I had similar issues with old pump and new pump...this seemed to have fixed it...mine wouldn't catch after cranking either, except when cold from sitting over night:

Adding air in here is a good, temporary way to add in the airflow, which will be decayed out after the first 30 seconds or so.
I'm going to try the Cranking VE Table spreadsheet right now...
