Damaged CKP sensor connector Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway) Sensor output open Sensor output shorted to ground Sensor output shorted to voltage Failed crank sensor Broken timing belt Failed PCM are probable causes
if this helps.. I had the 1998 model S70. the water pump was driven by the timing belt. you had to take the timing belt off just to replace the water pump. it was just a simple bolt on replacement. the only difficult issue is resetting the hydraulic tensioner on the timing belt. the hydraulic tensioner has to be completely taken off and compressed VERY SLOWLY in a vise. then insert a very hard drill bit or (special volvo tool) into a keeper hole, reinstall hydraulic tensioner onto car and reinstall timing belt.very quickly remove drill bit from keeper hole in tensioner and the tensioner snaps back out to put tension on belt. and you are done.
just put a compression gauge on each cylinder that will let you know if engine has a bent valve, gauges are relatively cheap. if the belt didn't have anything to do with your timing belt i doubt you have a bent valve, any check engine light? do you have spark? fuel pump turning on when key is turned to on position?
If its just a regular drive belt its impossible for this belt to "kick back" and bend a vale. However if this was a timing belt its quite possible to bend valves if it breaks. You problem could be a crank sensor that may have gotten damaged when this belt broke. If the crank sensor is damaged it won't send a reference signal to to computer therefore the vehicle would not have a spark to start. Godd Luck
