2006 Pontiac Grand Prix will intermittently not start after new battery installed.
I recently had a new battery installed on my 2006 Grand Prix because of intermittent problems with starting the car. It would sound like a normal start but not engage fully. Sometime it will take 2 tries to start it, sometimes up to 12. The new battery did not solve the problem so I took it back to the repair shop, they checked the starter, altenator, connections to the battery and then hooked it up to the computer for diagnostic testing. All systems came up normal. I did have the ignition switch replaced a couple years ago during the recall and wonder if the switch could be the issue. Any ideas?
