1994 Ls 400 I Love it. Driving away from home , 2 miles out and the dash blinked and engine quit. I tried to start and no joy . It turns over normal. I checked Battery voltage , spark and fuses , all good. I don't here the fuel pump charging when I turn the key on. I changed the fuel pump relay. Again No joy. I had a tech guy come to read code after 2 hrs and several different attempts to get it to read . It said no code or unable to read ? I get the felling that it must be electrical , Any help would be gratefully appreciated.
