It's unlikely the accumulator is an issue

Watch the actual Control Pressure during start-up, from the earlier logs the initial few warm cranking events showed CP pegged at round 100PSI, I still suspect there is an overpressure or inrush issue when the fuel pumps startup that is holding the injector shut.

With such a high CP there will be no fuel delivered and as it's warm the Cold Start Injector is not providing any help for the initial kick to pull the air plate against the CP resistance

for peace of mind, I'd remove a variable by reintroducing the original Bosch WUR instead of the eWUR, and look at bringing the eWUR into play later in the tuning phase if required.
Especially as you know the Bosch WUR works and our tuning target is focused on the Frequency Valve anyway
