Starter issue Maybe?

[mkelly]

I put a new starter on the blazer from NAPA. Now when I shift from Rev to Drive or put it in neutral the starter engages. It is a auto, column shift. I can turn the key to on and shift to neutral and start the truck with out touching the key. Any Ideas? I have traced all the wires from the starter and no bare spots. Could it be something it the column? Any advise/ideas welcome. Also it did not do this with the old starter.
