You need to be sure about the injector pulse, I don't know how you checked for pulse? Because of the air plenum covering the injectors, they are hard to get at.
There may be a four wire injector connector on the backside of the air plenum, easier to get at. You can do some testing there. If your not sure of the connector, look at the wiring color. The solid pink wire is B+ for 1 bank, the ground for the same bank is light blue.
The B+ wire for the second bank is pink with black stripe, the ground for the same bank is light green.
If there is spark and no injector pulse, I would suspect the ignition module. If there is spark and injector pulse, then I don't suspect the module. You need to be sure about the injector pulse.
If you don't have a wiring diagram for your vehicle, the autozone site should have one. After you bring up the web page, click on (vehicle repair guides) and follow the links. I believe the wiring diagrams would be under (chassis electrical).
