Try to narrow it down to a fuel issue or ignition issue. Does it start right back up, after it cuts off? If you have to keep cranking it to get it running again, suspect a fuel problem. Change the gas filter and have the fuel pressure checked. Also have the computer scanned for trouble codes-a sensor may be problematic-something as simple as a Coolant Temp. sensor, or the idle air control.
To check your ignition circuit, check for spark at the spark plug right after it cuts off. You need to see a strong, blue spark to know the ignition is good.

REMOVAL OF THE PLUGS:

Do not attempt any maintenance on spark plug if engine is hot. 
1. Disconnect negative battery terminal. 
2. Carefully remove high-tension leads. 
3. Use compressed air to blow any dirt or debris from around spark plug hole. 
4. Check that spark plug fits squarely in spark plug socket and remove spark plug.

Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug. 

INSTALLATION:

1. Install spark plug into cylinder head.

Tightening torque : 18~22lb-ft (25~30N·m, 2.5~3.0kg-m)

2. Reconnect high-tension leads. 
3. Reconnect negative battery cable. 

Hope this helps and simple to understand. Good luck

SOURCE: does my 2003 kia optima have a fuel pump cut off

There is a fuel pump relay and it is;

If you remove the trim panel around the radio, its located behind the ash tray (no need to actually pull the radio). There are two relays, the lower one is your fuel pump. The other is the main relay.

You can try disconnecting the battery for ten minutes and that may resolve the issue as well. I cannot find the fuel shut off switch on that model. There is a fuel pump fuse that is located in the fuse panel and that may be bad, I would recommend that you check that first before you do anything else.

could be spark plugs, dirty fuel filter, air filter, Mass Air Flow Sensor. bad spark plug wires. Dirty throttle body or injectors. I would start with the cheapest and work my way to the more expensive things if it doesn't improve.

Although is could be a fuel filter, it could also be a fouled spark plug, or a bad spark plug wire. Once you've ruled these things out, the problem could be the TPS (throttle position sensor). This controls your idling speed under all conditions. A faulty TPS will usually idle fine when the engine is cold but once warm, will tend to sputter and in some cases, stall.

I have a 2000 kia sportage that cranks but will not start what might it be?


When en engine won't start, there could be a number of things wrong. An engine requires air, fuel, and spark to start. You need to start by checking for spark. Take out one of the spark plugs and plug it back into the wire. Have somebody else turn the key while you hold the plug up to something metal on the engine, right next to the spark plug hole will be fine. You should see a bright blue spark, if you don't then you probably need to replace the spark plugs. You can do this same thing with any of the spark plugs. If you don't have spark on any of the plugs, get back with me and we'll go from there.
