Engine Starts And Cant Start Again..

[Curmi]

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

car has bosch fuel pump, gt2876rturbo, full exhaust, pod filter, stock computer, fmic, if you need that info.

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,

there's your problem right there..

take your injectors out (might as well clean them) and whack new injector seals in.

when your car is hot, disconnect the AFM and it should start
