help help

I have a 96 Kia sportage 2.0 DOHC..

is hard to start.. it turns over and it wont crank, i have to have my pedal all the way to the floor in order to crank.. is getting too much fuel because i replace my plugs and they were BLACK.. ones it cranks it feels ok..
like two weeks ago it did it once but then it quit doing it.. until yesterday... i replace my fuel filter and i check the pressure before my fuel filter and is 58 psi.. I also replaced one of my coils. because when it did it the first time the check engine light came on and it said that my 2 and 3 cylinders misfire.. and then another code saying RANDOM misfire.. i don't know what to do.. can somebody help me..

thanks

Sounds to me like your timing is off. Maybe time for new timing belt and valve adjustment? Just my opinion.

My timing is ok.. so far i checked..

Fuel pressure 42 at idle and 38 psi whe cranking
NEW TPS sensor
Cleaned IAC
Fuel pressure regulator WORKING
Disconected O2 Sensors
Catalyc converter are GOOD
Good Battery and starter..

cold in the morning it cranks ok but after a few minutes it will not cranks unless you move the pedal somtimes a little and sometimes all the way..

i'm running out of ideas...

thanks
