There are a lot of reason why your vehicle won't start. The battery could be dead, not powering up the starter, which is needed in order to start the car. There also could be a lack of fuel from a bad fuel pump. Another possibility is the lack of airflow in the intake system or even a problem with the ignition system not delivering enough spark to ignite the air fuel mixture within the combustion chamber. Lastly, mechanical issues such as the wrong timing or even bent valves in the cylinder head can cause a lack of compression, and in turn will not allow the vehicle to start. The best plan of action would be to have a qualified technician perform a diagnostic to pinpoint the source of your concern to get your car starting again.
