Don't know if anyone is interested, but the cause of this was a short at
a wire connecting to the altinater.  The wire still looked connected
because it was held on by the factory molded boot.  It was actually just
sitting in the boot no making contact.  This powers the fuel pump and the
hal sensor.  This brings power to the fuel pump relay, so even if the
relay trips there is nothing to trip thanks to any one who responded
