First thing that comes to mind is air in the fuel system. I would have tried to prime the system first. Also, I know that south carolina is hard on batteries because of the heat. (my parents came down to visit me while I was stationed there and they had a battery go out, but the car didn't even crank) You could have had a bad battery. Do you have any mods on it or is it totally stock? I know there was a TSB on the injector harness going to #2 and #7 injectors. There has been a problem with them chafing. This sounds more like a reason for it to be failing. Let us know what the dealer says. Also, Welcome to the forum!
