Do you jump the fuel pump relay with a jumper wire while doing the injector test?
Usually, the test is done with all 4 injectors removed and placed on a towel. Jumper the pump and then raise the sensor plate. Do your injectors spray for a few seconds then stop?
Let me know if the test drive goes well.
If the injectors a spraying correctly and the sensor plate moves smoothly up and down, have you checked for vacuum leaks?
Does it idle normally? Does it jerk when you try to accelerate gently?

If I were you, I'd get a coffee can, pull all four injectors again, jumper the fuel pump, put out my cigarette and pull the sensor plate all the way up and watch them spray for about 10-12 seconds. They should make a high pitched squealing sound and really flow a nice cone shaped pattern. If this is the case, I give up. If it isn't the case, I would tend to blame the fuel pump or some kind of blokage
Now I know why you go by the name Ironman!
You didn't mention a new fuel filter (the one in the engine compartment), and thats the first and cheapest place to start. That filter is designed to protect all of the components downstream from it from contamination. When you remove the old one drain the intake end of it into a glass jar to see what kind of crud you may be dealing with. After disconnecting the fuel lines from it, loosen the clamp and slide it out carefully without tipping in order to reain as much fuel in it until you can tip it into the jar.
