I have a 2000 Elantra. Car's new battery is fine, has new connectors still will not start at times. Alternator is fine. Will not start every time. Won't turn over. No dash lights, nothing. Help!!!!!

 

Sound like a bad or loose connection somewhere, possibly on the starter motor or could be a bad ground connection.
Best of luck, Chris.

 

Have you checked your plugs at all?

 

i also have a 2000 elantra and was having the same problem. i replaced the starter and now its working fine. in my starter the solonoid was still working but nothing else was, all i heard when the key was turned was a quiet click.
