Cam chain jumped ? won't start
 

my clutch disc exploded and took out my crank sensor as well as stopping the motor dead when it blew.
New clutch and crank sensor and it wont start.
1) Could that have caused the cam to jump a tooth or two?
2) If I have compression in all cylinders, could the chain/cam timing be ruled out ?
3) could the sensor in the cam cover be the culprit now ?
4) test procedure for the cam cover sensor ?
