2003 misfire

Pulled the codes and had a #2 misfire. Started the troubleshooting. Changed the plug, plug wire coil pack and also changed the injector. Still have the misfire. I have spark so it has to be something with the fuel I'm thinking. Maybe the injector wiring harness. How do you check it. If anyone has a wiring diagram and an ohms test on the injector harness that would be great. What do I do next?
 


Did you check down in the injector housing to see if there are any foreign objects in there blocking flow of fuel?
