ok put a new engine in my skyline rb20gts-t. started it... started ok for couple of days. then last two days when its cold it starts fine cranks over and runs on idle fine then i turn it off after 30min....go to put car in garage it wont start. cranks fine but no start..i have put new spark plugs, coil packs. the car is getting fuel so not fuel problem. changed computer so not computer. took oil cooler off cause i thought i could have connected it wrong. still same.. so what do you guys think? please help. could it be crank sensor? but if it was it wouldn't have started right?

cheers

only starts when cold? sounds like my old car

Get the injectors cleaned out, it's not spraying enough fuel on start up hence the car isn't starting, when the car is warm, there is no fuel compensation.

Also, is your PCV plumped back into your cam covers and intake? having an atmospheric catch can setup and the PCV still installed will also cause problems when there's no positive pressure in the plenum.

yes only starts when its cold. and when it starts i run for 20-30 min switch it off. then i cant start it again. just cranks over.

i dought the injectors will need a clean, the car does start only when cold though, but i will check with mechanic about injectors, edit: with injectors they are pumping petrol as i can smell it heaps when it cranks.

whats a pcv?and i dont have a catch can,

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
