There is a short somewhere in the wiring, first place I would look is the small wire going to the starter.

I agree with Rowefast. Short at the starter or in the ignition switch itself.

what would be the best way to check thanks

ok so i have unwrap the wires from the fuse box to the starter and found no shorts cuts or burns and i clean the ground that goes to the starter now it starts to turn over then the fuse blows could it be the starter itself?

Disconnect the wires from the starter, make sure they do not touch anything or each other, and turn the ignition key to see if you can get the fuse to blow.

yes it still blows

So it is not in the starter. Short somewhere, I'm thinking....

what do you think the next best thing to try

Unless there is a wire shorted somewhere, all I am coming up with is the ignition switch itself. Find it and unplug it and see if a fuse blows. Look for bad wires around the switch.

where the key goes in or the black box on the other side

Not were the key go's in, probably that black box. What does the plugin look like, I'll stay here.

This is what I am looking at, there is one other style, just scroll down on this page.

yes thats it sorry had to run get more fuses

74,715

Well that is what I am thinking, You didn't think to pick one up along the way?

ok so i unpluged it and turn the key and fuse did not blow does that mean its bad?

no i didnt

Not necessarily, I just hope it is not a wire in the steering column. At this point that is all I would know to try short of testing the wiring from the plugin you just unplugged. That takes time, up to you if you just want to try an ignition switch. Didn't look that expensive.

how would i test it

already have steering column housing and under dash takin apart all wires look good

74,715

Well to test that ignition switch you would need a wiring diagram on it, and use a digital volt, ohm meter. I wouldn't know where to find one. I was talking checking the wiring from the plugin on out. You have to follow the wires to see where they go, unplug where they go and such.

I'd go with the ignition switch.

ok will do and i will let you know thanks alot been at it since last friday but today was the 1st day i could really get at it

74,715

See if the parts store can test the ignition switch.

well its not the switch got a new one and still blowing the fuse so back to the wires

come up with anything else i will let you all know thanks for the help

Just got done watching the Packers Win! What a game! Ok then, so the fuse still blows, that blows....I would start at the fuse box at the circuit that the fuse blows on, test wires from each side of the fuse connection back.I'm thinking one of those sides run up to the ignition switch connector. I don't know where the other side goes. I have some sights with wiring diagrams that I will see if I can decipher. May want to pull back the fuse box to see behind it.
