Car will not start after engine is hot .Will not even turn over.

If the car is running hot, it probably has a sensor that shuts the car down. It is designed to keep you from damaging your engine if It gets too hot. It will not let you crank it until the car has cooled off sufficiently. Find out what's causing the car to overheat. If it's not overheating, you may just have a bad temperature sensor. It will probably be on the radiator. Please do not remove this sensor if your vehicle is overheating. Your car will only drive a short distance before catastrophic damage occurs, and you'll be out a few thousand dollars to replace it.

Might be an engine coolant temperature sensor going bad.

crank sensor failing i'm thinking does the engine start when its cold then cut out when its hot say 20min or under.

Sounds very much like your fuel pump is done for. After it runs for a bit it starts to get hot & quiets working once it cooled down it started working again. This is very common but more frequent if fuel in tank is low. It realy will take a fuel system test to verify.

My mom has a 2013 Kia Rio Car starts up fine but while you’re driving at a nowhere the car starts up fine but while you’re driving The car will Shut off but all the power still on when you turn the car completely off and wait for a little bit turn it back on the car will start but the RPM gauge won’t work you have to turn the car off again wait for a little bit start Pumping on the Excelerator while turning on the car in the RPM gauge works then it shows a check engine light but the car works fine After you park the car for a few hours turn the car back on the check engine light is off can anybody help me with this problem

try to clean the fuse box and keep it dry from humidity

You need a motor. If it overheated and stalled as a result than you cooked the engine.

This sounds like a "heat soak"issue(something is failing on a hot engine shutoff).The low tech solution I used to use often was a can of brake cleaner.Get the car hot,shut it off,and try to restart.If it wont,try spraying a quick burst of cleaner at various sensors(to cool them off) and trying to start it again.The most common sensor I would find as the cause was the crankshaft position sensor.(Sometimes a little tough to get at).

check for a bad fuel pump relay. it maybe geting hot and shutting down. it may be a bad coolant tempurature sensor also, that sends info to ecm.The engine will think it was still cold, even though it was not, causing all kinds of things to run draggy. thats why it runs ok when its cold. it sends wrong info to computer. thinking its cold, when in reality its warm. have a good day !!

Seems to me it's the engine coolant temperature sensor or the connecting wire to it. Some Model/Year (MY) hyundai's have TWO (2) temperature sensors.. one for the instrument panel/gauge, the other strictly used by the ECU (Engine Control Unit)... if this sensor goes bad, it sends the wrong data/signal to the ECU and this can affect engine performance.
