Well, the official word is that the battery was the problem. The fuel system had a leak down test performed and it was perfect. That eliminated the injectors. Next was the battery test which proved that it was faulty. 505 cranking amps out of 720. Most likely the weak battery was having trouble supplying all the voltage it takes to run these power hungry cars. Only time will tell. I'll update as I find out.
