Question about 2004 Kia Rio
I have had to replace the mass air flow sensor twice already. It will not start. It sounds pretty bad when I tried to re-start it. Is there supposed to be a belt at the fan near the radiator? Yes dumb female here ha ha!!! Could it be the fuel pump shut off because I hit the dip too hard? There is not a belt at the fan by the way but it looks like there should be since it looks like there is a pulley there. All the fluids are fine. I am hoping it isn't the timing belt since everyone says that probably means I no longer have a car.
Yes there is a serpentine belt that runs the alternator and accessories. That must be on the engine.
Unless you damaged the crankshaft or the oil pan I doubt hitting a bump or dip would do anything to the timing belt. It is behind the cover behind the pulleys. But anything is possible.
You could have knocked a wiring harness connector or other component loose.

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.

The mass air flow meter is fitted to the air intake pipe Its quite a simple task to change it on your own.Has for the catalytic converter all you will have to do is give the car a realy hard reving when going through the gears and drive it hard for a few miles.That will clear your cat for you.Dont listen to the shop they are out to rip you off.Good luck.Any problems you can contact me via firstname.lastname@example.org.

SOURCE: mass air flow sensor is
My check engine light came on and the code came back saying that the mass air flow sensor was out. All I did was change the air filter even though I really didn't think it needed it, the light went off and has not come back on yet. Knock on wood!

did you use aftermarket crank sensor? if so that might be your problem. dealer has several different ones, by providing vin number, but there is only one after market for all optimas 01-05. try to connect thick pink wire and thick orange wire together on the ignition failure sensor. you might have the same problem as me. good luck.

p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.
