Most likely a short in the directional circuit. Start at the blubs and disconnect the connectors at the bulb sockets. disconnect one at a time and see if the fuse continues to blow. When the fuse stops blowing you have found which circuit it is. Also, this could be the stalk switch on the steering column. disconnect and see if the fuse blows, and don't forget the 4 way flasher switch also. Lastly, pull the relay and check if the fuse still blows.
I am assuming you are talking about the circuit that powers the key switch. I'm showing a fuseable link to the starter relay instead of a fuse. If it is the circuit that powers the switch, I would disconnect the switch and see if the fuse blows as each circuit is powered one at a time using a jumper wire. You can get 30amp circuit breakers that plug into the fuse slot to use while you are testing circuits. You may need a repair book or shop manual to find out what is powered by that fuse since it is most everything on the car.
I'm no expert but when you turn key to run position, this turns the fuel pump on if the pump is faulty i would think it would blow the fuse also. Or its your theory a short in the ignition system wiring.
something connected too ignition sdwitch has short to ground. remove all fuses except 20amp that blows turn on ignition see if blows. if not replace one by one till it does to isolate circuit. which fuse is blowing and where is it located.
It sounds like a bad ignition switch or something is grounding out.Try to isolate the problem to key positions.See if the fuse blows when you turn the key to ACC(when your dash lights come on without starting)If the fuse does not blow then when you go to start it and it blows it could be one of many problems,the more common ones could be ignition switch,wiring,starter relay,starter soleniod,or perhaps the starter itself is shorting out,this can sometimes happen when a starter goes bad.
