I have a Pontiac g6 get sedan and it's not starting. We've put in new battery and starter alternator is new. It's hard to turn the key, it has to be jiggled profusely to turn and when you go to turn ignition the all cars lights on gauges flicker, wipers turn on and move with flickering but car won't start at all. I have been told it could be ignition switch or security system issues but I'm not sure what it could really be. Somebody please help me. I have 2 young girls ,4 and 11 months, to take care of by myself and need my car. Is it time for an upgrade or can I get it fixed?
