1993 Toyota Corolla ignition fuse blows 30amp no start

1993 toyota corolla dx wagon does not start.
Stalled while driving, has not started since.
Ignition fuse blows.30Amp in engine bay.
Checked for shorted wires, could not find.
Disconnected alternator and starter, still blows fuse.
disconnected distributor, still blows fuse.
Checked starting switch, 0.5 ohm
checked distributor
coil 1ary resistance 1ohm, secondary, 11kohm
pickup coil, says.200 and.400(G-G+ and NE-Ne+)
checked Te1E1 diagnostic, no check engine code at all.

Is it a bad relay. Tomorrow I go to junkyard to get relay, fuse box, distributor and more 30 amp fuses( blew 10 already testing).
Will appreciate any fresh ideas. Thanks.

ps. Had an aftermarket alarm; discoinnected all spliced in wires and reconnected ignition key cable that was cut to install alarm. Alarm is a chapman(probaly 10 or more years old).
ps2. Now the fan turns on(and of course coolant is cold, since it won't start)

Someone suggested I check the radio for a short there( thanks for the idea). I will check that.
It makes sense. I already had a similar electrical problem with another car. I was installing a stereo and when I turned on the ignition, it would start blinking on and off. Turned out to be that I forgot to untie some cables I had shorted in the turn signal light( I was repairing the left fender and the cables were tied together).

ps. Forgot to mention the starter is working. Turns engine. But no spark in plugs(tested with those flashing spark cable light tester).
could not check if fuel is sent because the fuse blows.
How can I test fuel pump ( maybe disconnect and send test lead to +.
How could I test if starter has a relay that is no working right( does it have a relay inside the startert unit?)
Any more ideas are welcome(im already at the point of bANGING MY HEAD TO A WALL)
