well i found the problem! i unplugged the fuel pump and i had spark so i plugged it back in and it started right up. and as soon as i revved it i saw sparks coming from the o2 sensor wire sitting right on the headers and it blew the fuse again and died.

Glad you found the problem before it was too late


If a circuit requires a specific amperage fuse, don't chance fate with a higher amperage one.
