2003 KIA SORENTO WILL START BUT SHUTS OFF WHILE GOTNG DOWN ROAD.

SOMETIMES AFTER IT SITS IN DRIVEWAY FOR A COUPLE DAYS WITHOUT BEING STARTED, IT WON'T START FOR 3 OR 4 DAYS. THEN WILL RUN FOR SEVERAL DAYS WITH NO PROBLEM. TOOK IT TO DEALER, IT STARTED FOR THEM AND THEY COULD FIND NOTHING WRONG. SAID CALL THEM WHEN IT WON'T START AND THEY WOULD SEND A FLATBED AND THEN THEY MIGHT FIND SOMETHING.

Next time it want start...Loosen gas cap...If you hear it sucking air into gas tank it might be vapor locked....It's when your gas tank pressure becomes greater than your fuel pump..Cheap fix...Drill the smallest hole into the center of your gas cap...This could be your issue...

SOURCE: 2003 kia sorento will not re start after running around town

Engine temperature spikes when a car is shut down and many cars have an extra switch for the electric fan that will turn them on if the temp rises past a certain point.
That switch may have failed, making it necessary to allow the engine to cool off.
Your car may not even be equipped with that feature so I would suggest trying the following: When restarting soon after shutting off, slowly press the accelerator pedal completely to the floor and don't let up on it until the engine fires. Allow at least 20-30 seconds of cranking before giving up on it. The engine may be getting surplus fuel because of a problem with the computer or a 'cold start valve' that lets the engine draw more fuel when cold so starting it 'hot' it may be getting too much fuel to fire (flooding).

SOURCE: 2003 Kia sorento starts and then won't start

There is a black rubber button reset switch right next to the air box, press it sounds like the problem i had its a fuel pump reset (just in case of a wreck it kills the car) but there is a tiny ball in there and if it is rattled a little too much it will fall and you need to press the black looking button to reset it....took me like 4 months to figure it out

SOURCE: 2004 Sorento check engine/starting

hi
when the engine light come on engine computer detect problem in the engine.
I would like to advice you to scan the computer it can be sensors.
It can be EGR is blocked also air flow mas sensor.

Find a car-repair work shop which is using diagnostic equipment to solve problem.

Sounds like a vacuum leak. A lot of the stuff under your hood runs off of vacuum that your motor provides. Your brakes are no different. Your motor probably has enough vacuum to run fine but when you hit the brakes its just too much. I wouldn't push my luck. A car with a habit like that could make an accident real quick.

Kia Sorento

It could be a corroded ground cable. follow the neg cable from the battery and see where it bolts to on the body remove the cable and clean and sand the area reattach the cable and spray some battery terminal protector on it. I've seen this a lot on older sorentos

Kia shuts off while driving

If recharging the battery makes it start/go again then its a fault in the charging/battery circuit.
Solution 1. Check alternator. It should read over 14 volts across the battery terminals with engine at tick over. If its below that its the alternator thats faulty
Solution 2. Try a different battery known to be good. any size will do for a couple of days. Batteries sometimes only last 2-3 years. yoyrs could have been on since 2006!!!!!!

2003 kia sorento wil turn over but won,t start. after a while it will start up. l can drive down the road and it will cut off. after awhile it will start back up l checked the code and wasn,t getting any...

This is almost for sure the fuel relay. I do not know where it is on your car but I would look for it to be by one of the back wheels where road junk can get to it and corrode it. Once found not very expensive and very easy to replace.

Car stalls, will usually restart after sitting a while

Seeing as how you had a check light on,
what codes were present & did you diagnose
& repair them ?

Sounds like a bad fuel pump on the stalling or
no start
