Silly question for sure, in that it makes me feel silly. (Sheepish)

The check engine light says "fuel injectors," so I replace a bunch of other stuff. Seriously makes me question my competence as a mechanic. Suppose I better keep the day job, eh?
Ok, just ran a search at the linked forum, turns up a guy with an almost identical problem ('90 Accord, same car) and a simple $55 fix ("main relay," whatever that is). The sole response was "You describe the textbook symptoms of a main relay failure."

Thanks a heap!!
