I have a 2004 Intrepid 2.7l V6. I had to replace the starter last year for a similar issue. Now when I turn the key it does nothing. The radio comes on etc, but there's no noise from the engine. If I turn it a couple of times in rapid succession and then wait a few seconds and try it again, I can usually get it to start. It seems to happen more frequently if I've driven somewhere and then left it for a few minutes and try to start it again, like the store etc. Today it died twice while I was driving home. The engine just cut out and I had to put it in park and start it up again.
Could it be the starter again? Alternator? What should I check?
