Hi Allan

What is the history of this, did it stop while driving or just fail to start with no other symptoms

Sounds like ECU is not happy with something needed to unable start.

does fuel pressure match desired?

Does cam / crank switch to synced while
cranking.

I'm thinking chain may have jumped,A cam / crank sync would be good if you can get a known good to compare.

Can you confirm cranking speed with pico?

Ignition switches where a known problem & cheap to replace (less than £20) and will give your crank non start problem.
