Did you say you turned the key to the 1st position and THEN connected the battery? Is this a certain procedure I don't know about?

It seems to me that would be a little dangerous because if you have the key on, if there's any arcing when you connect the battery cable it can seriously harm your electronics. Not saying that's what happened, but I'm curious why you'd do it that way.

I once disconnected my Immobilizer and when I connected it, the car was completely dead. No crank.

I disconnected the ground (with key off) and tapped it against the battery terminal 3 times, then reconnected it. Turned the key on and everything worked! Was it coincidence? I don't know but I remember a guy once told me you can reset the onboard computers that way. I took it with a grain of salt, but when you're desperate you'll try anything and it worked for me.
