Need Help Quick.....PLease

i don't know for sure, but i'd check to see the ignition switch is still good.

if it still cranks when the batt is reconected without touching the key id look toward the neutral safety switch(automatic) and see if the solonioid wire got shorted to the reverse light power wire. if i dosnt id say the autostart/security system went bad (thats what it sounds like) if none of that comes to anything follow any wire coming off the starter side of the solonoid and see if is shorting to the s terminal

I would try another starter solenoid because you might have gotten a bad one, it happened to me before. Also are you sure to got the wires right on it.
