I don't know your vin? Some of my info shows a fuel prime connector behind the battery? A gray wire with electrical connector, nothing plugged into it. You can use jumper wire from battery positive to that connector, the fuel pump should run, no need to use the key. Do use an inline fuse on the jumper, see what happens? You could use jumper wires from your battery for voltage and ground to fuel pump connector, use inline fuse, gray wire is voltage, black wire is ground. That will bypass the system wiring harness. See if the pump runs ok, if it still blows the fuse, check wiring connector, if that is ok, what else could it be except the fuel pump? You did replace fuel filter?
