Sure enough, it started briefly while spraying carb cleaner into the TB. But it wouldn’t stay running. It was looking more and more like a fuel delivery issue, but I still suspect it is electronically failing. Live data was continuously showing “open loop due to insufficient engine temperature”.OK, so P0191 is a fuel rail pressure code.
Sputtered and died. This says you aren't getting gas!
Quick and easy check. Pull the air intake hose, give it a shot of brake cleaner or starter fluid. If it cranks right up and runs, see if you can keep it alive on the sauce.
Of course, do the regular checks, see if you hear the EFI pump priming for 3 seconds when you turn the key to ON, etc.

After sundown it started up and ran great for a test drive.
Strange as it seems, there is a correlation between ambient temp and the engine deciding to start. I live in San Diego where temp has little fluctuations, and it always runs fine when under 70F.
