Honda accord 93 ECU fuse keeps blowing

honda accord 93SE, ECU fuse keeps blowing, some one told me to check the relays. Which relays lay in this circuit, I seen another post that found he had the O2 sensor cable touching the manifol. Thanks for the help!!

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.
