For me, mine has an odd cold starting gremlin. (Lycoming IO-360) It will rarely

time I run the starter. Weird.

You sure the aux pump is working? Could be you're priming by cranking
the engine pump which gets you the start on the second crank.

Not to say it can't be the aux pump, but I get the same symptom in my
Skyhawk, which has no fuel pump at all. In fact, it's finicky enough
that about a 4-second delay between crankings is best to guarantee a
start on the second try.
