Hi Im David. is the check engine light on?

Customer: replied 1 month ago.
it is on
Expert:  david craig replied 1 month ago.

do you have a scan tool?

Customer: replied 1 month ago.
It was scanned but no result found
Expert:  david craig replied 1 month ago.

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?

Customer: replied 1 month ago.
At a nearby shop in my locality
They deal in kia cars
Customer: replied 1 month ago.
after it stalls the engine wont start but would crank
Expert:  david craig replied 1 month ago.

but it will start after it cools down?

Customer: replied 1 month ago.
Yea untill it totally cools down.. but sometimes it wont start at all
Customer: replied 1 month ago.
One mechanic removed some big hose from the engine and blocked it with a cloth soaked with petrol and the engine came on. But after some few mins it would go off and i have to start it up by that same way
Expert:  david craig replied 1 month ago.

oh ok. the fuel pump may be overheating after running for a while. have the fuel pressure tested.

Customer: replied 1 month ago.
it has being. But it seems good
Customer: replied 1 month ago.
But how do i test the fuel pressure
Expert:  david craig replied 1 month ago.

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.

Customer: replied 1 month ago.
Oh ok
So it should read at 45 to 40
Customer: replied 1 month ago.
I just changed the fuel pump filter
Expert:  david craig replied 1 month ago.

somewhere around there.

Customer: replied 1 month ago.
that can be the reason why the car stall and wont start?
Expert:  david craig replied 1 month ago.

if the fuel pump overheated yes.

Expert:  david craig replied 1 month ago.

and if the fuel pressure isnt to spec

Customer: replied 1 month ago.
But what about the crank sensor
Expert:  david craig replied 1 month ago.

that can do it also, but you should have a code for it. or you need to pull it off, and test it.

Customer: replied 1 month ago.
A mechanic told me it can also be the control board system
Expert:  david craig replied 1 month ago.

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.

Customer: replied 1 month ago.
Ok i would get it scanned again and have to feedback sent to you
Customer: replied 1 month ago.
one thing. Anytime i put water in the coolant it takes up to 12 hours it all gets finished. Is that a probable cause.. that is to say the leaking is a cause?
Expert:  david craig replied 1 month ago.

wow. thats a huge problem!!! is it noticeable on the ground??

Customer: replied 1 month ago.
No it is not
Customer: replied 1 month ago.
When u pour water in it by some hours or lets say a day the water drains out but no visible leakage. One mechanic noted a very small leakage near the radiator but i was in doubt whether the water leaking can be the cause of the engine going stall and not starting
Expert:  david craig replied 1 month ago.

what you need to have done immediately is a pressure test of your coolant system to see if its leaking externally or internally.

Customer: replied 1 month ago.
that can be the reason why it keeps stalling
Customer: replied 1 month ago.
I have got it to the mechanics now so we are working on it. This morning i had difficulties starting it up till i used the fuel to the hose. And it stalled agin when my speed was on 60-80 and had it turned on again by the same manual way
Expert:  david craig replied 1 month ago.

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.

Customer: replied 1 month ago.
Ok then i would let them check all now and get back to you thanks
Expert:  david craig replied 1 month ago.

ok and you are welcome.

Customer: replied 1 month ago.
Hello the mechanic said it is the injecters. Can that be a cause
Expert:  david craig replied 1 month ago.

sorry for the delay. had an emergency. how did they determine the injectors are bad

Customer: replied 1 month ago.
They scanned it and said the injecter 1 and 4 is bad
Customer: replied 1 month ago.
i told them to wait and not buy new ones till i get to you
Customer: replied 1 month ago.
you determine whether the injectors can cause such a problem
Customer: replied 1 month ago.
Also we saw the leakage. It was external
Expert:  david craig replied 1 month ago.

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?

Customer: replied 1 month ago.
They unpluged the injectors and claim they tested and saw just 2 work
Expert:  david craig replied 1 month ago.

ok. then have them replaced

Customer: replied 1 month ago.
After they unpluged the injector they didnt start the car
Customer: replied 1 month ago.
I want to confirm from you if the injector can cause these problems so i go ahead and buy new ones
Expert:  david craig replied 1 month ago.
