engine just died without sputter. wont turn over

What is your question?

never a problem before. 122,000 k only on the engine. runs great otherwise.. only thing different lately.. is im broke, so the tank has been more empty than full. this day in perticular.. my other half added syphoned gas so he could make it to the store...grrr. the gauge registers a 1/8 tank still, so it didnt run out of gas. i cant seem to hear the fuel pump, but she was never very loud. could it be clogged? or did somehting burn out the pump... relay?... when i try to start it, it will crank, but not turn over.. though other than not starting, nothing else sounds wrong. .
