I recently installed an airdog ll 100 gpm and it pushes too much fuel that the check engine light turns on do you guys think that a bad fuel pressure regulator can cause this to happen and if not what can I do to fix this issue
Is it on all the time? I know with mine it goes on when I turn the key to accessory but goes off once I start cranking. I've used my Edge to read the codes before cranking it and nothing comes up..
