My NX2000 has recently developed a starting problem. When I attempt to start the car it turns over for a few seconds, then it stops all of a sudden and sounds like it locks up. After that it just clicks and won't turn over at all. I took the starter out, thanks to directions I found here, and when I hook it up to a battery it appears to turn over just fine. I'm hoping not to have to buy an new starter. Any ideas as to what the problem might be? Thanks for your help!
