Ok, I am not sure on the year, possibly 2005 but GM put a fine screen type basket under the oil pressure sending unit that gets gummed up. Just have to pull out the oil pressure sending unit and fish that screen out and clean it good. You'd want to replace the oil sending unit since it would be out. Clicking on the starter is either bad connections, low or bad battery, or in the charging system not charging the battery.
