Hello.
Helping a friend. 2013 Aveo fires and work fine until turned off.
It will crank but not turn on when hot.
I'm traveling, so if you know of any part/sensor that could cause that problem, please let me know. Replaced CPS, no help.
Again, it will start and run fine if started with a cold engine it can run fine all day long, until turned off.
Sounds like vapor lock to me.
Try spraying a very small amount of sensor-safe starter fluid into the intake to see if it will fire on that.
Thank you guys. Will try.
I was thinking maybe a sensor.
Trouble is , there are LOTS of sensors .
God bless

Yes, many sensors but not that many that may cause that problem.
Thank you anyway.

Taking a stab in the dark , I would guess something in the ignition system getting problematic when it gets hot ? Coil pack ?
I suppose you might have a heat related problem with a crankshaft or camshaft position sensor ?
Does the fuel system have a Schrader valve , so you can easily connect a fuel pressure gauge ? Would be helpful to know what the fuel pressure is cold , then hot .
My understanding is , just about all the vehicle with electronic fuel injection have the pump in the tank . Pushing the fuel .
I think of vapor lock more with older vehicles with carburetors and mechanical fuel pumps on the engine ?

Sounds like an electrical issue. Stuff gets hot, expands, stuff isn't contacting correctly anymore. You mentioned replacing the "CPS", I'm assuming this is *crank* position sensor, and not cam position sensor. I would start looking there, first.
Thank you, will check the Cam Position Sensor.
A bad/disconnected cam position sensor won't cause a no-start situation, just a CEL. Check the crank position sensor. Another possibility is the "main relay". Some Hondas have issues with cars not restarting after getting hot because there's a fault in the main relay. I haven't heard of that on an aveo, yet...
Definitely check to make sure the car is getting spark and fuel, before you start replacing sensors, though. I could be a loose connection to the ignition coil, as well.
Absolutely , check the wiring and connectors first , before you start buying parts .
I replaced a crankshaft position sensor on a 96 Lumina V-6 , only to discover the real problem was a broken wire . :-(
Felt like kicking myself .

So , what was the final outcome ?
