What the hell did i do to her?

[Mad_skids]

let me start with a short summary of my first post....yesterday...when my 1991 z32 NA 2+2 was running great:

-- "Blah Blah Blah, never worked on cars before, but I'm going to do it myself...im worried about my jack points and jack stands....i just want to care for my own baby....Blah blah" --

so today, i rolled up my sleeves and said fine, i can do this. had the jack points in my head and the production manual out to make sure i had all my areas covered. My z is reasonably low so i rolled her up on to two wood planks like I've seen done before. had my tire stoppers in the back and went to work.

well yeah, i was on the wrong spot, http://imgur.com/syKOOZg

the jack was under what i thought was a strong part of the support beam, got it about a foot off the ground on the passenger side, and i heard it start making a noise you know, that slow bending metal noise... i immediately (slowly) lowered the car back down and noticed the four thin lines encased in a plastic bolted next to the beam( running to the back) were not straight anymore. they were before i jacked the car up.

and to my horror, the steering wheel was locked, so i push the car off the planks of wood the break pedal won't move an inch and there is literally ZERO sounds when i turn the ignition.
there are no fluids draining. other then the oil pan leak that i knew about already (could also be a rear main seal)
there is power in the keys first position....
what the hell did i do?

yeah so you used the plastic covers NOT the structure of the car. The structural frame portion is further toward the center of the car.

You probably crushed brake lines. When you use a floor jack to jack up the front use the cross member the part circled on your diagram. Don't try to jack up one side.

ok, so took me a two days to run through everything..it was dark both last night and tonight when i got home. iPhone light just not cutting it... with that said, everything looks fine and is in order. (hah, i say that like id notice something unless it was unplugged) but it seems the brake lines made it fine just the plastic cover warped. so now with the key in and the first position turning on the power and warning lights fine...and with zero sounds or anything from turning the key further. I noticed the " security" light is flashing when previously it was always solid when I turned the key before..im going with the security and immobilizer system being tripped/activated by my jacking and letting the car down? ummm. i guess I'm coming home for lunch break and unclipping that. called my nissan dealer here in RVA and they told me where to find it. its fairly simple to find near the CPU. everyone cross your fingers

Hey did you ever fix that problem?

[Mad_skids]

yes, it was the immobilizer. google it and you'll find it next to the ecu. just unplugged it and plugged it back in after a minute. fired right up.
