Kia Troubleshooting Questions? Ask a Mechanic
Hi Im David. is the check engine light on?
do you have a scan tool?
normally when a car stalls after its been running a while. the crankshaft position sensor is the culprit. it was scanned but no code? where did you have it scanned at?
but it will start after it cools down?
oh ok. the fuel pump may be overheating after running for a while. have the fuel pressure tested.
you have to hook up a fuel pressure gauge to the fuel rail test port. turn the key on and see what the gauge reads.
somewhere around there.
if the fuel pump overheated yes.
and if the fuel pressure isnt to spec
that can do it also, but you should have a code for it. or you need to pull it off, and test it.
have the pressure tested. until that is done im not going to guess about anything else, especially since you have a check engine light on and no codes??? you need to take it somewhere else to have it scanned.
wow. thats a huge problem!!! is it noticeable on the ground??
what you need to have done immediately is a pressure test of your coolant system to see if its leaking externally or internally.
you have multiple issues for sure. if the coolant is leaking internally you can have major engine problems like a blown head gasket, cracked head, cracked block......it would definitely cause the engine to stall for sure. but i also believe you have fuel pump problems too.
ok and you are welcome.
sorry for the delay. had an emergency. how did they determine the injectors are bad
so the coolant leak is external and the #1 and #4 injectors are bad? did they reconfirm the injectors with a noid light? did the unplug those injectors and see if the engine didnt change rpm?
ok. then have them replaced
have them replaced. it'll fix it. have that darn coolant leak fixed too
