    Try cycling key 3 time, then try starting, if starts first try. pluged filter and maybe bad fuel pump even if you can hear pump run.
    Test fuel pressure.

    it could be your fuel pump,next time listen for it
    also the ecm turns it on when you begin to start it
    should run for a few seconds.if the ecm does not turn it on,the oil pressure switch will after cranking for about 15 seconds/oil pressure builds up
