article about fuel pump, fuel injectors issue, etc.

THEN, i just tried my luck by cranking the car at 2nd Gear. Miraculously, the engine ignited. 

NOW, my question is WHY it happened? and WHAT to fix?

Stock ECU and stock injectors?

If so I'll start with cleaning your AFM, and injectors. If they're clogged or gummed up, it will be a bit too lean to start. If you're in this situation, unplug your coolant temp sensor (2x pin one not the 1x pin one) and it should start.

If not stock ECU, tuned and worked etc. then could be a poor cranking table or coolant/IAT/fuel correction table issue or clogged injectors or anything really.

Hey! thank you!

I was able to start the engine normal prior to stalling. But after the stall, the car cannot be ignited but cranks (both at 1st gear and neutral).

After a while, the car was able to ignite at second gear. Today, the car starts up normally and even though i stalled it on purpose, the car is working normally.

Is it something that happens normally? What exactly is the issue?

Gear position / neutral has nothing to do with it. You have just experienced something weird. As my crystal ball is currently out getting resurfaced, I am unable to discern what caused it. Please call another psychic.

HAHA thank you. Didn't really understand what went wrong. Thought might get some answers from here!

Thank you all! Just an update and maybe someone could explain to me why so:

SO, i tried stalling the car the same way i did before. Again, the car could not be ignited. But this time round, i tapped the throttle whilst cranking the car and it worked.

My guess is that there isn't enough fuel injected when the car was climbing the slope of the carpark - causing it difficulty to start the engine (?).

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
