1 Answer

are you sure the flywheel is turning...often automakers give you a small opening where the flywheel is exposed for using a timing light to find TDC...this is actually turning...but the valves and timing chain is not? is this the case? if this is the case, yes something major has become disconnected...cracked crank is a scenario...crate engine? https://www.google.com/#q=1992+GMC+Sierra+1500++crate+engine&tb m=shop
