92 isuzu trooper. Fuse to the fuel pump keeps blowing. Why?

(1992 Isuzu Trooper)
in Wesley Chapel, FL on July 27, 2018
92 isuzu trroper had a bad fuel pump. Relaced it. Got it running for about 30 seconds and then it died. Checked the fuel pump fuse under steering wheel and it blew. It had a 10 amp in. With the key off, i replaced it and blew again. Disconnected the fuel pump, replaced fuse and immediatly blew with the key off. Tried a few more times, and same result. Thank you for your time...

Evidently that isn’t the “fuel pump fuse” .. No power to pump circuit with key off .. Possibly the ecm fuse - should have fuse identification in owners manual.
