i had the same problem when i put my engine in, check the grounds for the wiring it caused it to no crank.

The flashing security light indicates that the VAT system is engaged. It expects a key with a certain resistance or it won't allow the car to start. Anyway, as the key and lock cylindeer 'age' sometimes there are problems. If you have a spare key, try that. If you need more help after that, Shoebox's page can help: http://shbox.com/1/pass_key.html

Good luck!

if the the key pellet were to lose contact while the car was running would this cause it to loose spark ?

No. There is no spark cut-off. Additionally, nothing will happen while the engine is running, except that the security lamp will come on.

Anyone that has ever transplanted an LT1 into another body type has had to do this. Just follow the recommendations on the page.

i havent had time to work on the car till today and when i got to it, it looks like some one had already tried messing with the vats system in this car so im kind of at a dead end unless i can get some under dash pics of an un tammpered vats module looks like.
