I'm trying figure out why my Number 8 20amp ignition fuse keeps blowing. I'm at a loss. It randomly wouldn't start yesterday so I checked and the fuse was blown. I tried unplugging both 02 sensors, coil packs, and two other plugs, I think one was the CAS and the other was next to the front 02 sensor on the valve cover.
Anyone have any ideas why it would do this?

 

Edit.. misread the question. Check for any frayed wires, you might need a wiring diagram and get out the multimeter, check for continuity with the ignition wiring and a ground source.

 

Know where I could find a good wiring diagram? I'm not good with electrical issues but I'll try anything. The car is stranded on the side of the road and Id rather it not stay there.

Thank you! Hopefully I can decipher this and figure out the issue

 

Well I went underneath of the steering wheel and swapped every relay with another one...it started right up and didn't blow a fuse. So I am not sure what the issue was, hopefully it doesn't return

 

Do you have something wired into that circuit that is not factory? If so its propbly pulling enough current to pop the fuse.
