goin through a swap right now with some problems i might add one of the mods are bigger injectors that were installed between the swaps... how can i test to see if they are actually pumping fuel? thanks

 

You can check them with an ohm meter to be sure the coils are intact. Then check the signal with a noid light. As long you have fuel pressure, you have to assume they are opening. You could have them flow tested by a pro.

If we knew what year you had, we could suggest another way to test them. On OBDII cars, you can hold open or shut off individual injectors while the car is running with a scanner.
