Hello Sarah, check your owners manual to locate the fuse/relay location (if there is one) and its rating. The problem must be isolated as the fuse is designed to protect components in the system so if there is a short or a electrical problem that is causing a fuse to blow..this problem must be located or you will just continue to blow fuses.

Suspect fuel pump may be causing too much draw, it's on same circuit I believe. Have draw tested, or at least check & clean all connections at fuel pump and try, if that fails, replacing fuel filter to reduce possible load on fuel pump may help also.

it will not blow when ECM is disconnected, cause there is no power to the injectors when you disconnect the ECM. When you turn ignition on check for fuel pressure at fuel rail. Release pressure at nipple on fuel rail. If no pressure exists puel pump is shot. If there is pressure your fuel filter might be plugged.
