Open the fuel line at the #3 cylinder and see if fuel squirts out with it running. If not, Injection Pump problems. If so, and you've succesfully eliminated the injector, the next step is to pull the cam cover to look for a collapsed lifter or check compression. You can also do a quick-and-dirty compression check, crank the engine with the stop lever down and listen for an uneven crank of one cylinder without compression.
