My vehicle is not getting pulse reading on all injectors therefor not starting. Cam's and crank sensor are good. Any ideas or opinions? All fuses are good. Anyway that I can get a wiring diagram of ecm, engine fuse box and fuel injectors?

There is an ECM relay I would check along with the fuses.

Here are some guides with the diagrams you needed (below) so we can get started testing to fix the problem:

There is voltage on injectors but not getting the pulse on all six injecs. Since I do not possess a diagnostic tool with live data I can not check ECM or why its not sending ground to signal wire. So to me it has to be the Ecm and nothinh else.
