I have start the engine and inspect. Didn't have any wobble.Did you see my comment about the wobbly crank pulley? You should be able to visually inspect the pulley. Start the car and look at the pulley turn. If it wobbles then you potentially have your culprit.
China crank sensor - but was it made for your specific engine or a generic VDO sensor?
Yesterday I checked and try wobble the crank sensor itself at the bottom side and the car died same as the car usually went dead.
Not sure as I never see the package.
