I have a 2004 Pontiac Grand-Am SE. I recently had some repairs completed (intake manifold gasket, tuneup, radiator flush, spark plugs and wires changed). I went to drive my my and it will not start. I took the battery out and took it to a local store and they said the batter is fine. I put the battery back in the car and it started. Tried to leave hours later and the car won't start. Please help.

It sounds like there may be a problem with the anti-theft system. Best to have the dealer check it out.
