Basicly every now and then our car decides it's not going to start and it just cranks n cranks n cranks and we always end up having to clutch start it. And when the car does start it will blow alot of fuel smoke, coughs and splutters, fuel smoke dies off after about 5 seconds.

Thing is this happens if its wet, dry, if the engine is cold, hot, if it's been driven normally, or if u give it a little boot, small trips, long trips, its ultra random.

We have so far tried a couple of things. We unplugged the injectors and the car turned over and ran untill it ran out of fuel. We had our injectors checked and cleaned about 4 months ago, flowed fine, no drips.

We got a new battery so it's not that...and we have it serviced reguarly.

Basicly wondering if anyone has any ideas on what could be causing this problem?

hi there socko you will need to check the fuel pressure regulator to see if diapham has a hole in it which causes the fuel pressure in the rail to bleed back into the mainifold and flood the engine when you try to start it . the easiest way to do this is to pull off the vacuum line that goes to the pressure reg and see if it has fuel in it Try that first and let me know thanks mate

Ok that's worth checking n I will get Adrian to check that when he gets home from work. Because it is getting to much fuel when it's doing it...But wouldn't that cause it to do it all the time? The car only does it randomly...Altho it is starting to do it more often...

My rb25 does exactly the same thing but all the time. Its rare that it starts straight away. Receipts i got with the car show like 4 new batteries so thats not it. Always starts eventually but cranks for like a good 10secs. Checked the FPR hose and is dry but that was bout 15mins after turning off the car. Should i check when turning on the car or will it make no difference? Any help appreciated

We went to a guy yesterday and he plugged our car up to the computer and it ended up being the water temp sensor.

Basicly the water temp sensor was sending the cars computer the wrong singal which lead to it thinking it was cold all the time. So off course it kept putting more fuel into the engine than it needed and it was flooding it's self. Which explains the problem starting it and the problem while driving it.

So it's all good now :)

      Looking for a part number for this part here

      By eli995 · Posted

      (Rb25det intake manifold) I’m having a hell of a time trying to find the full part or part number of this coolant hardline so far I was given these (Below) but they aren’t what I’m looking for and was told it’s the IAR or aac valve but that doesn’t seem to be it either. If someone could point me in the right direction it’d be greatly appreciated. Or if anyone has it for sale that’d be great too. I have recently purchased a greddy manifold and I can’t seem to find my old one to pull it off.  (Front Heater Return / Water Pipe (under intake): Primary part: 14053‑21U10 (front return pipe assembly for R33/R34 RB25DET) Alternative listing: 14053‑21U00 (same pipe, sometimes interchangeably referenced)   Heater Feed Pipe: Listed as 14075‑04U00 or feed-related variant 14053‑AG500)

      This sounds cool. But, as per usual, anything really complicated like that, that I take on, constitutes a steep learning curve that I never actually "learn". I just get it working, install it and start using it. Then, when it breaks a few months later, I've got no memory of what I did, how I did it, or even the bloody IP address I gave it. I'm having more or less exactly that problem right now. My Proxmox machine was discovered to be non-responsive, and the VMs on it were ditto. Power cycle it to a stream of loud Dell beep codes - which was unpopular at midnight, I can tell you. Move it to the lounge room so I can HDMI it to the TV for a screen, see the boot messages complaining about the /PVE/data having all sorts of LVM problems, saying it needs to be fixed manually. And I'm like....great. How am I going to work out what I need to do? At least it wasn't the stupid Silicon Power SSD shat itself. Mental note for all readers - DO NOT BUY SP SSDS! They are shit. I have had one take out an entire VM setup already, and this one could have done the same. Maybe it actually has. Cheap Chinesium shitbaskets. I won't cheap out again, even on play projects with no budget. Because my time budget having to fix shit is worth far more than the cost of proper parts.

      I do typically agree. These days even the screens most people use have more of a boot time than the main device. However, I've seen an interesting use of the RPi in vehicle, however it involves effectively building your own OS and MBR, as then it boots up exceptionally quickly, as you don't have everything needing to start up, and you can then also run it up as an RTOS, while still having more compute than an Android can give for things like display, and processing. A very huge task that would be though for Duncan, I'm not sure that's his skill set (or Arduino programming and wiring) ha ha. If end goal is definitely just water cooling, Arduino would be the simpler setup especially for a rookie. If he wants extra display stuff though, bashing some code in Python on an RPi may be the better result for both systems.   Unfortunately the new device I'm building at work which runs a display, is too slow of a display for dashboard style purposes. More extreme low power, update only a couple of times a day type system

      I don't like "actual computers" for in car use. They take time to boot up, have OS annoyances, and so on. Arduinos etc are ready to go a few seconds after power on, don't mind being agressively powere cycled, because everything is non-volatile, don't mind being shaken and stirred.

      As Fred would tell us, it's all about interpreting the rules. It's not a water sprayer, it's a water mister... But everything else you've said, 100%! Even a raspberry Pi would be great, use HDMI out for a display, and add a raspberry Pi CANBus hat to read values out from the ECU.
