Try cracking one of the injector lines to see if it is squirting fuel, might have sheared key off the pump drive or something popped apart. You should also check if it has a fuel cutoff sol, it may have failed. If the engine shuts off with the key then yes it has some sort of electrical fuel cutoff. If it stays running until you pull a lever or rod then it is manual cut off and you may have broken something if you get no fuel squirt with a cracked injector line.
Remember you need fuel, air and Compression so if it has a Compression Release check that as well.
