Primed it like 4 times, same result, pretty much 0psi in about 20 minutes. Fires right up on cold start, cranks for a bit on warm start, maybe vapor lock in the rails from heatsoak and low pressure?
Took a quick video of warm start, did not feather gas. Fuel pressure dropped from 44 to 10psi, but looks fine, wideband still reads 16+ for a few minutes.
Pump is an airtex from 2013 (stranded away at school, had no choice and worked fine).
