Rod is correct...any engine needs fire, fuel, air, and compression..I always start with fire, if you have it then move on to fuel...95% of the time the problem will lay in those two. Once you figure out what it isn't getting, then work on why. Newer cars have a lot of computorized stuff that require specialized equipment and knowledge.

What sensors have been replaced? There are several sensors that can cause a modern engine to not start. Have you checked for current diagnostic codes? Have you determined that if you are getting fuel pressure, spark to the spark plugs, and injector pulse to the fuel injectors?

    For an engine to start there has to be the proper air/fuel mixture in the combustion chamber, compression, and spark that is at the correct time. The CMP and CKP sensors, if installed correctly and working, should ensure the spark happens at the correct time. But you didn't mention if you confirmed there is spark. You seem confident fuel is getting to the cylinders so the only things left are to confirm you are getting spark and that the cylinders are building appropriate compression.

    spark and the cylinders are building appropriate compression but it still won't start

    Well, one of the items listed above is not correct. If the fuel is good, the correct amount of fuel and air is getting to the cylinders, compression is correct and rather uniform across all cylinders, and the spark is strong and timing is correct, the engine will start. You may need to recheck all of these items to determine which one is not happening correctly.

    Thanks guys it was the timing that was incorrect got it right and the car started. Big ups to your valuable input

    I think crank sensors are actually the problem because the care needs to be easy before starting and crank sensors slows down the car and sucks the engine of the car. I recommend you to read article and learn how to take crank sensors because the car works perfect without it.

SOURCE: I am changing the spark plugs on my 2004 Kia sorento

Be careful there.. If you remove the Throttle Position Sensor TPS or the throttle Cable, the engine light will come on because there is a certain setting that needs to be done to ensure accurate emission control.
