Fitech- New install, no start.

Hi guys, got my tank up today, poured a few gallons in and crossed my fingers. No start. Brand spanking new to EFI so not sure where to begin. I did the initial engine setup, not running timing control, can hear it getting a prime shot so it’s getting fuel but it’s acting like it’s flooded cracking the throttle doesn’t seem to help. Neighbor gave it a shot of ether when cranking and it fired for a second, big buff like it was flooded and died immediately. Getting RPM signal on the handheld while cranking so im pretty confident with the wiring. Anyone have a similar setup with some baseline parameters to get it running?
