if the battery or charging system is not bad, replace the camshaft position sensor 

Possible causes

- Faulty Camshaft Position Sensor

- Camshaft Position Sensor harness is open or shorted

- Camshaft Position Sensor circuit poor electrical connection

- Faulty starter motor

- Starting system circuit

- Dead (Weak) battery
