Nobody has said VATS yet.
When you turn the key to the acc. position, during the lamp test, see if you see a light that says Security. Could be as dumb as a coincidence of burnt out bulb and the VATS module has gone south, or as simple as a chafed resistor wire on the lock cylinder. Have taken VATS apart, bypassed, but never had to troubleshoot a VATS problem in person. Worth mentioning.
Said when he turns it by hand he gets spark, but from turning the key, no go...

I was just woundering if before you pulled it all apart you checked for spark with a good checker? and did you check fuel pressure? Just wanted to know and did nt see it anywhere when i wass re reading all the posts

Truthfully the 12v you have at the coild comes throught the ign switch via the theft deterent. So if you have 12 V contant there when the key is turned on its good, unless the 12 v goes away as you turn the key to start. Since the car turns over you also know that the theft deterent is OK.
but the gay part of this is my car doesnt even really show any signs of a bad ignition switch.......iono

just took the steering column out and installed a new ignition switch..it still drops voltage in the start position...but at least i know its been changed if i ever have any future problems.
would anyone have a schematic on the ignition switch so i can see which wire supplies power when the key is in the start position.

Definitely want to see the outcome of this. Went through the same problem but I haven't got it rectified so I am just switching to a whole new ignition system altogether removing the opti altogether. But, I did too test out my ignition switch because of so many other people w/ similiar issues etc.

i studied this schematic earlier from shbox's site...http://shbox.com/1/ignswschematic96.jpg
according to this the pink wires should have 12v whether the key is in run or in start.i installed new ignition switch today and it still only has power in run but not start. would the lock cylinder have any part in this or do i need to stay focused on the switch and wiring?
now i know i can easily incorporate switched power with a relay but i want to keep this "factory" and less complicated...

Sounds like you need to start checking all of the wiring. Maybe something got burned or grounded out. I had a very similar problem as you once and trailed everywire under the hood and alot in the dash. I found lots of burnt and stripped wires.
Are you're injectors pulsing?
