I have a 92 honda civic dx, whenever I turn key the ecu fuse blows so the car won't start. It still cranks but that's it, I had alternator checked and it was overcharging so I replaced it and still nothing, so I started messing with other fuses I found that if I take out the fuse that controls the alternator, pgm-fi, srs system, etc. that the ecu fuse does not blow when the key is turned, basically I am stumped now and cannot find a wiring diagram and hoping another honda lover could give me some insight

sounds like a short somewhere. ill have to find a wire diagram and see where it could be but id guess it has somthing to with PGMFI, have you done anything recently to the car?

Check the wiring and connection at the main relay and the main relay itself.
