UPDATE of the UPDATE
Update: I went through the hassle of pulling the tank and replacing the pump with a known good one that I have, its not as strong but it didn't need to be to test the theory that the one in car is in process of going out and sure enough it is, so I have a new one on the way from Jegs I have a feeling all will be fixed at that point, the old filter was not very old apparently but I replaced it anyway before I went into the tank, no change so I swapped them out and bam bad pump so now I have a new pump on the way with a higher pressure rating to match the new injectors , the cat was perfect as I figured it was, new exhaust rarely has any issues like clogs, the only other part I decided to go ahead and order is the canister I figure why have all this new and an old canister so its on the way too also I am adding a second battery, Everett#2390, had a great idea with adding a second so I added one in the trunk using heavy duty cabling I got from home depot and the battery came out of my Avalanche and is 2 months old I will get it a new one when or if I drive it in the near future. I should have results by the end of the weekend and again thanks for all the input

injectors
OK I picked up a noid light and not a single injector is firing BUT even with starting fluid it does not fire up it did backfire through the throttle body and spit fire at me once , I have spark throughout the entire ignition system. coils, plugs, etc. is it the ECM that fires the Injectors?

assuming its not any of the sensors you have replaced i am sorta stumped. ignition fuse, heck double check all your fuses, inside car and under hood fuse boxes. injector fuse should be under hood. if the computer does not think the engine is turning over it will not fire the injectors. if vats (maybe theft alarm not sure) is not happy it will not let the injectors fire.

Final Update
It's running it was the ECU I swapped it out with one from the upul it yard from a near identical Camaro and it started right up, the ECU I bought from ebay that was supposed to be set to my vin did not work at all, just wasted money.
Thanks for all the help and advice guys

You installed a PCM from a junkyard without programming in your Vin or disabling the anti-theft system and it started? That is not suppose to work.
Sorry I did not see this earlier. No starts are pretty easy to track down but you would have needed a OBD2 blue tooth adapter ($12) and a smart phone.
