NO, there is no switch. Check for fuel pressure and spark. You can check for both at once by spraying some carb cleaner into the throttle body as you crank the motor, if it tires to start but won't stay running, you have spark, but no fuel, if it does nothing, then you have no spark or mistimed spark and possibly no fuel as well You must resolve the spark problem first, then that may take care of the fuel issue, for example, if it is a defective crank sensor.
