Somehow I posted this in the internal section but deleted it. It probably makes more sense to ask here anyway.

On a 10' Camaro LS3, what sensors does the PCM use to fire the injectors?

I spent a couple hours reading through the service manuals I have available to me but couldn't find a definite answer.

Does it use the CKP and the CMP or just the CMP? I've read both but I'm unsure.

Thanks for an help.

It uses the crank sensor. You can unplug the cam sensor and the engine will still run, unplug the crank sensor and you'll have no spark and no injector pulse.
