I am working on my brothers 2005 4.2l a6. I changed the front drivers wheel bearing, and now it won't start. I have owned and worked on my wifes 2001 a6 4.2 for 7 years, I know her car, the 05' is a little different. I left the key in the ignition for 3 hours, witch drained the battery not dead, but would not start. I put a charger on it, now it rolls over but won't start. Is there a fuel shut off for when I jacked it up? Is it possible it is flooded, from nor starting when turning it on, 5 times it 6 hours? I just want it out of my garage, and he wants it back, any help would be appreciated.
