change the plugs and wires

[cobalt camaro]

Just like everyone else is saying, check your grounds, make sure they are clean of any rust or paint or anything like that, make sure all your sensor's are plugged in, and make sure none of your spark plug wires are cracked, a cracked spark plug wire, can ground itself out on the engine, causing it to not start at all. But do use the OBD II programmer, or i don't know if autozone still does it but they used to scan your car's computer for free, and be able to tell you what codes have been triggered. Well good luck man, let us know what happens
