1996 Mercury Tracer • 4 cylinder FWD Automatic •

96 mercury tracer cut off while driving, starter is turning but engine won't catch - fuel tank is full, all fuses okay, could the fuel injector relay do this? Or do I need a fuel pump? Other suggestions? The serpentine belt is okay, but I can't see the timing belt, nor did I find any pieces of one on the road.

You need to check to see if there is fuel and spark to the engine. If there is, check to make sure the timing belt didn't break.
