injector pulse?

ok well i went and ran the hot lead on the injectors today and put my inline fuses in. everything is gettin power 12 volts at each injector. when i crank it over they still retain there power. but i lost my damn pulse. none at all. everything is plugged in. what would make it lose all pulse all of a sudden? any ideas would be great. Thanks Ryan

EDIT. well went and connected the old power wires back up and it fired right up. WTF the pink and black striped wire is a constant hot correct? im just lost now...

Re: injector pulse?

Yes, the pink/black is fused ignition power. The blue and green wires are switched grounds from the ECM.

My guess is that you disturbed soem of the other wiring and/or connectiosn when performing the work, and may have something connected now. The grounds on the engine would be my first suspect.
