Try unplugging all your injectors and put all other connectors back in place and change the fuses again. Install all fuses and turn the ignition back to run with the injectors unplugged.
If the fuse does not blow again then turn the ignition off, plug them back in one at a time. Then turn the ignition back on each time.
If all this started when you ran out of fuel, then maybe one of the injectors ran dry and shorted to ground somehow.
Basically, what is happening is there is a short to ground somewhere that is blowing this fuse. When you are unplugging different parts of the system you are removing the power or ground to the short circuit and the fuse stops blowing.
So, if I am correct and an injector is causing this then when you disabled the ECM, you were removing the ground side of the circuit to the injectors.
Then when you remove the injector fuse, you are removing the power to the injectors. So, unplugging them should keep the fuse from blowing and then we just need to find which one. Keep in mind, it may be more than one so each time you plug one back in and the fuse blows, you will need to leave that one unplugged and test the rest just to be sure you get them all.
These types of repairs take a little while to sort out unless it is a simple circuit. This is a very complex circuit so we just need to narrow it down.
