Before you say it's the battery..it doesn't do it all the time. The click sound is similar to when the battery is low/dead. Sometimes it will start fine, other times it clicks while starting but starts fine. Other times it will click and not start. A few times it will not even turn over, just dash lights. If I wait a minute it will sometimes start. New ignition switch and starter did not help. Battery was relocated to the trunk since last winter. Tightened all nuts, and ground is clean.
