Thank you again for the response. I actually tested the triggerpoints by holding the distributor in hand and turning it clockwise. I verified that each set of the four sets of two paired injectors is firing. With respect to the wiring to each injector, that has been verified exhaustively. In fact, while the engine is running, I can take the injector plug from the non-running number five and connect it to cylinder number six and achieve combustion (obviously not optimal). However, that is not the case vice a versa. Keep in mind, these are new injectors with less then 40 miles on them. I plan on removing the driver side injector rail and swapping the injectors on contributing cylinders six and seven with those on the non-contributing cylinders five and eight (Probably evaluate spray pattern and 30 second volume test of 220 cc) By the way, the easiest way to verify that the injectors are indeed “firing” is to use the throttle switch after bumping the starter in order affect different iterations of the injector contact switches.
