If you loosen the high pressure lines at the injector nozzles, so you have fuel squirting at all three cylinders? If no squirting at the one that is not firing, the matching injector pump, in the body of the injection pump has failed.

# ***** is the pump , and has one for each cylinder.

If fuel is just dribbling at each each high pressure line, then you have insufficient fuel to the injection pump body. Plugged fuel line or filter.
