Ok Guys, Big update - I woke up this morning and I ran the DTC codes and it pointed towards the map sensor. I then realized I left it disconnected when I cleaned the fuel rail and intake manifold to install the injectors. It turns on and idles fine now.
Big thanks to C5Diag and ~Josh. I couldn't have done this without you both, thanks for your input and suggestions they were very much needed.
Best Regards,
Bobby

Hook up your fuel pressure gauge and see what the fuel pressure is static with key on..,now start the car and see what the fuel pressure does...have you checked for injector pulse at the injector connector ??...I have no idea about this injector pulser you are using !!...disconnect an injector and with your 12 volt test light connected to battery positive see if that test light blinks when probing the striped wire on the injector while cranking the engine over !!....you can spray a healthy toot of Brake Kleen into any vacuum line and see if the car attempts to start or starts...if it does you have a fueling issue !!
