I would advise starting with testing for a spark..that is easiest and involves little on your part.
Breaking or jumping a timing chain is rare in that particular engine.. If time is jumped you most likely have broke the pin that holds the gear on the dist shaft.
BUT!! Since the thing is a fuelie usually such a non running problem can be traced to a common sensor that advises the computer.. A mechanic should be able to find the problem in short time. PLEASE don't tell him of the $1,000. Your repair should be 15% of that..
