Where is the fuse on the fuel pump?

Everytime I turn the ignition on, I blow the fuse. The fuse is located in the slot marked ECMI. How do I find out if it is the pump, the relay, or anything else? I am assuming there is a short somewhere. I thought maybe I pinched a wire and am arcing out somewhere.

Why does the fuel pump fuse keep blowing?

The fuse that is blowing is the one that operates the relay, not the pump circuit. – the relay always has power (key on) and the ECM switches the ground. Old school method I always use in these instances is replace the fuse with a higher amp re-setting fuse like on electric window motors or electric seats!
