My mother has a 2004 Pontiac Grand Am, with just under 80k miles. It starts very similar to the solstice, you turn the key and release and the starter will crank the motor until it fires up or times out. Lately it's been taking a lot longer. She had to turn the key 12 times today before the car would fire up. The engine is turning over just fine, just not catching and running. The car is stock, I change the oil regularly for her and hasn't had any mechanical issues. I plan on doing a basic tune-up on it this weekend, plugs, wires, filters, and cleaning the intake and related sensors. Would this help or is there something else I need to look at?
