Okay, here's the latest update:
Still no change.
I've cranked the engine/charged battery 20 times. Best was one time it sputtered for 4 seconds.
Could the delivery valve o-rings cause this problem w/o showing signs of fuel leakage? In my experience, when the DV seals are shot, the engine will be hard starting, but will still start.

You got me paranoid so I metered out the GPs and they seem okay. Can't reach one w/o removing intake; also I checked them at the relay. I think the GP relay is unique to this model; it certainly isn't the same as the non-turbo. YIKES, I hope not.
On this topic, could a bad temperature sensor or over-voltage relay or rpm sensor, etc. cause a no start. This turbo's IP is festooned with pods unlike my non-turbos.

Fuel is reaching the return.
My next step is to thoroughly clean the pump and surrounding area then remove the inspection cover. I won't get to it for a few days now as bad weather is scheduled for the next few days. I'm also considering replacing the delivery valve o-rings seals and springs as I did on my non-turbo. Made a big difference in performance.
I'll keep you posted on my progress.
THANKS AGAIN EVERYONE!
