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
