New oem injector o rings/ seals

Now my issue is my cyl #3 pigtail is grounded on both the ground and the power wire. With the key not in the ignition I get constant ground tested via test light. I have swapped ecu's and I chased wires (not to far into the harness since the power and ground wires split off I assumed it was the harness because it didn't happen till I fixed my air leak due to crappy cai couplers so I swapped it out for the oem intake. I'm stumped into what it could be and need help.

Now I don't need dumb answers because I know most of the common issues and I have addressed most (minus the harness which again I don't believe is the problem but a possibility) I'm stumped and need serious help to get my car back
