I was looking though my the FORD tech CD and found out how to pull the codes from the PCM. After hooking it up, I went to observe the check engine light and it never comes on. I then tried the instructions for using an analog VOM and when I turn the key on, I get 12 volts continuously instead of the bouncing meter I would have expected to display the codes. Also, I noticed that after I tried this test, the coil got very hot. This is sounding more and more like a wiring problem within the harness, but I don't know where to start diagnostics on that.
