My port engine is strong until about 3800 rpm, starboard is fine. Happened last 2 times out, had the Sunny 3 years now & never an issue with this engine. I put the rinda scanner on it & no abnormal fault codes, said 100% power avail from ecm. Did the induced misfire test on all 8 cylinders 3 times, all passed. IAC valve test good. No smoke or abnormal sounds. Leading me to believe its not getting enough fuel, changed the 3 screw drop in fuel filter, same results. Thinking now its the fuel pump. Any suggestions? The fuel pump looks like a real pain in the butt, any suggestions? or is it easier to remove the whole housing? Am planning on swapping to the other engine & water testing instead of throwing cash at parts I may not need. Thanks for any help.
