Either the fuel pump or the fuel pump sending unit is shorted. Here is a diagnostic that can determine which one if you are able to do it. >> 1. At the circuit opening relay connect a 7.5 amp fused power supply to the Blue wire. Check to see if the fuse blows when the pump is operating.

2. At the fuel pump sending unit, connect a 7.5 amp fused power supply to the Blue wire. Check to see if the fuse blows when the pump is operating.

3. Check the fuel pump sending unit where the wires go through the top of the fuel tank for being shorted.
Potential Causes: Fuel Sending Unit — Fuel pump sending unit.
