Al, you're having a problem for 3 weeks and just now tell us? :-(
Are yopu shure it is pin 19 on the ecu? because if you ground that, the a relay comes up that gives + 12v to the coils, a good thing, but also to the fuel pump and injection coils. And you tell us the pump runs?? If they connect their wire to the ground, you hear a relay click? The coils need 12v on one side, that can be checked easy. Also if that's not there.
IF it is pin 19 that doesn't contact to ground there is a reason for this, the ecu is missing a signal on an input, so it won't set the output free, or is defect.
