Honestly didn't check lift pump at that moment.
But what I did check is that fuel rail pressure commanded vs measured were pretty much the same PSI.
If the lift pump failed at that moment would there be a pressure in the rail? And would there be any erro code referring to the lift pump? Any thoughts?
