I need a shortcut to find out why I keep blowing my engine control fuse. I have replace the engine coil pack. I think that there is a short somewhere. Pulled a code 43 from the OBD.

There are no shortcuts to find electrical shorts. Try unplugging the o2 sensors farthest away from the engine. One at a time, if there is a shorted heater circuit, it is possible that the o2 is blowing the fuse.
