A. not inject fuel if you have it floored prior to turning the key on, used to unflooding the car
B. may flood the engine if you floor it right after cranking the key over..
Don't give up though, I am determined as hell to figure this out so hopefully this will be some encouragement. Persistance pays off!

thats an interesting thought about the fuel pressure not holding. Though, i'm not sure on how i would check that out, I do have a new fuel pump and injectors, it does turn on, i get fuel into the lines and into the motor, but it doesn't seem like its getting "Constant" fuel... so in fact it might be a problem, how would i remedy this?

Well your pump and injectors may be new but something else electrical could have gone bad (relay, pump resistor, bad ground.. who knows). The best way to check this is to place a fuel pressure test gauge inline with the fuel feed line before it gets to the fuel rails, this way it is behind/before the pressure regulator. You can get these gauges for like $40 at any auto parts store.. just jump the fuel pump and verify that you are getting the right pressure. You should get ~40psi w/o the engine running.

Well i FINALLY got the car back on the street. you will never guess what it was.
MJW- i would suggest trying this, it might be your problem.
Well i changed the fuel filter and blew out the hardlines, still no fuel pressure.. pumps running and such.. the usual run around. We take the pump out.. well the O-Ring that goes from the pump to the Tube/hat had come out, and the pump was pumping the fuel, but when it would pump, some would dump back into the tank.. ie no fuel pressure. Reinstalled the o-ring and bent the bracket to make sure the fuel pump won't come lose again.. Btw i run a walbro fp...
I don't know if it will help you MJW. but my problems are solved. I'd like to thank everyone who helped me out! Remember... the 7 never dies.
