While you may have a bad head gasket, that is not a reason for you not starting. The engine will start (even if with blown head gasket), it just doesn't run right, but it will run.

Follow this diagnostic.
Check battery and starter.
Check fuel pressure.
Check fuel pump circuit.
Check fuel pressure regulator.
Check fuel injector circuit.
Check fuel evaporative emission circuit.
Check Idle Air Control Valve-Auxiliary Air Control (IACV-AAC) valve.
Check ignition timing and ignition circuit.
Check timing chains.
Check Exhaust Gas Recirculation (EGR) valve.
Check Positive Crankcase Ventilation (PCV) system.
Check Camshaft Position (CMP) sensor circuit.
Check Mass Airflow (MAF) sensor circuit.
Check Engine Coolant Temperature (ECT) sensor circuit.
Check main power supply and ground circuits.
