2006 CTS Cadillac won't turn over
I haven't driven my Cadillac for about a month and
before that I had just gotten fluids changed and a
new battery. I went to start it and the lights all came
on but went to start it and it cranks but won't fully
turn on. It dosent have a clicking sound like it would
for the battery. Also some white smoke comes out
the back exhaust (not a lot but a little)
I'm guessing just old gas or something?
