not sure the maf would cause it not to start, one time when I was working on my nissan maxima, 1998 , I forgot to hook the maf back up after installing a starter (yea its buried) anyway, it started and idled fine, but anything over 1000 rpms made the car run like crap, so much that it would actually slow down, popped the plug back in the maf and off i went.

not sure if the maf is similar for the kia in relation to it not starting
