shattered crank shaft pulley

[maddie]

Hi i have 2007 1.3 petrol vvti euro the crank shaft pulley came off and engine made funny noise.I know this runs aux items.Can this damage pistons and valves or can i get new replacement pulley and bolt and all will be okay.This happened after i replaced the alternator and the belt was not overtight.i have found no key so this might of begun to losen before hand.Am i right i can start engine just for short peroid with out sepentine belt and no crank pulley ? or does it need crankpully to start.My point is the engine dead i dont want to spend lots of money onit mainly because i have not got it.i am quiet handy with my hands but not sure what to do to test or look for before i turn it over.Any help or advice please
