Try soaking the seeds overnight and presprouting by placing them between several layers of paper towel kept damp inside a plastic bag. Leave the bag unsealed on the kitchen counter. Check them regularly for sprouting.
Some seeds will sprout in three or four days; others will take as long as several weeks
Plant sprouted seeds in peat pots. Fill peat pots with soil-less planting medium 3/4 inch from the pot's rim. Moisten with water. Place 2 or 3 vine seeds on the soil and cover with 1/2 inch of soil-less mix. Water again gently. Planted peat pots should be kept moist and in a warm location until the seedlings are large enough to transplant. Start vines indoors 4 to 6 weeks before the last anticipated frost.

Nick first, then soak overnight
Any seeds floating on top the next day aren't any good
Try Bottom heating after planting?
Plant in at least 6" of wet soil. Plant seeds 1/4" down.
Instead of starting seeds in dirt, wrap in a damp paper towel then put in ziplock bags. This is the way I am trying.
Will repost when seeds germinate
Day 4 looks like something is happening!
***I tried these at work and they never germinated because it was too cold. Started a fresh set of morning glories and moonflowers. make sure you give the shell a good nick, the seeds will swell slightly overnight. I wrapped them in a moist paper towel and rolled them up, all seeds sprouted, just transplanted them into small pots.
