Ok I am new so I'm sorry if I'm posting this in the wrong spot but I need some help. Yesterday I took my 08 Grand Prix to the mall and everything was fine. When I went to leave it would not start, it would just keep cranking but would never role over. When I turn it on the gauges usually do their BIT test but now they just raise a mm or two for a second and fall back down. Everything electronic still works perfectly fine. I had a mechanic look at it this morning and we noticed the 2/5 coil pack was cracked, I replaced that and tried again but still nothing. I have tried the steps to reset when the theftlock is engaged but still nothing. Neither I or my mechanic are sure what is wrong now and I really don't want to pay the dealership to look at it so I was wondering if anyone here has any ideas. Thank you in advance for the help.
