Second time it's happened.. I made a few short trips in a row, turning off my car at each. When I try to start the car, it starts but won't stay started. It does this several times in a row, then I turn it over and nothing.. I have power but no sound of the engine.. I need to know possibilities without running diagnostics. Cuz I'm sitting out here.. Unless you can give me directions using ignition.. Cuz I can't remember what you do to get the codes..
