"Bad Booger" 02 Black ZO6
02-ZO6-19,000 miles. Have had starting problems several times over 3-4 months. Turn key, everything working but no turn over. Turn key numerous times and shazam, it starts. Yesterday would not go, had to get a wrecker. He tried jumping it, no go, he tapped the starter and vrroom. He told me the battery was no good (it's about 3 months old) and it engaged the starter to the flywheel but not enough power to turn it over and stuck. Went directly to Advance Auto, 13.8 - 14 volts on the way there so the alternator is OK, they checked the battery and said it's OK. I'm lost???
