its something ignition related. Your rpm says "syncing" the entire time. It should read that for a half a second before you see the rpms register in the tach.

it looked like it was trying there but I am not sure what to recommend. Do you have it set up for digital rising or falling in the settings? There is a facebook holley efi group that is pretty good at answering questions. Have you started to regret the choice to go stand alone yet? It comes and goes.
So close yet so far

Check your data log and see what your voltage is dropping too during cranking.
Did you do a TPS Autoset? It won't register RPM while cranking until you do that.
Are you going to dabble in tuning yourself?
