Appreciate the direct "Ask Me".
Hard starting could be caused by a number of faults such as weak battery corroded/loose battery terminals, fuel delivery issues and others which may include as you posted the MAF sensor. In my country however, most Kias have a peculiarity. They like to be well warmed up (even if it is hot here). Hard starting specially after short hops/trips is actually the ECU/ECM/Control Module or the car's computer getting mixed sensory inputs. The corrective action is to warm up the car fully before using. In some instances, it may also be required to reset the computer by removing the negative battery terminal for a few minutes. Pls bear in mind that some alarms are triggered this way and/or some car stereos would require a security code if the battery is removed.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

I had a simaler problem in my 2002 sedona. try replacing the EXT fuse in the engine compartmentand check the rear hatch light inside. Mine kept blowing this fuse because this light bulb was bad.

yes the crankshaft position sensor can cause all these problems at once. they are fairly simple to change and not a really expensive part if you want to check it though you can unplug it and hook a multimeter to it and check ohms as someone cranks the engine. should see a square wave as in 0 ohs to infinity ohms and repeat.

Try replacing the bulbs. If that doesn't work, check the fuse and replace if necessary. If that doesn't work find the relay and replace it. If that doesn't help, then you have a break in the electrical system somewhere.
