L have a 2003 Kia Sorento, sometimes it will just turn over but won,t crank. after a while it will start up. or l can be driving down the road and it will start poping and cut off, and won,t start.it does this a lot. only sometime do l get a code (crank position sensor.)but sometimes when it acts up l won,t get any codes. could this be a computer problem or crank shaft position sensor.

This is almost for sure the fuel relay. I do not know where it is on your car but I would look for it to be by one of the back wheels where road junk can get to it and corrode it. Once found not very expensive and very easy to replace.
