    my 2004 Kia Optima will only turn over 1/2 a turn and this is very slow. the battery is only a month old. Jump starting didn't do anything. Terminals look clean and are tight. With the head lights on, and you try to start it, the lights go out.

    Also, can you tell me where the starter is located?

    My car will not start. When I stopped at a red light, it turned off. I tried replacing many parts and even got a new battery.

    We stalled when driving through a parking lot. The car would turn try to turn over but not be able. We were told it might be the timing belt but we don't have the money to find out for sure.

    My car did the same thing. The timing belt was shredded. We took the cover off the engine and the casing the timing belt is in was busted. The timing belt casing was located to the right bottom side under the engine case. Easy to spot because the casing was broken. The Kia place sayed it was $352 without tax just for the part. But I found a local place that carries lots of parts that has the timing belt for under $68 without tax. I live in Panama City the place is called Wiggins. They always have lots of parts we need at good prices. Bad part is the work will take a whole day.

    My 2004 kia optima quit on me going 60 on a major highway, my service engine light came on and it just died. It tries to crank but want, waiting on the mechanic to tell me what is wrong.

    2004 optima will start, run for 5 seconds and die.

    I have same problem, car stalls, will not start. We replaced the crank shaft sensor, and set the timing. Timing belt is good. We also replace the cam shaft sensor, car still will not start. Originally after we replaced the crankshaft sensor the car stated right up and idled nice for three minutes or so; soon as we raised the rpms the car shut down. I am working with a well experienced tech, and this has us both baffled.

Plug an OBD II code reader in and you will most likely see that it has an issue with either the timing belt or the crank position sensor. either of these will cause you to stall/not start. If timing belt jumped teeth or knock sensor failed the car will either run rough or not start at all.

Change your crankshaft sensor located behind lower timing belt cover. The way I check it is to unplug the maf and see if it will start if so stop the engine and do a diagnostic 3 DTC's should come up on screen ,one would be the crankshaft sensor. This should be done by a experienced tech.

2004 Kia Optima won't start. Took off from stop and the car died. Now it cranks over but will not start.

Often caused by broken timing belt. Recommend removing the timing cover and checking camshaft timing marks. If you need instructions, please send engine size and type.

Try the ignition switch,

For the Crank sensor there is a small metal disc that mounts behind the sensor if that is cracked or dammaged or installed backwards you will get same results as if it wasn't Make sure the timing marks line up on your timing belt.
