Having problems with your 1989 Toyota Pickup SR5 ?

I own a 89 toyota toyopet truck. The EFI fuse keeps blowing every time I replace it and turn the key on. Tracked and tested all wiring related to this problem. All test good and look good. replaced all modules and sensors related to this problem. replaced altenator twice because voltage regulator is on inside, each time replaced truck would start and run for 20-30 seconds before the EFI fuse blows and truck dies. please help me fix my truck. my name is Tami.

I had the same problem with my 1990 P/u. It turned out to be the O2 sensor touching the underside of my box shorting and blowing the EFI Fuse
