anyone know of a bypass in the fuel lines or know if a bad computer will keep fuel from reaching the motor? please help ive done all i can, i've changed the fuel pump twice, i changed the filter, i got a new main relay.. i'm just stumped i can hear the pump but no fuel comes up and i do have gas

The '90 Integra has a very conventional system, once the fuel pump is running. The pump output feeds the passenger end of the fuel rail through the filter, and the excess flow is bled off by the fuel pressure regulator at the driver's end and is returned to the tank.































You can loosen the banjo connection on the passenger end of the fuel rail after running the pump to see if fuel sprays out of the gaps. If not, either the pump is not running after all, or there is a blockage somewhere in the system. If so, then the injectors must not be opening.
