Compression test that cylinder. Could be a bad valve. Also pressure test the cooling system. With your cooling system pressurized start the engine. If the needle on the pressure tester gauge bounces you've got a blown head gasket. If both these tests are ok, using a 'noid light check that the injector is getting the trigger signal to spray fuel. If not, check the wiring going to that injector. HTH. - Jim

Also check the spark plug, plug wire, and ignition coil pack.
