Thanks all for your good wishes...
Got another nugget of info about the new Z from the servicing dealer yesterday. I spoke to the service manager. This also explains the relatively good overall condition of the car. It was indeded exclusively service by the dealer. The car was well known at dealership as was the customer. He was one of those "special" customers that would only deal with the manager. The car was regularly driven from Southern California to Maine where he had residences. This explains the high miles, in a good way. Apparently no expense was spared in the maintenance of the car. The heads and clutch were not done but the differential, shocks, injectors, coils, wires, brakes, alternator and A/C compressor and tires were all done since 2015.
Given the history and condition of car I think I'm going to go for the best possible "survivor" status and see high many miles I can get out of it before the bottom end of the engine let's go.
Now I just have get those pesky secondaries working. So far I've done the pink wire test and confirmed the activation works. The vacuum pump barely runs with the ignition on so i don't see a leak. Power key light comes on. Oil temp gauge reads about 120 to 180 under normal driving. Going to check the fuel pumps next.
