Well, the TPS is on the driver side of the throttlebody. On the TPI cars (and I'm assuming LT1s too, since they use a similar throttlebody), the TPS is actually slotted, so that it can rotate clockwise/counterclockwise. If that's rotated too far one way or the other, the computer is gonna see way too much (or little) voltage and not allow the car to start.
I'd help if I wasnt' on the other side of North Jersey.
