The Yeast Won't Start

I had big plans to make a Steam Beer tonight for a church event in February.  I know it seems like a long way off but I'm making a total of 4 styles and it'll be here sooner than you think.
I want to serve well conditioned beer that is at the peak of flavor.
I think this Steam Beer recipe tastes best after about 6 weeks.
Anyway, I bought some California Lager yeast over the weekend and made a starter last night to ferment the wort I thought I'd be making tonight.

I made the starter using the same procedures I always use.  I boiled 1/2 pound of dry malt.  Chilled it. Sanitized a Ghost River growler and an airlock.  I mixed it all up and... nothing.  No bubbles even tonight after 24 hours.  I usually get activity within the first hour but as of right now... nothing.

Since I have no confidence in the yeast I'm going to postpone the brew.

I'll have to get a new pack of California Lager and start again.  I don't want to waste a good grist with unhealthy yeast.

The beer will have to be made another day.
