If they had machined the fly wheel this may have damaged it to where the crank sensor is unable to pickup the speed signal from it.I have seen this done before and the fly wheel had to be replaced.If they did not machine it and they have a crank sensor fault they need to check wiring to the sensor for any issues needing repaired and if all wiring is o.k. then the sensor itself may need replaced to resolve this fault here.
