The starter on my 2002 Taurus with 3.0 OHV will engage but not turn. I had the battery checked and it needed replacing. Replaced battery and it still won't start. I attempted to remove the starter, but it appears to be blocked by the catalytic converter. Cannot remove from top or bottom. I am not a mechanic, but can do basic repairs. Has anyone had problems removing the starter, if so any suggestions on removing. Also, since I can't get the starter out to bench test, are there any other possible issues that can be causing this?
