Something else to keep in mind is the injectors. No idea if a ‘92 Dakota with a return style fuel system used a different sized injector than a ‘94 Dakota with a “returnless” system. I would look them up on RockAuto to check.
Not saying it is why the motor won’t start, just something to keep in mind.
Great information about how the different PCM's handle the different fuel systems. I agree that it's important to keep matching parts and systems together, or at least tune for the differences.
