Looking at the wiring diagram for you vehicle, I see the fuel pump is circuit it protected by a 10 amp fuse. The fuel pump is then switched on and off via a relay that is controlled by the engine control module (ECM). Fuses are designed to protect a circuit by "blowing" when too much current is being drawn. My guess that the fuel pump itself is likely faulty and is drawing too much current. A short somewhere in the circuit could also be causing your fuse to blow. Regardless, the fuse will continue to blow until you address the root cause of the problem. I suggest having a professional mechanic inspect and diagnose your electrical issue to have this problem fixed.
