YJ Starting issue
My '92 YJ will not start. Just before this issue, the 'Check Engine' light was on and off. Driving it home one night, stopped to get food, hasn't started since. Had it towed into work. Changed the battery, starter and alternator, even checked the battery cables, no dice. Tried to start it again, Ignition fuse (the 40amp in the main fuse block next to the battery) instantly blew out. swapped it out, blew out again. Any ideas?
