If you had one or more injectors resistance going low you lost one or both banks of injectors delivering fuel. No fuel no start. Most common complaint would be a no start on a hot engine. In this case only the one cylinder would drop and the appropriate P200 code for the injector circuit and a P300 for misfire detected would set with the MIL on.

After a few paragraphs I usually close the book and go back to banging out dents.
