I am a new owner of a 2001 V6 auto coupe. The car sat without running for about 9 months before I bought it. I jumped it, got it started and drove it home. Since parking it at home, even on jump it wont even crank anymore. I replaced the battery, the terminals and the starter relay, checked all the fuses and nothings blown. All electrical features in the car still work normally all the lights on the dash respond accordingly. Can anyone point me in the right direction on what steps to take next? Thanks.
