My 2005 Kia Optima wouldn't start after seeming to get less power during three stops throughout the day. Finally, it wouldn't turn. I figured it was the alternator, but the mechanics checked the charging system and all was fine after getting the battery recharged. Two weeks later, exact same thing. What is the problem if not the alternator? Thanks to anyone,

flassed less engine power wth?????????
Flashed reduced engine power ! Electronic throttle control problem ! Your best bet ,take it to a GM dealer , buick , cadillac , GMC . You do not have diagnostic test equipment or knowledge to even diagnose this.
It would help to know what kind of "won't start" you mean. Is it just ticking? Low battery voltage. Considering it started after getting your phone, probably not that. Is it cranking slow and not trying to catch (where it spins faster as the engine is firing but not fully catching and entering a run state)? Is there nothing at all, just shuts the accessories off and does nothing, no click, tick, hurk, jerk?
I had a Malibu that did not like starting too fast. As in if you flipped the key switch straight to start the fuel pump wouldn't pressurize properly or something. But if I turned it to on, gave it a second (you can usually hear when the fuel pump stops running once the system is up to pressure) then hit the starter it kicked over just fine.
It is probably one of three things. It isn't getting a proper spark, proper fuel, or proper compression. Good luck!-------------------------------------------------------------------------- VAS 5054A
If it's a stand-alone pulley, it would have bearings which may be worn and about to fail. If it's a pulley on a component, like a power steering pump pulley, the component may need troubleshooting.
Only need three things to run. Fuel, spark and compression. If you have spark and injector pulse you might want to compression test the suspect cylinder. A leak down test with compressed air with the adjacent spark plug(s) removed wouldn't hurt either to verify no bad head gasket. Good luck
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.
