Car has problems starting sometimes - 1993 240SX

Alright so sometimes the car will have problems starting.It will crank but not start, and it will randomly sputter. If I gas it sometimes it will start better, sometimes not

My guess is i'm not getting proper spark, but after it starts Its fine, no idle problems, no acceleration problems

What else could it be?

Fuel system problems or air intake leaks.

Well fuel is fine, i just replaced fuel filter and pump, and can hear the pump, unless its an injector, but i doubt since when it starts my enigne pretty much was flooded (Black smoke for a few seconds)

Well your methods are quite thorough but how do you know every cylinder was flooded and not just 3 or even 2.

When do you experience the starting problems?

I use to have a similar problem don't know what it is still , But it would mostly happen in the cold and for some reason my radiator went out and when i replaced it i didn't have a problem anymore well so often
