The terminology may throw you. I’m pretty sure they originally called it a Powertrain Control Module for 95-under, calling it a Vehicle Control Module (VCM) starting with OBD-II in 96.

That's what I thought. Don't have a repair manual for my Tahoe yet and lost all fuel and spark. I think it's the PCM. Thanks!

You may have something easier/cheaper wrong, What codes do you have? Have you checked the Crank position sensor wiring for signal? Ignition control module for signal ? Look up a post of mine P1351 in title, there are good diagnostics that were graciously suggested by members here. I'll try to link it.
