You have to first see if you get fuel and or spark. To check spark you need an extra spark plug to put into one of the wires and lay it on something grounded. When you turn over the engine you should see a spark from the electrode. If no spark you can take out your ignition control module and have it checked at you local parts store for free. They also will give you readings to check your coils to see if they are ok. Your ecm can be checked by a larger shop or at dealership shop. If you are not getting fuel you should turn key and listen for the pump to kick on. If you do not hear the pump you should check your relay first in the fuse and relay box. If the relay clicks when you turn the key on then I would say the fuel pump is bad.

My 2004 Kia optima shut off will driving. It cranks but doesn't want to start up. Can any body help me?

Well , it's probably missing one of three thing's , spark , fuel or compression ! Now you need to find out which one , pull a spark plug wire an hold a screw driver in the end of the plug wire an hold it close to ground an have someone crank the engine over ! don't hold the screw driver by the metal , you don't won't to get zapped . If there is spark spray some carburetor cleaner into the engine at some point ,vacuum hose ,air intake , the throttle plate would be best , there is usually a black tube going from the air filter box to the engine ! A couple of clamps holds it on , take it off an the engine side you should be able to see the throttle plate ! If it tries to start after spraying carb. cleaner in , you have a fuel delivery problem ! Fuel pump relay , fuel pump driver module or the fuel pump it self is bad ! Now if you have spark an sprayed carb. cleaner an it did not try to start you need to check engine compression ! The timing belt may have worn enough for it to jump time a little causing it to be out of time ! Back in the 80's the little cogs on the belt would wear off an the cam shaft wouldn't turn . Back then it was easy to check by taking the distributor cap off a see if it would turn while cranking the engine !

Shut down while driving down road and wont restart what could be trouble? Tried to restart but now it just turns over

Spark and fuel. First check the spark to your plugs by pulling a boot off and connecting a spark tester that you ground to the engine block. The old mechanics just rig a screwdriver inside the boot and hold it a 1/4" from the ground while someone cranks the engine. If there is no spark CHECK FUSES FIRST . Then look to test ignition components. Crank sensor, cam position sensor, etc. IF THERE IS SPARK - Check the fuel Relay. All of these components can usually be tested free at the local parts stores. Lastly a test of the fuel pump is in order. Try a direct voltage connection to see if it runs.
Good Luck!!!!!

Check there is power to the fuel pump and the fuse hasn't blown or the relay damaged.

Car wont start

If the engine cranks the starter is doing its job.
You would need to check for fuel pressure at the injectors.
Its possible the pump was clogged up or overheated when you were driving it low on fuel. The gasoline keeps the pump cool and lubed.
The only fuel filter for your model is inside the gas tank.

This could be multiple issues.
1.) timing belt
2.) Crank sensor
3.) Fuel pump (although usually they do not just die they get weak)

Check these let me know.
