need help/advice...i have to rebuild my whole tbi setup, suggestions? tb? injectors?

i have 15000 dollars worth or crap sitting in the garage about 10 feet under the room i am sitting in right now. i need everyone's help to turn it into 15000 dollars worth of pavement pounding american muscle.

as some of you know, everything on my car has been redone in one way or another. as a lot of you also know, i cant even get the car to run well enough to take it out of the garage.

here is my plan. take everything apart/off the car and put it all back on. there is obviously something terribly wrong with something and i cant find it. hopefuly after doing this, i will habve at LEAST a reliabl, driveable car, and at MOST a mid 13 second TBI Camaro like it SHOULD be.

when i say "take it all apart" i dont mean everything...just most of the stuff that can go wrong. its basically a tuneup, but with a little extra attention to detail.

- take out and reinstall distributor in case it is off
- new plugs
- new cap
- new rotor
- check all electrical connections
- possibly replace some sensors (suggestions??)

and, the big one...decide once and for all which throttle body to use. i have the stock, 454, and holley. for the GM pod, i have stock and 80 pound injectos. what about fuel pressure? vacuum AFPR? i have always liked the idea of the holley base with the gm pod.

anything else i should be looking for? i want to make sure that when everything is taken care of it will RUN this time.

honestly, i dont know if my knock sensor is for a 350 or not. what should i look for when getting a new one? do you guys like GM sensors, or just what is available at teh parts places? i knwo a guy that cant use anything but a GM o2 sensor in his trans am, thast why i ask.

i just want to know what i should check out that could prevent it rom running correctlty.

thansk for all suggestions.
