blown engine fuse

ok soooo heres the deal still cant figure out what is blowing my engine fuse i disconected fuel pum and coil pack changed the computer changed asd and fuel pump relay .. checked under the carpet in the harness for frayed wires and still pops when the key is in the on position any ideas???

Check for shorts in the wires.

Check your wires for a stereo if its an aftermarket stereo

sounds like you need to go around and un plug sensor by sensor on your engine. Something isn't right here.. get yourself a TON of fuses, un plug all your sensors, with the key on one by one plug your sensors in. With every sensor you plug in check your fuse.. I'm not saying this will work but there's a possibility it may. Also un hook your ECU and make sure theres no shorts on the actual plug to your ECU.. After all of that youll want to check all your grounds on your engine, transmission, exhaust etc.. You can never look too close, you never know when the problem could be a simple chafe in a wire or a melted plug.... just keep your eyes peeled, and if you need any other 420a help dont be afraid to ask, I feel as If I may be one of the only people on here thats doing up a 420a and I know them in and out..lol

I agree i would first inspect all wires,make sure their aint any fraid wires or wires exposed. Than do what whiskeythrottle said.
