I own a 2004 Elantra. The other night I noticed it took longer than usual to turn over. I figured it was the cold weather and I could take it to Advance Auto and let them check the battery the next day. I did that and they said the battery was good. It ran fine that day and the next. This morning I went to start it up and it would crank and crank but not turn over. I got out the jumper cables and finally got it to turn over- and right as it started I heard a popping sound. Not sure if it was a backfire or what. I took it back to the parts store and they re-tested it and said the battery, alternator and starter all appeared to be good. At this point I am beginning to scratch my head- Do I have a ghost that is draining the battery somehow? Could there be a bad spot on the starter? Someone else suggested a fuel injection issue or something of that nature- maybe a relay switch going bad. Any thoughts would be appreciated. Today it sat for about 7 hrs plus and it started right up this evening- Ran fine. I shut the car off and tried to start it again and it started up with no problem whatsoever. ---

If the engine cranks over and does not start my first guess would be crankshaft position sensor. It would be good to have a code reader plugged in at the time of the problem it may show up as a pending code. It seems crankshaft position sensor a prone to failure on Hyundai ---

It has only happened one time so far- I will be vigilant about having it checked if it happens again or when I take it in for service next, which should be in the next week or two- Thanks!
