Engine problem
2002 Chevy Blazer V6 Four Wheel Drive Automatic 105000 miles

I can hear a loud knocking noise coming from the engine. After looking around the engine I beleive it to be a problem with the oil pump. I've located the oil pressure sending unit to test this theory. The problem im having is, that when I unplug the harness to the unit, the car wont start. Please let me know if you have any suggestions or new theories about this problem. Thank you
