Timing Chain Replacement

93 Del Sol 1.5 engine 135,000 miles. Stopped running while driving to work. Engine cranks normal but no fire. Is it possible could be timing chain? If so any estimates how much to replace? Where is fuse or module for fuel pump?How do you determine if it is timing chain? Please give options!
Thank You.

Sol's didnt have timing chains, they had timing belts. If it snapped, you would have known. Was it dhanged at 90K?
