See what code it has for the fuel gauge problem
Install a fuel pressure gauge and see if the pressure is bleeding off causing the extended crank

He had a similar problem with his '99. It turned out to be a check valve which maintains fuel pressure between the fuel pump and fuel rail when the ignition is off.

He mentioned it in post #30 & 32 of this fuel related thread: http://forums.corvetteforum.com/show....php?t=1758904
