Hotwired truck, Now won't start normal!!!!

[jorgensensc]

Heres the story:
I left my keys in Texas, Flew back to California. Got Roadside assistance to get me into the truck, made sure I watched where the wires connect on the back of the ignition (there is no harness). Hotwired the truck, no problem, put all the wires back where they came off of (exactly, yes I'm positive), accessories work, but when I try and start the truck, it will crank but won't start. I verified it was wired right by the wiring diagram and by tracing wires. The minute I put the key in run position, and take the purple (starter) wire and touch the red (battery) wire still hooked to the ignition, she fires right up!! Perfect!!! I never had a problem before I pulled the wires. One thing to note is that while I try and crank the truck (hooked up normally) it tries and tries and then the starter makes a crazy screeching noise. I pull the wire and touch it to the red (battery) wire and it starts right up and doesn't make the noise at all.
Is the ignition switch bad?
Is it coincidence or did I F$%# something up?
Any help would be greatly appreciated!! I'm getting tired of crawling under the dash and hotwiring my truck when I have the keys!!!
Thanks,
Shawn
