The few seconds is normal as the ECM controls the relay to build rail pressure in anticipation of cranking. Check the fuel pump fuse in the underhood fuse center. If it is blown, you could have a short, but it is more probable that the fuel pump has high resistance and is drawing too many amps and opened the fuse.
