Hey yall,been a while. Just replaced the pump and regulator after boat sitting up for 6 weeks and now she won't idle or run worth a dang under 1400rpm. Already know about reversion so thats not the case since it shuts down after about 10 seconds. Was thinking IAC but thats newer but humidity may have gotten the best of things in the engine well. Any ideas? Used the diagnostic chart but it ain't working.
