SOURCE: 94 isuzu trooper turn key fuel pump runs for 2sec.and shuts off?
Can you hear a click during that 2 secounds? Thats the relay shutting off the pump just what its suppost to do. The pump does not run contenuosly, if it did it would burn up, thats what the relay is for, it kicks on and off to maintain the correct pressure to engine as needed. It will not turn back on until it resets itself because engine was not running, thats the way there designed.
SOURCE: When pushing the turn signal lever up to make a
check the flasher, you may have to replace it.
