The crank sensor fault could still be showing from the old sensor unless you cleared the fault when you fitted the new one. But there is another possibility - did the sealing washer come out with the old sensor - if not, and there was also a washer on the new sensor the signal would be very weak.....easy fix, though.
With regard to the other fault code, its really down to checking through the possible issues listed - lambda sensors, split hoses, etc.....mostly they would affect how it ran, rather than stopping it running.
