You don't need to crack the lines on a CR, they self bleed air from the system on cranking.
Either there is another bad injector or the one replaced is not istalled correctly or bad. Disconnect the heater grids and see if it will start with a shot of ether. If it does recheck the injector and torque tube alignment and snugging. Make sure the end of the TQ tube is not deforme dor it will leak and no start.
