My 2004 Kia Optima won't start all of a sudden. I have had starter tested, battery replaced, alternator is good. What can I do?

It seems the starter is playing up.First check if your battery is charged fully or try to jump start and see what happens.If the engine start then it's either you need a new battery or else you need a replacement alternator.Test using a voltmeter if the actual altenator is working.Finally the last option is the starter motor that needs changing or fixing...Hope this helps.

Mr_Transcend I have the same promblem with my 03' Sorento to, same exact promblem. Have you gotten it fix and if so please can you tell me what was wrong with it. I would appreciate it very much.

I have worked on quite a few chevys and can tell you what I've found to work with this type of problem. When you replaced the starter, did you tug on the fusable links that connect to the solenoid to see if one of them was burned and loosing power? There are two or three short pieces of fusable link attached to wires that power the fuse block and other electrical circuits at the solenoid / battery cable connection that will stretch when you pull on them if they are bad. If they are, then you won't have power for the fuel pump, relays and other circuits to make the truck start.
If one is bad, cut the wire behind the link connection and put a **** splice and piece of wire on it with a ring terminal,and connect it to the solenoid. Turn on the ignition and listen for the fuel pump to buzz. The fuel pump is controled by the ECM and makes the pump turn on for 3 seconds to prime the system with fuel before starting the engine. One of the wires on the solenoid with a fusable link does this. If this works, your done.
If the truck won't crank when you try to start it, check the "S" terminal for power with a test light while someone turns the key. The "S" terminal on the solenoid comes from the ignition switch, to the neutral/backup / clutch switch to the starter. You'll have to check every point in between these for power to locate the problem. One bad connection or part will keep the starter from getting power to the "S" terminal. You can use a screw driver to test if the starter is working by touching the two terminals together.
While your under the truck, look at all the wires in the harness for any chafing or rubing, I once found a wire that rubbed through and was causing the problem.
Hope this helps, Craig

more then likely its a bad starter. or the cable to starter.
