hey guys, i can't seem to get my car (88 4dr LX) started.. it seems that my fuel pump is not pumping for some reason, even though i can hear it hum for a couple seconds when i turn the key to on. i have noticed that if I unground the fuel pump, then the seat belt warning beeper does not beep.. is it possible that i have a short in the wiring? or do they somehow share a ground.. it just seems kinda off the wall that the two would share a common ground.
