Sonata starting problem

My 2005 sonata has a peculiar problem. it doesn't start after running for a while(say for an hour) but not every time,once in week sometimes once in a month. it cranks but will not start it starts when i remove battery connections for minute or 2 and reconnect . can anyone help me.
hyundai mechanics (here in india) tried all they knew still couldn't slove the problem.

Hello there , I'm not sure about Sonatas , if you have changed your battery or disconnected it , some vehicles like Fords around the 2000 year mark need to be calibrated , this may be achieved by turning your ignition on putting your tran in drive with your foot flat on the peddle and hold for 3 minutes and then turn ignition off and then back on with the car in park and no peddle , do not start car to do this just ignition on ! Good luck all so it may be cheaper to buy a work shop manual rather than taking your car to a work. Shop , best is - Haynes Work Shop Manual - Regards Graham ...

you might be getting excessive heat soak for the old starter 9 yaers is a good run it might be time to pony up for a new one but i would definetly check all the connections corrosion on terminals and rusty grounds hope this helps

Hard start and I think it may be the timing belt


if it was the timing belt it would have crunched the valves by now ,i do feel you have a sensor problem?? but which one i honestly couldnt tell you.valves tapping is caused by not changing the oil regular and they clag up and do not self adjust,so change oil every 6000miles ,try taking it to the main agent because a dealer fitter will understand their own particular make of vehicle better than myself when it comes to sensors and peculiarities of the model

My 2005 sonata starts after trying several times. It just turns over like a car out of gas, then usually on the third time it will start.


Sounds like its either fuel or ignition. Have someone turn the car over while you sniff the exhaust.
If it smells of raw unburnt gas , fuel is not the issue , your problem is most likely ingition. Car might run rough at first when it does start , due to being slightly flooded.
If no gas smell probably a fuel problem. Possible low fuel pressure , or no fuel injection.

Sonata starting problem


could be a bad cable connection. clean the battery terminals and the clamps on the battery cables. if it continues to do it, check for a bad ground cable from the battery.
