Hi Cary,
    The fuel pump should come on for about 2 seconds as some as power is
applied to the computer / key turned on. After that the fuel pump will run
on any time there are hall pulses. The ecu energizes a fuel pump relay (in
engine compartment)  in turn the relay provides 12 volts to the fuel pump.
