4. Hold the accelerator completely to the floorboard while cranking.

You don't mention the age of the glow plugs. If you are glowing multiple times and it barely starts, I think you either have weak glow from old GPs, or at least two not working at all. As long as the #1 plug is working, the glow light will show on the dash. That doesn't mean you have adequate heat.
My experience has been that here in cold eastern Canada, valve adjustment issues often show up before the temp you describe. As Graham pointed out, around here 28 F (-2 C) is hardly even a cold day at this time of year. The motor would have to have very low compression figures to refuse to start at that temp. (I know -- I drove a high-miler 300sd with a pooched motor through one winter.)
Tonight in my area we are going down to -31 C (-24 F) and the windchill factor will be -42 F.
