I own a 93 4Runner 3.0 A/T, Went to start it up ,heard a clicking from the what I believe was the EFI relay ,I found the 15 amp EFI fuse blown, swapped it out turned the key on and the fuse blew again , cked the wiring for obvious damage ,loose connections etc, tried again and blew again , any suggestions on were to start would be very helpful , Thanks

 

Not sure if the 3.0 is the same but I had a couple 22RE's do the same thing because the wire to the O2 sensor was touching the exhaust pipe.

Melted the insulation and shorted.

 

Thanks for the reply, I'm hopeing to start pulling things apart this week , Thats were I will start first....
