I transported an iMac Pro 2011 face down on a blanket, flat in my pickup. I had just checked it out before I was giving to someone. It now does not turn on. Any suggestions what could have caused this? Vibration? Was facedown incorrect?

There were no iMac Pros in 2011 so you must have the regular iMac. Can you confirm this is the 2011 model?
Do you hear a startup chime and nothing else, or does the power buttom do nothing?
Assuming is it a 2011 as stated, before trying to turn it on I would open the RAM door and remove, then reseat the RAM modules. It's possible for vibration to loosen RAM models in their slots.
True iMac Pros doe not have user-accessible RAM models
Fully reseating takes a strong, slow push, so support the top of the case with one hand while pushing the module with other.

Dunno… I’d suggest you start out with the basics first… reset smc/pmu+ zap pram 3-4 times on startup, per this link : https://www.macworld.com/article/224955/how-to-reset-a-macs-nvram-pram-and-smc.html and see what that gets you…
