* Blown Head Gasket: A blown head gasket can lead to a loss of compression, preventing the engine from turning over smoothly or at all. It could also allow coolant to leak into the cylinders, leading to a hydro-locked engine (which absolutely prevents starting).
* Bad Fuel Pump: A bad fuel pump means no fuel is delivered to the engine. Without fuel, the engine won't start.
Why it's unlikely to be *only* these two:
A no-start condition usually has multiple contributing factors. For example, a blown head gasket *might* also cause issues with the ignition system (due to coolant getting where it shouldn't), making it harder to diagnose just the head gasket.
In short: While both problems *could* individually prevent starting, a more thorough diagnostic check is necessary to determine the actual cause(s) of your Camaro's no-start condition. It's best to have a mechanic check it.
