my 05 chevy cobolt wont turn over. i have replaced the battery, coil pack, boots and plugs.
after I had got my car started I went to auto zone and got it hooked up to the computer it told me that it was misfiring, running lean, and a o2 problem. so I replaced the coil pack and the boots and it ran fine for a day and now I cant get it started again. please help me out on what the problem is on why it wont crank over
Are you saying the engine wont turn over or that it will turn over and wont start. Also curious as to why you didn't change the O2 sensor if it was showing bad? An O2 sensor can cause a run lean condition. If you get it turning over and not firing get a helper and have them spray a small quantity of ether into the intake while your turning it over. If it fires then you have a fuel delivery problem. If it still doesn't you most likely have an ignition problem.
