Code P0304

I’m back. So now my Kia Forte Ex has started kicking code P0304 which is a problem with cylinder 4. Considering the findings of my prior “Gas Cap” discussion & what my mechanic found to be the problem a broken ground wire in the middle of wiring harness for cylinder 1. Is it possible to replace the whole fuel injector harness & if so where can I purchase one? Any guidance is greatly appreciated.

You could easily splice in a new section of wire if you can’t find a harness. I’ve done it many times on my previous cars. You can get proper gauge/coloured wire at comprehensive auto stores. If you don’t know how to solder, you can use crimp connectors.
Can we get this thread back on topic ffs.
