I took my car to Autozone to have it put on the computer for the miss. It has a code of P 0200 which comes up a fuel injection circut open as well as P 0301 which is a misfire on cylinder #1. How do I fix the fuel injection circut open code which I assume is the root of my problem

An easy (free) check would be to move the #1 injector to another cylinder and reset the codes.
If the problem moves to the cylinder you moved the injector to, I would replace that injector.
If the problem remains on the #1 cylinder, you have a wiring issue or other failure.

Reason: added schematics for a 99 coupe which might help
I had just sent the injecors out to witchhunter to be rebuilt and they passed with flying colors. I have also unwrapped the harness om the #1 cylinder side and I did not see any cracks or burn marks on the wires. I have wiggled the harness pulled it and moved it and it didn't seem to make a difference

I would still try to move the injector to another cylinder and see if the problem moves. It is possible that the #1 injector could have or is randomly failing. Otherwise it looks like it could be a loose connection or pcm issue.
