That's what I would say if fuel delivery and spark are ok. Timing chain. pop a valve cover off and turn it over too see if the rockers move.

leave the valve covers on. just check for spark or pull the cap off. no spark/rotor turning, broke cam or chain.

are you getting spark? if not, check the ignition module in the distributor or possibly the coil.

Doh! <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> Good point. Could just be a broken gear on the distributor.
