help! KA24de wont start at first startup of day!!

[haxoraxe]

I know there is a lot of threads telling ka24 wont start but ive searched and none resolved my problem.. See, I know the maf is dirty and my filter is not good but i think that's not that problem, since when i push start it, it will idle perfectly... and after that it will turn on after like 3 trys but not at first one... it seems it happens each time the engine gets cold... ive checked ecu and it threw me 55 so idk what to do... its been like that for about 2 weeks, even when i changed injector yesterday the problem still was there...

help plz
