For the ECM 1 fuse to open you obviously have a short to ground , start with the injector disconnected and see if ECM 1 fuse still blows.If it does disconnect crank sensor, also inspect wires for the injectors or any rub through wires here is a diagram
Disconnect (unplug) all the units that are supplied by the 25A fuse.
Switch on ignition and check that fuse has not blown- if it blows under these conditions the short or overload to ground is:-
a) in the wiring to one of the units,
b) or there is some other unidentified faulty unit still connected.
Re-connect each unit one at a time, observing fuse status.
If one of the units has a short / fault, it will blow the fuse when it is connected back in circuit.
