Trying to solve electrical issues over the internet can be iffy at best.

The schematic shows 3 fuses involved in the ECU circuit but what needs to be known for a start is which fuse is blown?

1. 10 amp
2. 15 amp
3. 10 amp

The fuel pump is also tied in with the main relay so it’s possible for a dead and shorted pump to blow a fuse.  
Aged and dragging pumps can also be behind main relay failures, ignition switch failures, etc.
