Crank no start on 98 honda civic lx

I own a 98 honda civic lx and it will crank but
won't start. I began having this problem
when I was trying to fix what was a failed
attempt by the previous owner  to put a kill
switch on the vehicle. They had the ignition
wires put together with speaker wire which
causeday it to heat up and smoke up. I had
fixed the problem but I made a rookie
mistake of not covering the wire with and
electrical nut or electrical tape so when it
touched metal it sparked and shut
everything down. I checked all the fuses
under hood and inside replaced ecm
distribution spark plugs spark plug wires
checked timing  ( although I  don't know if I
understood it correctly?) Also replaceed
both fuse boxes. What can it be? Someone
please help?
