Replaced injectors now have no spark?

Hello, you are correct about the 2 coil packs being waste spark system, the igniters are built into each coil, (ill post a diagram showing the inner workings of the coils). But if you had spark prior to the injector replacement, I would retrace your steps in the areas you were working in the truck, check any connectors for loose pins or poor fitment.
And where did the injectors come from? And are the injectors being fired as well?
I will pull up the wiring diagrams so you can check the wiring.

The first diagram is both coils, diagrams 2,3(Top & Bottom) are the aftermarket drawings, 4th diagram is the resistance spec for checking the coils, and diagram 5 is the oem wiring for the coils that shows the internal workings of the ECM ignition coil control.
If the new injectors installed were not oem from Toyota, I would be concerned about that as well, we are seeing a rash of bad brand new parts, but if they are not Toyota injectors it can cause any number of issues.

This is the procedure for checking the Secondary windings of each coil, let us know what you find.
