Hello and thank you for your question,

When it did not start where you hearing the fuel pump cycle on when you turned the key on and off?

Customer: replied 1 year ago.
Did not notice, was not listening for it.
Expert:  Ron replied 1 year ago.

It common for the fuel pump to fail due to worn brushes and its also common for the pump to come and go, before you consider replacing the pump I would take your 12 volt test light and or volt meter and check and see if you have key on engine cranking power in and out of the inertia switch while the no start condition is present. If you find you have power in and out of it while cranking then you very likely have a failing fuel pump. Check this if you can duplicate the problem and post back if need be and we can work from there.
