Hello and welcome to JustAnswer!

P0200 is for an injector control circuit issue. Even though the code is not setting presently it is still significant to the no start condition.

If cam and crank signals are present, data shows the injectors should be on and rail pressure meets setpoint while cranking then turn your attention to the injectors. You can try unplugging them one at a time to see if the engine will start. If that doesn't change anything then the control circuits should be checked for a short to power or ground and either load tested checked for continuity from the injectors to the ECM.

Yes, the control circuits will need to be tested for shorts and at least for continuity.
