    Apply 12V to the pump and see if it runs, if it runs loosen the banjo
    bolt and see if pressurized fuel sprays out.

    when my mechanic was testing to see if i had fuel pressure (b4 he told
    me about gentaly tapping the pump) he dove under the hood and quickely
    determined there was no fuel pressure...some line or hose going into
    the injection system i would guess.....i think he wrenched loose one
    line or bolt...

    He loosened up the fuel delivery line at its fitting.
