i have no tac the key light and check engine light is on and cant connect to obd2 port and it runs very rich help

 

Sounds like Your ECU might be having issues. Does it give an error when you try to read it or does it just show nothing?

 

i wont connect at all hears wat happened i was going down the road the battery light came on then that happend and i cant go over 20 mpg and my temp dont work

 

The battery light indicates a charging system problem. If the alternator isn't putting out enough voltage it can make the ECM/PCM act weird or ruin it. First thing to do is to test to see if the alternator is bad.

 

the alternator is ok its charging the battery iv checked everything all the fuses

 

How, specifically, was the alternator checked? Just because it's charging the battery doesn't mean it's working right.

Download the manual and diagnose for a bad ECM/PCM if the alternator is ok.

EDIT: Are all your grounds good?

 

i got it checked at kia and my grounds are good and were do i get the manual
