Tom i think you need to get into the real world of mechanics and not the college way. I spent most of my weekends when i was younger working with my old man who was a master tech for jaguars as well as other jobs so i learnt the proper way to do these things. Not the college boy way.
If your car wont start, you check for fuel to the rail. Got fuel? If so, check for a spark. Got a spark? If so, move on. Is the rail pressure correct? Check pressure, Correct? Start checking sensors (which i will say is substantially easier to do with a multimeter than a code reader).
If you went into the real world of mechanics tom, you would discover that code readers are rarely used by proper mechanics. Problem is, the ecu doesnt really have a clue whats going on. If you had a car running on 3 cylinders because of a stuck injector, what could the code reader tell you? Maybe rail over pressure or if the wiring to the injector is damaged, a open circuit fault on that injector. Neither of them really tell you the fault.

Dont mean to sound harsh on you tom but youve never really worked in a garage. Not properly anyway. You might not be aware of this due to the fact that you haven't met him but Ruan is a highly knowledgeable person when it comes to cars. Tbh if i was stuck and needed help i would take his judgement over most on this forum and certainly you because yes youve done very well in college with your distinction, but its like i say with all courses. Its all well and good having the knowledge but you dont realise how applicable or not it is to the rear world till youve done it, which you havent.
