I am installing 1X6 cedar fascia over 2X subfascia. The front of the fascia will be painted. Is it necessary to backprime the cedar? Since the fascia will be nailed directly to a subfascia, will there still be cupping if it is not backprimed? Any advice would be greatly appreciated.

yes and yes..even nailed up to the sub, it will be able to gain moisture.

Back in July I drove by a 1920's era rehab that I worked on for almost 2 years (part time, Engineering school) and I paid particular attention to the cedar siding. Spent more than a few hours priming and back priming all of the cedar siding. Still looked great after appx 10 yrs. Only thing I didn't like was the new color. BTW, the corners were weaved and I have more than a little bit of pride in the finished product.
One other item of interest, last time I saw a 'true' 2X. Had to sister a lot of studs due to termites. Flat wore out a drill trying to get through some of the heart pine beams for an addition after the fact............. I'm rambling, memory lane............thanks for listening.

The short answer is in the short term your paint job will last many times longer with the back primed wood, in the long term the wood (cedar in this case) will more than likely last longer due to the back priming preventing the wood from picking up moisture.
Best of luck back priming (Use Benjamin Moore Fresh Start).

What about pre-primed finger jointed cedar for exterior trim/fascia? Is there a need to "re-prime" the backs of those boards or is the factory-primed backside good enough?
Cheers,

IMO you should be in good shape as far as the factory prime on the back goes--Primer looses its "tooth" after a while so if the factory prime is in any question I would re-prime the face to protect your time investment. The older primer on the back may be no good for paint but should serve you well for protecting the wood . Im doing a 50's ranch here in Mn. and I bet I am replacing 25% of the oridginal siding and not a lick of backprime and every one I.m replacing is cupped and split.
Primer is cheap and worth it's weight in gold in the long run. Mike
Thanks for the advice. I backprimed the cedar and installed it.
