check the current coils, fuel pump.

I've never worked on a Kia Diesel, but the pump is either on the frame rail or they stuck it in the fuel tank just like on a car.

Do you have any check engine lights on? Most diesels have a safety feature that shuts down the engine and puts it in "limp mode" when there is a problem somewhere . It will stay in limp mode till repaired and the code cleared. You should get a code with a diagnostic.

One of the first things I do when I get a new-to-me vehicle is to get a Chiltons/Haynes repair manual for that make/model/year. These repair manuals have the codes, troubleshooting guides, and even tell you when you may well be in over your head. And yes, I keep the manual when I get rid of the car. You never know if you may well buy another. I have Kia repair manuals, but they are for Sephia/Spectra. And to my knowledge these sedans did not come with a diesel engine. I didn't even know the Sportage could be ordered with this powerplant. Just checked my books. Neither address diesel powered Kias. You will have to find a repair manual the specifically addresses Kia Sportages with the diesel engine.

blow by, piston rings are worn out or your turbo isn't working properly.

Hi my kia sportage 2.0ltr diesel dont rev over 1000 then cut out. What can i do

There is a check valve under the vehicle on passengers side of vehicle,near the axle,this is most likely the problem,it is allowing the fuel to drain back in the tank.This part is only available online,or at the Kia dealer.I hope this was helpful,and if so,please rate,thank you.

timing to retarded feul filter clogged

how long since the glow plugs were tested?indirect injection engines still require glow to start allbeit less,time,when hot ,just a quick test ,give it a small squirt of starter fluid in the air cleaner [with the filter out ] if it starts strait away then bet your booties it needs glow plugs. i will bet mine without doing the test-------- good luck
