help. blowing ecm fuse
My 89 tbi camaro is blowing the ecm fuse at key on position. Followed orange wire to passenger side fender to a splliter ( two orange wires to oil pressure and fuel pump relay. And to that ecm fuse. Two wires from that 5 wire coupling go to the ecm under the passanger dash. Orange wire looks good. What else should I inspect that could cause the ecumenical to blow?

Check for a short on all the power pins on your ECU. Also check for a short with any components also on the same circuit with that fuse.

Decided to take off the wiring behind the dash and relocate it to the trunk. Fuse box
