Saint,
Jerry is correct!! As a past factory trained Cadillac electrical technician, I learned to ALWAYS check the grounds and fuses before jumping in on a major operation. Jumping to conclusions without testing leads to unneeded parts replacements and cash out of your pocket. As far as the possibility of two starters being bad, I would not be surprised. Where did you get the starters? Are they rebuilt, remanufactured or new? I have always had the best luck with NAPA when it comes to electrical parts. Are you sure your ignition switch is working in the start position? I have had ignition switches come apart inside or wear through the contacts. Key turns fine but no fire. Just another possibility to look at. Did the newest starter bench test ok? Electrical is not easy to diagnose over the phone or e-mail or texting. Can't tell you how many times people have asked me diagnose on the phone, or listen to a noise over the phone. The last guy that asked me to listen to an engine noise over the phone and tell him what was wrong with his Jeep Cherokee led to the answer..."You've got a loose nut behind the wheel." After I said it, I thought it might be offensive, but the guy had a good sense of humor and LOL. After I looked at the Jeep "in person", it turned out to be a bad belt tensioner. Replaced the tensioner , idler pulley and serpentine belt. All was well.
