Installed GIAC chip => car won't start. Help!

I tried installing a GIAC chip tonight and my car doesn't start. I tried everything under the sun but nothing works... My GIAC chip came with one of those security board things... seems that not everyone is getting these, but I did. Anyways...
I did these steps to install the chip:
1) Disconnected negative battery cable
2) Took out ECU and removed the stock chip
3) Plugged in GIAC chip with the security board it comes with
4) Put the ECU back, reconnected battery
5) Turned key to ACC and waited 3 mins
6) Tried to start the car...
The car simply won't turn over and actually start.. it sits there and cranks, and cranks, but doesn't start.
My first thought was that I didn't plug the chip in properly.. so I went back in, and made sure it was. I also made sure the connector to teh ECU was also firmly seated. Still didn't start.
I thought I might have fried the ECU, so I just plugged the stock chip back in to test it. The car started perfectly.
Last thing I tried was removing the GIAC chip from the security board and putting it into the ECU directly. Still no luck!
What the heck is going on?
I was thinking it could be a chip coded from the wrong ECU # (mine is 259 AA), but from what I've read on the 'tex, that would result in my car running really rough and even stall -- however, my car should still start.
Currently my car starts fine with the stock chip, but I'd like to get this GIAC chip installed
Anyone have any ideas?

Hey Bobby,
Same thing happened with my TT chip. I got mine from Matt at Evolution in Everett. WE tried to install it at a local GTG and same symptoms.
Car tries to start but just cranks...
Put the stock back, everything is fine..
I called Matt the following Tues and they told him it just didnt burn all the way through. Sent him another one and I picked it up on a Thursday.
Superstar came over to help me with a chip puller on Friday. Worked perfectly fine.
Call where you got it, return it and get another one. The wait is the bhitch but at least it will be in there soon enough.
Good luck... http://****************.com/smile/emthup.gif

Ya, unfortunate about the wait.
Wooo was the wife steaming when it wouldnt start.....

But all good, Matt was great.
Waited a week plus another to get the replacement.
Absence makes the heart grow fonder...

It will be well worth the wait....... http://****************.com/smile/emthup.gif
